Legault thankful Ottawa will shut border as COVID-19 cases climb in Quebec

• Quebec will provide $573 per week for workers in isolation who don't qualify for other income compensation measures.

• Call 1-877-644-4545 if you think you have COVID-19 symptoms instead of 811.

• 50 confirmed cases in Quebec on Monday, up from 39 on Sunday.

• Increased screening coming at Montreal's Trudeau airport.

• The first COVID-19 patient detected in Montreal has recovered.

• Montreal public health says the likelihood there is already community transmission is "probable."

• The STM is maintaining regular bus and Metro service with increased cleaning procedures.

• Legault called on Quebecers to donate blood, to boost provincial supplies.

As the number of confirmed COVID-19 cases continues to rise in Quebec, Premier Franois Legault welcomed the federal government's decision to close Canada's borders to foreign travellers.

Legault has been pushing for the measure since last week, but Prime Minister Justin Trudeau was initially reluctant to take that step.

Both the Quebec government and the City of Montreal were frustrated by the lax screening and scant information available for travellers arriving at Trudeau airport, a facility that falls under federal jurisdiction.

In Quebec, as in other parts of the country, there have been numerous reports of travellers arriving at airports and receiving no instruction about isolation guidelines currently in place by public health officials.

On Monday morning, Montreal Mayor Valrie Plante took the unusual step of deploying municipal employees at the airport.

Plante said it wasn't a matter of "throwing stones" at the federal government, but she felt there was a need "to strengthen the level of awareness of users about the seriousness and importance of respecting the public health recommendations."

The city workers have been tasked with informing incoming travellers they must stay home for 14 days, take their temperature twice a day and record any symptoms they start showing.

"Each time a traveller does not self-isolate, it's a breach that the virus can get through," said Dr. Mylne Drouin, Montreal's public health director.

The federal government appeared annoyed by the move. Treasury Board President Jean-Yves Duclos gave an interview to a Montreal radio station, saying it was his government's responsibility to improve the situation at airports.

Finally, early Monday afternoon, Trudeau announced the border would close on Wednesday, with exceptions for American citizens, air crew, diplomats and immediate family members of citizens.

"I'm very happy. I'm satisfied," Legault said after Trudeau's announcement.

More closures as confirmed cases rise to 50

The Quebec government, meanwhile, continued to add to the long list of facilities it has closed in order to limit the spread of COVID-19.

Youth centres and outdoor activity centres will shut their doors, and the government is actively discouraging places of worship from holding marriages or funerals.

Over the weekend, the government ordered bars, clubs, concert halls, movie theatres, ski hills, amusement parks, spas and saunas to shut down. Fitness classes like yoga and spinning have also been cancelled.

The number of confirmed COVID-19 cases stands at 50 in Quebec. But with 3,073 test results pending, the number of confirmed cases likely continue to rise, Legault said.

There has not yet been a case of community transmission detected in Quebec, though public health officials believe it is simply a matter of time before that happens.

The virus has an incubation period of, on average, seven days before symptoms manifest. The symptoms escalate gradually for another seven days, on average, at which point a patient will be prompted to seek a test.

"That suggests the numbers we're seeing today actually reflect disease that was transmitted two weeks ago," said Dr. Matthew Oughton, a physician in the infectious diseases division at the Jewish General Hospital.

Health Minister Danielle McCann said the province is in the process of increasing its testing capacity. It is currently processing around 1,600 tests daily; the goal is to get that number up to 6,000 as soon as possible.

The priority for public health officials remains testing people who have travelled abroad and have symptoms of COVID-19, such as a fever, cough or difficulty breathing.

"But it's clear we'll be testing more people ... when we have that capacity," Quebec's public health director, Horacio Arruda, said Monday.
