That’s a major aspect of it. In Alberta, most highways inside cities are maintained by the municipality, with some notable exceptions being Deerfoot Trail, Stoney Trail, and Anthony Henday Drive. As a result, Hwy 1A in Calgary has been maintained by the city for quite a while, while in 2013 Hwy 1A was transferred over to the (then) Town of Chestermere. If that didn’t happen before, the transfer likely would have occurred when Chestermere became a city.
The other issue is that with the last round of amalgamations, Calgary and Chestermere city boundaries now touch one another so the route never leaves the jurisdiction of an urban centre. The nature of the corridor is local, so it really doesn’t serve the purpose of a "highway" in the same sense as other routes, such as Hwy 1A west of Calgary.
