The new coronavirus has spread across Canada with a total of 313 cases confirmed on March 15 in its 10 provinces, the chief public health officer said.
Atlantic coast provinces were the last to be hit. Major metropolitan centres — Toronto, Montreal and Vancouver — remain the most affected.

After a meeting of Prime Minister Justin Trudeau's cabinet, ministers said to expect more actions to be announced today.
Canada has tested nearly 25,000 people — among the highest per capita rates in the world. The number of positive test results jumped from a few dozen just last week, including one death.
"Most of the cases (in Canada) have been linked to travel," Tam said, "but that could change very quickly."

"We've taken some very strong measures, and we are not taking anything off the table, we are looking daily at next steps that we might take, or we shouldn't take," Trudeau told broadcaster CTV in an interview from his Ottawa home where he and his family are self-isolating after his wife Sophie tested positive for the virus.
The prime minister added, "Sophie's got a headache right now and feeling a little under the weather, but it is not worse than what would be a bad cold," he said. "Of course we're all being very careful."
Tam noted that it was important for every country to "contain the outbreak within their own setting," but added that "countries that enacted travel bans have not been able to keep out this particular virus."
In fact, she said, some countries that "have been impacted the most have actually been the ones with the most stringent travel and border measures."
