SkydivePilot: Football has traditionally been played outdoors. Even large cities are moving to single-purpose open-air stadiums, which are cheaper to build and operate. If you don't like the weather, stay home.
Putting the stadium at Evraz Place is an interesting idea. Most likely it'd be on the land between the Brandt Centre and Elphinstone Street. Wonder if they'd keep the current northwest/southeast orientation of the field, or change it? They'd definitely be wise to include generous space in the end zones for additional Grey Cup seating. Though I don't agree that the new stadium needs to have 35,000 seats. Even in good years, the 'Riders aren't normally going to need more than 33,000 seats, because there's just not
that much demand.
An underpass at the CPR crossing at Elphinstone would be much appreciated, think the city could swing it?
As for the CPR land, it might be an OK place for some condo towers aimed at single young professionals. That makes for an attractive client base for the nightlife right across the street. There would probably be some green space near the CPR mainline for an eventual walkway leading to Evraz Place.
This is starting to sound like it might be a good idea if planned and executed properly.
