We were actually pretty close to not getting a permanent track for the PanAm games next summer, the original plan was a temp track for 1/10th the cost. The fear was because Montreal had a permanent track for the 76 games which is now I zoo I believe, a perm track would go unused. Thankfully the powers that be say that a permanent track had more to offer long term, and actually was largely paid for with fund raising.
The new soccer stadium is going to be an already needed CFL stadium (or NFL if/when we bring the bills over
)
I don't think there is ever not huge opposition to hosting the games.
