I didn't say anyone was comparing Stantec to Brookfield. I said it's regarded as if it's as nice as Brookfield. However, the two were being compared as they were being built around the same time.
The Toronto comparison is because of the exact reason you said: bigger = more buildings. Thus, Edmonton isn't an actual big city.
On the topic of smaller cities, Winnipeg's infill development is of a much higher calibre than Edmonton. From new high-rises to small-scale apartments and townhouses, there's a level of quality there in terms of design you don't see here. Of course, there's still ugly buildings that have been built here and there in the central city, but on the whole it's nowhere near as prevalent as here. I have no doubt that having an architecture school plus a long legacy of great architecture has helped Winnipeg a lot in this regard, even though its urban planning and policy overall is significantly worse than Edmonton's.
I'm not suggesting there aren't nice buildings being built in Edmonton. There are, but the level of quality in aggregate is still lower than you see in peer cities like Calgary or Ottawa, or even smaller ones like Winnipeg. This city is not a very design conscious one, despite improvements over the past 15 years. We're still letting Langham butcher downtown's best street with buildings that look like they belong on the outskirts of Regina. We still let big box style development happen in Oliver. Our new central library is the laughing stock of the country. Etc. Sure, other cities also have mediocre buildings and not every structure needs to be a gold star, but there should be a base level of decent design on the whole, and that's something this city lacks because it's a city of value engineering. One or two nice buildings doesn't change that. Also, the Winspear Centre expansion is absolutely gold star architecture, I'll agree there, but I'd say the Parks would barely make anyone notice in Vancouver or Toronto. It's not bad architecture, and it'll stand out in Edmonton, but it's not exactly amazing either.
