GC Probabilities for the next 2 or 3 years:
#1 Ottawa - as stated above, ready willing and deserving
#1A Hamilton- if they have their endzone seating plan ready, go for it, same reasons as Ottawa, Grey Cup in the Hammer would be amazing.
Edmonton - always do a great job, all facilities in place, their spot in the rotation is coming around again soon.
Calgary - worthy hosts, all arguments similar to Edmonton, but MIGHT (just a guess on my part) be using Bob Young/Ivor Wynne strategy of claiming a new stadium is needed to host a Grey Cup, so hosting one at McMahon would destroy that argument and weaken their voice for a new stadium.
Toronto - so long as they can sort out the stadium issues, ideally at BMO if they can fit everyone in, if not would the Dome be available at a reasonable price? But I also don't care for Toronto getting it every 4 years just because they're Toronto when everyone else has to wait 10. Sure, bigger cities can have it a little more often but how about a minimum 5 or 6 year gap?
Regina - new stadium so most likely in the 2018-2020 range.
BC - nothing against them but hosted twice in last 4 years, so spread it around.
Winnipeg - hosting this year obviously.
Montreal - would LOVE to go back there, but McGill is too small and Olympique is now apparently closed in the winter so there is no place to play.
Fort McMurray! 8)
