Many of Calgary’s residential streets will soon have lower speed limits.
In a vote of 10 to four on February 1, Calgary city council members decided in favour of reducing speed limits to 40 km/h on residential streets, lowered from the current default of 50 km/h.
Collector roads (busier streets that connect neighbourhoods to larger roadways) will be 50 km/h.

This change will take effect on May 31, and it will affect the unposted speed limit in the city, meaning that if there is no sign posted on a residential road, you can assume the limit is 40 km/h.
There will be no changes to the limit on higher classification roads like Deerfoot Trail, Bow Trail, or Anderson Road. Playground zone speeds will also remain the same.
To determine if it is safe for a collector road to have a 40 km/h speed limit, there are a number of factors that the City of Calgary considers.
These factors include how long the road is, if traffic calming (speed humps or cushions) has been installed on the road, if the average speed of drivers is consistently below the current speed limit, whether the road has low traffic volume, and if the road is part of a bus route.
The following maps show what the speeds will be on roads in the city’s 14 wards as of May 31.
