It's a small trend, but Marda Loop is quite weird in this retail conversion thing by Calgary standards.
Here's a streetview from back in 2007, almost 20 years ago(!), notice the whole block had already been converted to retail. I don't know the local history enough to guess when they were first converted but probably a while before that.
I am also curious to understand the unique nature of 33/34 as twin main street type roads, it's pretty unusual. The development of Crowchild, the semi-gating of Upper Mount Royal as a wealthy enclave, the redevelopment of the military base - all played a role here likely. We don't see many of these "which street is the main street?" twin corridor things very often.
