NHL believes all seven of its Canadian teams can start the season playing out of their home arenas.NHL deputy commissioner Bill Daly said Thursday the league believes it is clear to play in Canada during the second wave of the COVID-19 pandemic after discussions over the past 24 hours with provincial health authorities.“On the basis of our discussions (with provincial health authorities) in the past week, as well as our exchange of correspondence over the last 24 hours, we believe we are aligned and in agreement on the conditions on which each of our Canadian franchises can begin play in their own buildings for the start of the 2020-21 NHL season,” Daly said.
