No national plan for widening the Trans-Canada Highway exists,{{As of?|date=May 2024}} and all planning is currently{{As of?|date=May 2024}} done by the individual provinces, as the Trans-Canada Highway and highways within [[National Highway System (Canada)|National Highway System]] fall within provincial/territorial jurisdiction, with provincial/territorial governments responsible for planning, design, construction, operation, maintenance, and financing.<ref>{{Cite web |author = Transport Canada |title = Highways |url = https://tc.canada.ca/en/corporate-services/policies/highways |access-date = November 12, 2023 |publisher = Transport Canada |language = en-CA |archive-date = November 12, 2023 |archive-url = https://web.archive.org/web/20231112154405/https://tc.canada.ca/en/corporate-services/policies/highways |url-status = live }}</ref>  However, the federal government may contribute funding to highway projects through its various funding programs. Currently, there are five large-scale highway projects on the Trans-Canada Highway Network.

Quebec is{{When|date=May 2024}} working on completing Autoroute 85, bringing the last two-lane section of the mainline highway in Quebec up to four-lane freeway standards. {{As of|2021|09}}, only {{cvt|7|km}} of two-lane highway had not yet been addressed. The rest either had been completed or was currently under construction.

In Ontario, the province has several significant highway expansion projects on the Trans-Canada Highway planned or under way:{{When|date=May 2024}}

* Between Parry Sound and Sudbury, construction to upgrade Highway 69 from a two-lane highway to a 400-series freeway has been underway for decades, with the most recently completed section of freeway officially opened in December 2021,<ref>{{Cite press release |first1 = Dakota |last1 = Brasier |first2 = Simisola |last2 = Ikotun |title = Ontario Opens Newly Expanded Highway 69 |work = Ontario Newsroom |date = December 23, 2021 |url = https://news.ontario.ca/en/release/1001376/ontario-opens-newly-expanded-highway-69 |access-date = November 12, 2023 |archive-date = November 27, 2022 |archive-url = https://web.archive.org/web/20221127193210/https://news.ontario.ca/en/release/1001376/ontario-opens-newly-expanded-highway-69 |url-status = live }}</ref> leaving {{cvt|68|km|mi}} to be completed. 
* Between Arnprior and Renfrew, the province announced in 2019 the upgrading of an additional {{cvt|22.5|km|mi}} of two-lane Highway 17 to a 400-series freeway. The announcement did not specify costs or timelines, but a new overpass at Calabogie Road opened in August 2023.<ref>{{Cite web |last = Haaima |first = Sherry |date = September 1, 2023 |title = New Highway 17 ramps, overpass at Calabogie Road now open |url = https://www.insideottawavalley.com/news/new-highway-17-ramps-overpass-at-calabogie-road-now-open/article_9c90bdda-28c8-52d6-9895-0ee710b25edb.html |access-date = November 12, 2023 |website = InsideOttawaValley.com |language = en |archive-date = November 12, 2023 |archive-url = https://web.archive.org/web/20231112174525/https://www.insideottawavalley.com/news/new-highway-17-ramps-overpass-at-calabogie-road-now-open/article_9c90bdda-28c8-52d6-9895-0ee710b25edb.html |url-status = live }}</ref>
* Between Thunder Bay and Nipigon, construction to make Highway 11/17 a four-lane divided highway (with at-grade intersections) started in the late 2000s, with completion expected by 2030.

In Manitoba in May 2023, the province announced the launch of a conceptual design study for the twinning of the remaining {{Convert|16|km|mi|adj=on}} two-lane section of Highway 1 west of the Ontario border, plus the immediate construction of a {{Convert|700|m|mi|adj=on}} section to align with four-laning work in Ontario.<ref>{{Cite press release |title = Manitoba Government Announces Next Steps for Twinning Trans-Canada Highway from Falcon Lake to Manitoba–Ontario Border |publisher = Province of Manitoba |url = https://news.gov.mb.ca/news/?archive=&item=59418 |access-date = November 12, 2023 |language = en |archive-date = November 12, 2023 |archive-url = https://web.archive.org/web/20231112182215/https://news.gov.mb.ca/news/?archive=&item=59418 |url-status = live }}</ref>

{{As of|2021|09}}, British Columbia was planning on widening the {{Convert|420|km|mi|-long|adj=mid}} long section of TCH between Kamloops and Alberta to four lanes by 2050. The project goals do not include an eventual freeway conversion, and it is likely that the signalized sections of highway in Kamloops, Salmon Arm, Revelstoke, and Golden will remain. Around {{cvt|16|km}} of four-lane highway were under construction, with {{cvt|6|km}} more planned to start in 2022. Around a quarter of the length of highway between Kamloops and Alberta is{{When|date=May 2024}} now four lanes wide. At the current{{When|date=May 2024}} rate of construction, the project will likely not be completed until the 2070s. However, some of the most difficult sections have been completed, meaning that it may be easier to widen the remaining sections of highway to four lanes. Some of the highway in this section is under the jurisdiction of Parks Canada, specifically the sections through [[Mount Revelstoke National Park|Mount Revelstoke]], [[Glacier National Park (Canada)|Glacier]], and [[Yoho National Park|Yoho]] National Parks, which means that [[Parks Canada]] will have to implement its own four-lane program in order for the provincial government to accomplish its goal.

The City of Edmonton is{{When|date=May 2024}} changing its urban section of Highway 16 (TCH) to a six-lane freeway by replacing all signal lights with overpasses. The route is already largely a freeway, but seven signalized intersections remain. The project is expected to be finished by 2026.<ref>{{Cite web |title = Yellowhead Trail Freeway Conversion |department = Program History |publisher = City of Edmonton |url = https://www.edmonton.ca/projects_plans/yellowhead-trail-public-engagement#:~:text=The%20City%20completed%20a%20strategic%20plan%20for%20the,Council%20to%20designate%20Yellowhead%20Trail%20as%20a%20freeway. |access-date = February 14, 2022 |archive-date = February 14, 2022 |archive-url = https://web.archive.org/web/20220214230223/https://www.edmonton.ca/projects_plans/yellowhead-trail-public-engagement#:~:text=The%20City%20completed%20a%20strategic%20plan%20for%20the,Council%20to%20designate%20Yellowhead%20Trail%20as%20a%20freeway. |url-status = live }}</ref>

{{As of|2021|09}}, British Columbia was planning on widening {{cvt|36|km}} of Highway 1 in the Lower Mainland as part of its Fraser Valley Highway program. The four-lane freeway is over-congested, and many of the overpasses are in poor shape. The project intends to rebuild most of the interchanges and overpasses and widen the highway to six lanes. The first {{cvt|4|km}} of this project opened in 2020, with {{cvt|10|km}} more expected to be complete in 2025.

Apart from the major programs, many smaller-scale projects exist on the highway in order to rehabilitate the aging infrastructure or make minor traffic changes.

Alberta had long term plans to convert both of its Trans-Canada Highway routes to a minimum four-lane freeway standard, but has{{As of?|date=May 2024}} not set a timeline for doing so.{{Clear|left}}
