The main Trans-Canada Highway is uniformly designated as Highway&nbsp;1 across the four western provinces. The British Columbia section of Highway&nbsp;1 is {{cvt|1,045|km}} long, beginning in [[Victoria, British Columbia|Victoria]] at the intersection of [[Douglas Street (Victoria, British Columbia)|Douglas Street]] and Dallas Road (where the "Mile&nbsp;0" plaque stands), and ending on the Alberta border at [[Kicking Horse Pass]]. The highway starts by passing northward along the east coast of [[Vancouver Island]] for {{cvt|99|km}} to [[Nanaimo]] along a mostly-four-lane, heavily-signalized highway. After passing through downtown Nanaimo on a small [[arterial road]], it enters the [[Departure Bay|Departure Bay Terminal]] and crosses the [[Strait of Georgia]] to [[Horseshoe Bay, West Vancouver|Horseshoe Bay]] via [[BC Ferries]]. From there, it travels through [[Metro Vancouver Regional District|Metro Vancouver]] on a four-to-eight-lane freeway before leaving the city and continuing as a four-lane freeway eastward up the [[Fraser Valley]] to [[Hope, British Columbia|Hope]]. There, the Trans-Canada Highway exits the freeway and turns north for {{cvt|186|km}} through [[Fraser Canyon]] and [[Thompson Canyon]] toward [[Cache Creek (British Columbia)|Cache Creek]], mostly as a two-lane rural highway with only occasional traffic lights, while the freeway continues on [[British Columbia Highway 5|Highway 5]]. Approaching [[Kamloops]], Highway&nbsp;1 re-enters a short freeway alignment with Highways 5 (and concurrent [[British Columbia Highway 97|97]]), before passing through Kamloops itself as a four-lane signalized highway. From Kamloops, the highway continues east as a mostly-two-lane rural highway through the Interior of British Columbia, with occasional passing lanes. It widens to a signalized four-lane arterial road for short stretches in [[Salmon Arm, British Columbia|Salmon Arm]], [[Revelstoke, British Columbia|Revelstoke]], and [[Golden, British Columbia|Golden]], but has no signal lights on it for most of its length. The highway crosses two high passes along its route: [[Rogers Pass (British Columbia)|Rogers Pass]] in [[Glacier National Park (Canada)|Glacier National Park]], and [[Kicking Horse Pass]] in [[Yoho National Park]]. At Kicking Horse Pass, the highest point on the whole Trans-Canada Highway system is reached, at {{cvt|1627|m}}.

Speed limits on the Mainland segment of the Trans-Canada Highway in British Columbia range from {{convert|90-100|km/h|abbr=on|mi/h}}, although in towns it can be as low as {{convert|50|km/h|abbr=on|mi/h}}. A combination of difficult terrain and growing urbanization limits posted speeds on the Vancouver Island section to {{cvt|50|kph}} in urban areas, {{convert|80|km/h|abbr=on}} over the [[Malahat, British Columbia|Malahat]] and through suburban areas, and a maximum of {{convert|90|km/h|abbr=on}} in rural areas.

