The Toronto Raptors are not allowed to play their NBA games in Canada. They will be playing in Florida. The NHL will need to figure out a solution to have a season. I believe the only possible outcome is to setup a Canada based division or just cancel the season.
I suggest All teams play in their home arenas.
Every team plays each other in their division 8 times
Lafleur Division
Calgary, Edmonton, Montreal, Ottawa, Toronto, Winnipeg, Vancouver
Orr Division
NYI, Rangers, Devils, Boston, Philadelphia, Washington, Florida, Tampa
Lemieux Division
Buffalo, Pittsburgh, Columbus, Detroit, Chicago, St. Louis, Carolina, Nashville
Gretzky Division
Dallas, Arizona, Colorado, LA, Anaheim, San Jose, Vegas, Minnesota
Top 4 teams based on winning pct. from each division makes the Stanley Cup playoffs (16 teams)
Proceed to a cup champion with best of 7 series.
