Thirty of 32 NHL teams will be able to operate at 100 percent capacity this season, per an NHL memo regarding teams' COVID-19 policies for the 2021-22 season. The lone exceptions are the Bell Centre (home of the Montreal Canadiens) and Rogers Arena (the Vancouver Canucks' home arena).
Per Eric Engels of Sportsnet, 10 of 32 arenas will require proof of vaccination for entry. Eight arenas will need proof of vaccination or a negative COVID-19 test.
The remaining 14 teams are not listed as requiring proof, but as ESPN's Greg Wyshynski noted, some franchises have not yet solidified their COVID-19 policies for this season.