The Trans-Canada Highway through the three prairie provinces is {{cvt|1,667|km}} long. It starts at the border with British Columbia at Kicking Horse Pass, and runs all the way to the Ontario border at Whiteshell. The highway continues through Alberta, running east for {{cvt|206|km}} as [[Alberta Highway&nbsp;1]] to [[Lake Louise (Alberta)|Lake Louise]], [[Banff, Alberta|Banff]], [[Canmore, Alberta|Canmore]], and [[Calgary]]. This section of the highway passes through [[Banff National Park]] and has significant tourism. The section of Highway&nbsp;1 through Banff National Park was also one of the first highways in North America to have wildlife crossing structures and fencing installed on it{{Citation needed|date=March 2024}}. After leaving the mountains it enters Calgary, where it becomes known as [[16 Avenue N]], a busy six-lane street with many signalized intersections.<ref name="ABmap">{{Google maps|url=https://www.google.ca/maps/@50.7253081,-112.997724,6.75z|title=Highway&nbsp;1 in Alberta|access-date=November 4, 2016}}</ref> For the next {{cvt|293|km}} after Calgary, the Trans-Canada Highway continues as a four-lane expressway, with few stops along its route. [[Medicine Hat]] is served by a series of six interchanges, after which the Trans-Canada crosses into Saskatchewan on the way to [[Moose Jaw]].<ref name="ABmap" /> The highway mainly travels straight as a four-lane route for most of these sections. The expressway continues {{cvt|79|km}} east to the city of [[Regina, Saskatchewan|Regina]], and skirts around the city on the [[Regina Bypass]], the most expensive infrastructure project in Saskatchewan to date{{As of?|date=May 2024}}. Beyond Regina, it continues east for {{cvt|486|km}}, across the border with Manitoba, to the cities of [[Brandon, Manitoba|Brandon]] and [[Portage la Prairie]], and finally {{cvt|84|km}} east to [[Winnipeg]].<ref name=SKMBmap/> The southern portion of Winnipeg's [[Perimeter Highway (Winnipeg)|Perimeter Highway]] (Highway&nbsp;100) is part of the Trans-Canada Highway system, and bypasses the city with a mix of traffic lights and interchanges, while Highway&nbsp;1 continues through central Winnipeg as a signalized arterial road.<ref name=SKMBmap>{{Google maps|url=https://www.google.ca/maps/@50.4422044,-104.2687269,5.5z|title=Trans-Canada Highway in Saskatchewan and Manitoba|access-date=November 4, 2016}}</ref>

With the exception of a {{convert|15.3|km|mi|adj=mid|-long}} stretch of two-lane highway just west of the Ontario border, the entire length of Highway&nbsp;1 through the Prairie Provinces is a four-lane highway. While the only true freeway sections of the route are along the Regina Bypass, in Medicine Hat, and between Calgary and Banff, the whole highway is largely stoplight-free, with "split" at-grade intersections forming the vast majority of the junctions.

The speed limit is restricted to {{cvt|90|kph}} through national parks in Canada, including Banff National Park. East of Banff, traffic on most of Highway&nbsp;1 through Alberta, Saskatchewan, and Manitoba<ref name="mbtchspeed">{{cite news |title = Manitoba Trans-Canada Speed Limit Goes Up to 110 km/h Today |publisher = CBC Manitoba |year = 2015 |url = http://www.cbc.ca/news/canada/manitoba/manitoba-trans-canada-speed-limit-goes-up-to-110-km-h-today-1.3096606 |access-date = June 2, 2015 |archive-date = July 4, 2015 |archive-url = https://web.archive.org/web/20150704133543/http://www.cbc.ca/news/canada/manitoba/manitoba-trans-canada-speed-limit-goes-up-to-110-km-h-today-1.3096606 |url-status = live }}</ref> is limited to {{convert|110|km/h|abbr=on}}, but is {{convert|100|km/h|abbr=on}} east of Winnipeg.

East of Winnipeg, the highway continues for over {{cvt|200|km}} to [[Kenora]], Ontario. At the provincial border, the expressway becomes an arterial highway, and the numeric designation of the highway changes from 1 to 17. It is signed with a provincial shield along with a numberless Trans-Canada Highway sign, and continues as an arterial highway along the main route across Northern and Eastern Ontario, until widening out to a freeway at Arnprior, near Ottawa.<ref name=ONmap>{{Google maps|url=https://www.google.ca/maps/@50.0370965,-87.9000881,4.25z|title=Trans-Canada Highway in Ontario|access-date=November 4, 2016}}</ref> In Kenora, the Trans-Canada designation includes both the main route through the city's urban core and the {{cvt|33.6|km}} [[Ontario Highway 17A|Highway&nbsp;17A]] bypass route to the north. The existing branch from Kenora continues east for {{cvt|136|km}} to [[Dryden, Ontario|Dryden]].<ref name=ONmap/> This section of highway passes through the [[Canadian Shield]], a rugged, forested area with thousands of lakes. There are many cottage communities along this section of the Trans-Canada Highway, some of which have their driveways directly onto the highway.

