Sorry I should've specified, that would make sense. But this structure is in the parking lot along Crowchild, east of McMahon. It basically looks like a huge metal carport, like 3 storeys high. It's probably for the Grey Cup but it just looked really bizarre when I was driving by.They are adding temporary suites at the south endzone for Grey Cup. I haven't been by but I THINK that is probably what your seeing.
