Hey your from Canada.. why didn't they do that for cfl stadiums too? I've been in Regina for a winter game...it was awful lol.
Cash. I think for the majority of CFL teams, the cash just wasn't there to build enclosed. Like, you wanna build a 1.5 BB dollar stadium in Hamilton Ontario? Not gonna happen.
Shit - here in Calgary - McMahon stadium is circa 1960. The flames are getting a new stadium here, and I 'thought' the Stampeders were playing as part of it - but my google searching is not conclusive on this one. Even if they do get to play in the new digs - HOCKEY, not CFL is the reason our new stadium is getting built.
The CFL is on life support from what I can tell. I'll have to google it, but I 'think' BC might be the only covered stadium. Without TSN (canadian sports channel) revenue - I'm quite sure the league would be bankrupt. The Toronto Argonauts used to play in the covered Rogers Centre - but they don't anymore. I think some games here only had like 2000 people or less attending at best this year.
To your point: There are a breed of Canadian CFL fans that pride themselves on being 'hardy'. Like -30 is no big deal. I'm not one of those people. 0C/32F is about the limit for me. They take their heated seating pads, and booze-filled thermoses that are slightly flavoured with hot chocolate and tough it out (not that there's anything wrong with that). So, generally whether a venue is 'covered' or uncovered here doesn't seem to be the rate controlling step for attendance.
We're nuts. The Hockey Classic thing up here that's purposely outdoors is some huge big event. Meh. I don't wanna freeze to death out there.
And if you've been in Regina in the winter - well, football might not be your biggest problem

Wearing a hollowed out watermelon on your head at -30 degrees would be a problem