Highway&nbsp;11/Highway&nbsp;17 proceeds southeast for {{cvt|65|km}} to [[Thunder Bay]], then northeast for {{cvt|115|km}} to [[Nipigon]].<ref name=ONmap/> An {{convert|83|km|adj=on}} segment of the Trans-Canada Highway between Thunder Bay and Nipigon is commemorated as the ''[[Terry Fox]] Courage Highway''.<ref name=ONmap/> Fox was forced to abandon his cross-country [[Marathon of Hope]] run here, and a bronze statue of him was later erected in his honour. The highway is the only road that connects eastern and western Canada. On January 10, 2016, the [[Nipigon River Bridge]] suffered a mechanical failure, closing the Trans-Canada Highway for 17 hours; the only alternative was to go through the United States, around the south side of [[Lake Superior]].<ref>{{Cite news |url = http://www.cbc.ca/news/canada/thunder-bay/nipigon-bridge-transcanada-update-1.3398207 |title = Nipigon River Bridge on Trans-Canada Highway partially reopens |newspaper = CBC News |access-date = November 28, 2016 |archive-date = November 28, 2016 |archive-url = https://web.archive.org/web/20161128050741/http://www.cbc.ca/news/canada/thunder-bay/nipigon-bridge-transcanada-update-1.3398207 |url-status = live }}</ref>

Highway&nbsp;17 proceeds east from Nipigon for {{cvt|581|km}} along the northern and eastern coast of Lake Superior. Between [[Wawa, Ontario|Wawa]] and [[Sault Ste. Marie, Ontario|Sault Ste. Marie]], the highway crosses the [[Montreal River Hill]], which sometimes becomes a bottleneck on the system in the winter when inclement weather can make the steep grade virtually impassable.<ref name=nob>{{cite news |url = https://www.northernontariobusiness.com/industry-news/construction/the-montreal-river-hill-nine-years-for-nothing-364162 |title = The Montreal River hill: Nine years for nothing? |work = [[Northern Ontario Business]] |date = May 16, 2006 |access-date = November 17, 2016 |archive-date = November 16, 2016 |archive-url = https://web.archive.org/web/20161116231212/https://www.northernontariobusiness.com/industry-news/construction/the-montreal-river-hill-nine-years-for-nothing-364162 |url-status = live }}</ref> At Sault Ste. Marie, the main route turns eastward for {{cvt|291|km}} to [[Greater Sudbury|Sudbury]].

The mainline route then continues east from Sudbury for {{cvt|151|km}} to North Bay. The northern route rejoins the mainline here, which continues {{cvt|339|km}} to [[Arnprior]], where it widens to a freeway and becomes [[Ontario Highway 417|Highway&nbsp;417]]. The freeway continues to [[Ottawa]] passing through the city on Highway&nbsp;417, which is between six and eight lanes wide at this point. In [[Southern Ontario]], the speed limit is generally {{cvt|80|kph}} on the Trans-Canada, while in Northern Ontario it is {{cvt|90|kph}}. Sections routed along Highway&nbsp;417 outside urban Ottawa feature a higher limit of {{cvt|110|kph}}.<ref name="Eastmap">{{Google maps|url=https://www.google.ca/maps/@47.5427268,-67.9814063,4.75z|title=Trans-Canada Highway in Eastern Canada|access-date=November 4, 2016}}</ref>

While Highways&nbsp;17 and 417 are largely free from traffic congestion except for minor rush hour delays on Ottawa's stretch of Highway&nbsp;417, the non-freeway sections are subject to frequent closures due to crashes, especially in winter. It is considered a dangerous route due to its extensive outdated sections of winding two-lane highway.<ref name="nob" /> Because this section of the highway passes through a largely undeveloped and forested area, collisions with animals are a common cause of crashes. {{As of|2022|alt=As recently as 2022}}, Sault Ste.

