Speed limits in Canada

[5] The highest posted speed limit in the country is 120 km/h (75 mph) and can be found only on the Coquihalla Highway.

This table contains the statutory maximum speed limits, in kilometres per hour, on roads in each category.

[12] Formerly, British Columbia's Okanagan Connector and Highway 19 also possessed 120 km/h limits, but were reduced to 110 km/h in 2018 to address an increase in collisions.

In Ontario, speeding fines double in areas identified as "Community Safety Zones".

[14] Since 2009 in both Ontario[15] and Québec,[16] trucks must be equipped with devices to electronically limit their speed to 105 km/h (65 mph).

The report recommended increasing speed limits on multi-lane limited-access highways constructed to high design standards from 110 km/h to 120 km/h.

The practice considers the 85th percentile speed, road geometry, roadside development, and crash history."

[22] Ontario's first provincial legislation governing automobile use came into effect in 1903, which included a 15 mph (24 km/h) speed limit.

In 1977, highways started using the metric system, with speeds being increased slightly to a maximum ranging from 80 to 100 km/h (50 to 62 mph).

[28] On September 26, 2019, speed limits were raised in a two-year trial to 110 km/h (68 mph) from 100 km/h (62 mph) as part of a pilot across a 90 km (56 mi) stretch of Highway 402 from London to Sarnia, a 32 km (20 mi) stretch of the Queen Elizabeth Way from Hamilton to St. Catharines, and a 102 km (63 mi) stretch of Highway 417 from Ottawa to the Ontario / Québec border.

[35][36] On October 2, 2024, Doug Ford mentioned in a news conference that he had directed Transportation Minister Prabmeet Sarkaria to explore raising the speed limit to 110 km/h (68 mph) on all remaining 400-series highway sections "where it is safe to do so".
