That Calgary shot is unbelievable. It is extremely dramatic, but I don't remember a day recently when it was that smoggy, but this is clearly a super recent photo. Amazing, thanks for posting.
And regarding Calgary and Edmonton having a "smattering" of historic buildings, I wouldn't really call the 4 or 5 straight blocks of Stephen Avenue between Old City Hall and Bankers Hall to be a "smattering", nor the 5 straight blocks of historic structures between 6 Avenue and 11 Avenue on First Street. Outside of those significant corridors with mostly century+ old buildings, yeah it's a smattering, but considering one of those two areas is a national historic site due to its historic character, it should be recognized. And as for Edmonton, while yes its downtown has only retained a few (but a couple remarkable) historic structures, Whyte Avenue's 7 or so straight blocks of mostly historic structures (some of which quite uniquely styled by Canadian standards) is also not to be overlooked.

The scale between the Winnipeg/Vancouver and Calgary/Edmonton buildings is the main difference, not the number.
