Coronavirus updates from Canada and around the world on Sunday.

More than 20,000 deaths in Canada due to COVID-19. 

On Sunday, more than 20,000 people died in Canada due to COVID-19  . Many flights were halted in order to limit further spread of the virus.

The number was discovered after Quebec and Ontario reported 31 and 43 new fatalities, respectively, due to the virus. The number increased again by four later in the day when Manitoba informed four new deaths.

Dr. Theresa Tam, Canada's chief public health officer, has said the number of new daily cases is trending downward.

But she's also warned that it's not yet the time to get rid off widespread public health restrictions, saying the virus is still spreading rapidly across parts of the country.

On Sunday, Tam in a statement urged Canadians to stick to the public health rules so as to compliment to the efforts of front-line health workers, who she said are at risk of psychological distress and burnout due to stress, long hours and the difficult medical decisions they have to make.

"In the face of these challenges, front-line health workers may feel tremendous personal, organizational or societal pressure to be superheroes — to not appear vulnerable, tired, worn down or weak," she wrote. "All of these pressures may prevent them from seeking the care, treatment and supports they need for their own mental health."

Canada are in Ontario and Quebec together come under the most affected area with nearly 16,000 fatalities. According to the Ontario Ministry of Health COVID-19 data page, 1,658 people with COVID-19 have died in January 2021, proving it to be the province's deadliest month of the pandemic so far.

Starting from the death toll from March 9,2020 its number has touched the graph of  10,000 deaths  on October,27.
