The NHL could face another hurdle if the league decides to continue the 2019-20 season in the near future -- getting non-Canadian resident players across the border to join their teams.

Prime Minister Justin Trudeau said Sunday that players would -- at a minimum -- need to follow quarantine protocols if they were to arrive in Canada while the border remains closed due to the pandemic.

"I think it's a question we'll have to look into,'' Trudeau said. "Certainly at a strict minimum, anyone who arrives from another country will have to follow all the rules of quarantine in an extremely strict manner, but we're not there yet in our discussions with the NHL.''

"We recognize that it's a possibility, but it depends on an enormous amount of things, and I don't want to speculate on this until there's more discussion," he said.