Ontario plans{{As of?|date=May 2024}} to eventually extend the 417 freeway to Sudbury, which will widen the section of the mainline TCH between Ottawa and Sudbury to four-lane freeway standards. However, there is{{When|date=May 2024}} no funding secured for such a project, as Ontario is currently{{When|date=May 2024}} focusing on extending [[Ontario Highway 400|Highway&nbsp;400]] to Sudbury along the Highway&nbsp;69 corridor (which is part of the [[Georgian Bay]] TCH route).

It is notable that the Trans-Canada largely bypasses Canada's most heavily populated region, the [[Golden Horseshoe]] area of Southern Ontario, which includes Canada's largest city, [[Toronto]]. However, a short section of the Central Ontario branch does pass through the rural northeastern edge of [[Durham Region]] at both [[Sunderland, Ontario|Sunderland]] and [[Beaverton, Ontario|Beaverton]], which is officially part of the Greater Toronto Area. Access to Toronto itself from the mainline from Northern Ontario is via the non-TCH southern section of Highway 400, while access from Toronto to Quebec and points east is via [[Ontario Highway 401|Highway 401]] (North America's busiest highway and a major national highway in itself),<ref>{{cite web

[[File:Highway 20-Quebec.JPG|thumb|[[Quebec Autoroute 20]] eastbound]]
From Ottawa, the Trans-Canada Highway continues as a freeway and proceeds {{cvt|206|km}} east to [[Montreal]], as Highway&nbsp;417 in Ontario (and the Queensway in Ottawa) and {{lang|fr-CA|[[Quebec Autoroute 40|Autoroute&nbsp;40]]}} in Quebec.<ref name=Eastmap/> The Trans-Canada assumes the name {{lang|fr-CA|Autoroute Métropolitaine}} (also known as "The Met" or "Metropolitan Boulevard") as it traverses Montreal as an elevated freeway. At the Laurentian interchange, in Montreal, the Abitibi route (Highway&nbsp;66, Route&nbsp;117, A-15) rejoins the main TCH line. The TCH then follows [[Quebec Autoroute 25|Autoroute&nbsp;25]] southbound, crossing the [[Saint Lawrence River|St. Lawrence River]] through the 6-lane [[Louis-Hippolyte Lafontaine Bridge–Tunnel]], and proceeds northeast on [[Quebec Autoroute 20|Autoroute&nbsp;20]] for {{cvt|257|km}} to {{lang|fr-CA|[[Lévis, Quebec|Lévis]]|italic=no}} (across from [[Quebec City]]).

East of {{lang|fr-CA|Lévis|italic=no}}, the Trans-Canada Highway continues on Autoroute&nbsp;20 following the south bank of the St. Lawrence River to a junction just south of {{lang|fr-CA|[[Rivière-du-Loup]]|italic=no}}, {{cvt|173|km}} northeast of {{lang|fr-CA|Lévis|italic=no}}. At that junction, the highway turns southeast and changes designation to [[Quebec Autoroute 85|Autoroute&nbsp;85]] for {{cvt|43|km|}}, and then downgrades from a freeway to [[Quebec Route 185|Route&nbsp;185]], a non-Autoroute (not limited-access) standard highway for {{cvt|9|km|}} until [[Saint-Louis-du-Ha! Ha!]], where Autoroute 85 resumes once again. The portion from Autoroute&nbsp;20 to [[Edmundston]], New Brunswick, is approximately {{cvt|120|km}} long.<ref name=Eastmap/>

Since the Trans-Canada Highway for the most part follows Quebec's Autoroute System, which is always composed of a minimum four-lane freeway, travel through Quebec is generally, safe, fast, and congestion-free.{{citation needed|date=June 2023}} The exception is the route through Montreal, which can be prone to traffic congestion. However, drivers can bypass the city on the [[Toll highway|tolled]] Autoroute 30, which is not part of the Trans-Canada.

The maximum speed limit on the Quebec Autoroute System (including the TCH) is a strictly-enforced {{cvt|100|kph}}. However, the speed limit may be lower in select spots, such as through tunnels or major interchanges.

