TORONTO -- Major League Baseball has not submitted the required plan to local health authorities that is needed for the Blue Jays to play in Toronto, Ontario's chief medical officer of health said Tuesday.

Dr. David Williams said he has read a MLB proposal but it "doesn't mention anything about travel to Canada at this time."

"If there is some interest in that we would have to get a proposal from them, to see how they would undertake the uniqueness of bringing the team and other teams up here to play how that would work," Williams said.

Anyone entering Canada for nonessential reasons must quarantine for 14 days, and the United States-Canada border remains closed to nonessential travel until at least July 21.

There has been talk the Blue Jays could play games at their training facility in Dunedin, Florida, but the facility was shuttered after one player showed symptoms of possible coronavirus. The virus upended plans of many clubs to resume training at their Florida facilities because of a rise in cases in the state. Most teams intend to work out in their regular-season ballparks, but where the Toronto Blue Jays play remains uncertain.

"The regular-season locale is still a work in progress. That's all we can say at this time," Blue Jays spokesman Richard Griffin said.

Blue Jays president Mark Shapiro said he will not provide an update until MLB's schedule is set.

Dr. Theresa Tam, Canada's chief public health officer, said the federal government has talked to MLB but said any plan to play in Toronto is predicated on a mitigation plan that ensures the safety of Canadians.

"The players have to come together and pose no risk to themselves or the surrounding population," Tam said. "Everything has to be reviewed. There is strict testing and screening and quarantine requirements. Routine testing is part of the mitigation plan. All that has to be evaluated in real time as well and the local health authorizes have to be comfortable."

Federal and local health authorities in Canada have approved a plan for the NHL to play in either Toronto, Edmonton, Alberta, or Vancouver, British Columbia, but the plan does not involve travel back and forth between the U.S. and Canada. That decision last week comes as the NHL enters the advanced stages of selecting its hub cities -- most likely two -- from a list of seven in the U.S. and three in Canada.
