3. West Village -- Greyhound Depot and GSL Chev-City
This is the area directly west of 14th St and bound by the two halves of Bow Trail. The city owns most, if not all, of this land already and has long-term plans to redevelop it as the West Village.
It would be very difficult to put a football stadium into this space with a North-South field orientation. The stadium really only fits if the field were run East-West. The North-South orientation is preferred because it doesn't force one team to play into the sun during the game. Ivor Wynn Stadium in Hamilton is currently the only E-W oriented stadium in the CFL (McMahon is angled slightly to the NW and Taylor Field is angled even more to the NW), but even it is rumored to be getting re-aligned during its reconstruction next year. The stadium in Ottawa also has an E-W orientation, which won't be changed when it re-opens in the future.
3. West Village -- Greyhound, GSL, Renfrew Chrysler
This is the same West Village area, but expanded to include the space currently occupied by Renfrew Chrysler. This would allow for the football stadium to go on the Renfrew space with a field orientation similar to McMahon's.
This would be a drastic change to the City's West Village plans (

The land in this area is badly contaminated because there was a wood treatment plant there for decades, then the car dealerships moved in. Cleaning it up to the point where it's safe for people to live might be impossible, and even if it isn't, it will be extremely expensive.
From a transportation point of view, it's well located. The new Sunalta C-Train station is right there, and Crowchild and 14th St are both nearby.