Since 2018, Quebec has been working on upgrading the {{Convert|40|km|mi|-long|abbr=out|adj=mid}} two-lane section of Trans-Canada Highway along [[Quebec Route 185|Route&nbsp;185]] to an Autoroute, with {{Convert|21.5|km|abbr=on}} of new freeway commissioned during 2021–22, another 10 km in 2024 and the remaining {{Convert|8.5|km|abbr=on}} of freeway under construction, with final completion targeted for 2026.<ref>{{Cite web |title=Réaménagement de la route 185 en autoroute (85) |trans-title=Redevelopment of Route 185 by Autoroute 85 |url=https://www.quebec.ca/transports/projets-routiers/bas-saint-laurent/reamenagement-route-185-autoroute-85 |access-date=April 30, 2024 |publisher=Gouvernement du Québec |language=fr |archive-date=April 30, 2024 |archive-url=https://web.archive.org/web/20240430135305/https://www.quebec.ca/transports/projets-routiers/bas-saint-laurent/reamenagement-route-185-autoroute-85 |url-status=live }}</ref>{{Update after|2024|12|reason=Update length as the remaining segments complete over the next few years}} Once this project is complete, the disconnected sections of Autoroute 85 will be joined, and all of Quebec's Mainline Trans-Canada Highway route will be minimum four-lane freeway standards. This will also result in the TCH becoming a continuous freeway from Arnprior, Ontario, to [[Lower South River, Nova Scotia]].

=== New Brunswick ===
{{Main|New Brunswick Route 2}}
The Trans-Canada Highway crosses into New Brunswick and becomes [[New Brunswick Route 2|Route&nbsp;2]] just northwest of [[Edmundston, New Brunswick|Edmundston]]. From Edmundston, the highway (again signed exclusively with the TCH shield) follows the [[Saint John River (New Brunswick)|Saint John River]] Valley, running south for {{cvt|170|km}} to [[Woodstock, New Brunswick|Woodstock]] (parallelling the [[Canada–United States border|Canada–US border]]) and then east for another {{cvt|102|km}} to pass through [[Fredericton]]. {{cvt|40|km}} east of Fredericton, the Saint John River turns south, whereby the highway crosses the river at [[Jemseg, New Brunswick|Jemseg]] and continues heading east to [[Moncton]] another {{cvt|135|km}} later. On November 1, 2007, New Brunswick completed a 20-year effort to convert its entire {{cvt|516|km}} section of the Trans-Canada Highway into a four-lane limited-access divided highway. The highway has a speed limit of {{convert|110|km/h|abbr=on}}<ref name=Eastmap/> on most of its sections in New Brunswick.

New Brunswick was the first province where the main route of the Trans-Canada Highway was made entirely into a four-lane limited-access divided highway.

From Moncton, the highway continues southeast for {{cvt|54|km}} to a junction at [[Aulac, New Brunswick|Aulac]] close to the New Brunswick–[[Nova Scotia]] border (near [[Sackville, New Brunswick|Sackville]]). Here, Trans-Canada Highway again splits into two routes, with the main route continuing to the nearby border with Nova Scotia as Route&nbsp;2, and a {{Convert|70|km|mi|adj=on}} route designated as [[New Brunswick Route 16|Route&nbsp;16]], which runs east to the [[Confederation Bridge]] at [[Cape Jourimain, New Brunswick|Cape Jourimain]].<ref name=Eastmap/>

=== Nova Scotia ===
[[File:NSHighway104 OutsideNewGlasgowWest.jpg|thumb|[[Nova Scotia Highway 104|Highway&nbsp;104]] in [[Nova Scotia]] near Westville]]
From the New Brunswick border, the main Trans-Canada Highway route continues east into [[Nova Scotia]] at [[Amherst, Nova Scotia|Amherst]], where it settles onto [[Nova Scotia Highway&nbsp;104]]. Southeast of Amherst, near [[Thomson Station, Nova Scotia|Thomson Station]], the highway traverses the [[Cobequid Pass]], a {{Convert|45|km|mi|adj=on}} [[toll road|tolled]] section ending at [[Masstown, Nova Scotia|Masstown]], before passing by [[Truro, Nova Scotia|Truro]], where it links with [[Nova Scotia Highway 102|Highway&nbsp;102]] to Halifax, {{cvt|117|km}} east of the New Brunswick border. [[Halifax Regional Municipality|Halifax]], like Toronto, is a provincial capital that the Trans-Canada Highway does not pass through. Beyond Truro, the highway continues east for {{cvt|57|km}} to New Glasgow, where it meets [[Nova Scotia Highway 106|Highway&nbsp;106]], before continuing to the [[Canso Causeway]], which crosses the [[Strait of Canso]] onto [[Cape Breton Island]] near [[Port Hawkesbury, Nova Scotia|Port Hawkesbury]]. From the Canso Causeway, the highway continues east, now designated as [[Nova Scotia Highway 105|Highway&nbsp;105]] on Cape Breton Island, until reaching the [[Marine Atlantic]] ferry terminal at [[North Sydney, Nova Scotia|North Sydney]].<ref name=Eastmap/>

