I came across this web site yesterday that is kind of interesting, it's called Stadium Journey.
These guys have people across North America and parts of Europe that write reviews of stadiums and arenas.
Here is the link to Ivor Wynne:
Ivor Wynne faired ok. Out of 5, Ivor Wynne scored 3.3 for the stadium but only a 2.4 for the crowd. It was the lowest ranking of all the CFL stadiums.
Six of the CFL stadiums are in it, the only exceptions are Saskatchewan and Winnipeg.
