Editing Newmarket, Ontario (section)

== Geography ==
Newmarket's geographical coordinates are 44.05°N, 79.46°W, and its elevation above [[sea level]] is 252&nbsp;m.<ref>{{cite web |title=Newmarket, Canada Page |url=http://www.fallingrain.com/world/CA/08/Newmarket.html |publisher=Falling Rain Software, Ltd. |access-date=13 November 2018}}</ref> It has an area of 38.33&nbsp;km<sup>2</sup>. The town is bounded on the south by [[Aurora, Ontario|Aurora]], on the west by [[King, Ontario|King]], on the north by [[East Gwillimbury]] and on the east by [[Whitchurch–Stouffville]].

The main river in Newmarket is the [[East Holland River]] (known locally simply as "The [[Holland River]]"), and all other streams in the town are tributaries thereto. These include Bogart Creek, a brook that weaves its way into the town from the [[Oak Ridges Moraine]] by way of [[Bogarttown, Ontario|Bogarttown]], emptying into the Holland River in north-central Newmarket; Western creek, another brook rising just west of the town, and reaching the Holland River in the town's north end; Tannery Creek, a stream that joins the Holland River in south Newmarket after flowing through [[Aurora, Ontario|Aurora]]; and a number of other small watercourses.

There are two [[reservoir]]s in Newmarket; Fairy Lake (which is managed by the [[Lake Simcoe Region Conservation Authority]]), a favourite recreational area in the centre of town, is a former [[mill pond]] on the East Holland River; and Bogart Pond, also a former mill pond, is fed and drained by Bogart Creek in Bogarttown. Furthermore, the water level in the reach of the East Holland north of Davis Drive is controlled from an unfinished [[Newmarket Canal]] lock, now used as a [[weir]].

Newmarket also lies south of and above the [[Glacial Lake Algonquin|Algonquin Shoreline]], where elevations suddenly drop off from the gently rolling hills that characterize much of Newmarket to the much flatter, lower land down below in the [[Holland Marsh]].

The land is characterized mainly by [[till|glacial deposits]] from the last [[ice age]], known as "Newmarket Till". The town is underlain mainly by sand and gravel, ground by the [[Ice sheet|icesheets]] that covered the area until about 10,000 years ago. No [[outcrop]]s are to be found anywhere in Newmarket, so deep are the glacial deposits.

===Planning ===
Newmarket is identified as one of the Golden Horseshoe's 25 Urban Growth Centres in Ontario's Places to Grow Growth Plan.<ref name=Placestogrow>{{cite web|url=http://www.newmarket.ca/userfiles/page_attachments/Library/1/3107712_Newmarket_OP___Consolidated_Modifications___2008_04___Regional_Approval.pdf|title= Town of Newmarket 2-2006 Official Plan|date=October 10, 2006|publisher=Town of Newmarket|access-date=August 25, 2008}} {{Dead link|date=September 2010|bot=H3llBot}}</ref>

Four areas of Newmarket have been selected to absorb the majority of planned population growth and accommodate mixed usages on sites well served by transit. These are the Yonge-Davis intersection, Yonge Street (south of Green Lane), the Regional Healthcare Centre ([[Southlake Regional Health Centre]]) and Historic Downtown Centre (surrounding Main Street South).<ref>{{cite web |title=Newmarket Urban Centres Secondary plan |url=https://www.newmarket.ca/LivingHere/Documents/Planning%20Department/Secondary%20Plan/Urban%20Centres%20Secondary%20Plan%20-%20October%2025%202016%20Consolidation.pdf#page=16 |website=Town of Newmarket |access-date=3 August 2019}}</ref> Further construction of big box retail stores in the Yonge Street corridor will not be permitted and the long-term objective of the town is redevelopment or the addition of new buildings to these areas through controlled intensification.<ref>{{cite web |title=Newmarket Urban Centres Secondary plan |url=https://www.newmarket.ca/LivingHere/Documents/Planning%20Department/Secondary%20Plan/Urban%20Centres%20Secondary%20Plan%20-%20October%2025%202016%20Consolidation.pdf#page=21 |website=Town of Newmarket |access-date=3 August 2019}}</ref>

The southwest portion of the town is located in the [[Oak Ridges Moraine]] and is therefore subject to the Ontario Government's [[Greenbelt (Golden Horseshoe)|Greenbelt Legislation]].

=== Climate ===
Newmarket has a [[humid continental climate]] ([[Humid continental climate#Koppen Dfb|Köppen climate classification ''Dfb'']]), with four distinct seasons featuring cold, somewhat snowy winters and warm, humid summers. Precipitation is moderate and consistent in all seasons, although summers are a bit wetter than winter due to the moisture from the Gulf of Mexico and the Great Lakes.