=== Newfoundland and Labrador ===
[[File:Route1 nl.png|thumb|[[Newfoundland and Labrador Route 1|Route 1]] in [[Newfoundland and Labrador]] near [[Corner Brook]]]]
From North Sydney, a {{Convert|177|km|mi|adj=on}} ferry route, operated by the [[Crown corporation]] [[Marine Atlantic]], continues the highway to [[Newfoundland and Labrador|Newfoundland]], arriving at [[Channel-Port aux Basques]], whereby the Trans-Canada Highway assumes the designation of [[Newfoundland and Labrador Route 1|Highway&nbsp;1]] and runs northeast for {{cvt|219|km}} through [[Corner Brook]], east for another {{cvt|352|km}} through [[Gander, Newfoundland and Labrador|Gander]], and finally ends at [[St. John's, Newfoundland and Labrador|St. John's]], another {{cvt|334|km}} southeast, for a total of {{cvt|905|km}}, crossing the island.<ref name=Eastmap/> The majority of the Trans-Canada Highway in Newfoundland is undivided, though sections in Corner Brook, [[Grand Falls-Windsor, Newfoundland and Labrador|Grand Falls-Windsor]], [[Glovertown, Newfoundland and Labrador|Glovertown]], and a {{Convert|75|km|mi|adj=on}} section from [[Whitbourne, Newfoundland and Labrador|Whitbourne]] to St. John's are divided.<ref name=Eastmap/>

Although there does not appear to be any nationally-sanctioned "starting point" for the entire Trans-Canada Highway system, [[St. John's, Newfoundland and Labrador|St. John's]] has adopted this designation for the section of highway running in the city. The foot of East White Hills Road in St. John's, near [[Newfoundland and Labrador Route 30|Logy Bay Road]], would be a more precise starting point of the highway, where the road meets and transfers into the start of the Trans-Canada Highway. The terminus of the Trans-Canada Highway in [[Victoria, British Columbia|Victoria]], at the foot of [[Douglas Street (Victoria, British Columbia)|Douglas Street]] and Dallas Road at [[Beacon Hill Park]], is also marked by a "mile zero" monument. St. John's downtown arena, [[Mary Brown's Centre]], was originally branded under [[naming rights]] as "Mile One Centre" in reference to the geography of the region.<ref>{{cite news |last = Muret |first = Don |date = April 9, 2001 |title = Venue's Name Game Takes New Twist |work = Amusement Business |url = http://www.allbusiness.com/services/amusement-recreation-services/4568492-1.html |access-date = July 30, 2011 }}</ref><ref>{{Cite web |date = October 14, 2021 |title = The Biggest Mary: Chicken chain Mary Brown's buys naming rights to Mile One Centre |url = https://www.cbc.ca/news/canada/newfoundland-labrador/mary-browns-mile-one-name-change-1.6210704 |access-date = January 9, 2022 |website = CBC News |archive-date = October 30, 2021 |archive-url = https://web.archive.org/web/20211030133025/https://www.cbc.ca/news/canada/newfoundland-labrador/mary-browns-mile-one-name-change-1.6210704 |url-status = live }}</ref>

The usage of miles instead of kilometres at both designations dates back to when the Trans-Canada Highway was completed in 1962, prior to [[metrication in Canada]].
