The federal government says Canadian evacuees from the Chinese province at the epicentre of the novel coronavirus outbreak will be quarantined for two weeks upon their arrival at Canadian Forces Base Trenton in Ontario.

It made the announcement Sunday night but it didn't provide a timeline for when they'll arrive from the locked-down city of Wuhan, saying it's still awaiting final approval from Chinese authorities.

Global Affairs says the returning individuals both passengers and flight crew will undergo a thorough health screening before boarding, during the flight and upon arrival at the military base.

Until now, the federal government hadn't said whether Canadians who eventually arrive from China would be quarantined.

The number of Canadians who want to flee the Chinese province afflicted by the virus climbed to 325 on Sunday.

Global Affairs says government officials and military personnel are currently en route to Hanoi, Vietnam, and in the process of obtaining visas from the Chinese government to enter Wuhan.

It says the government has chartered a plane to land in Hanoi and then head to Wuhan, where airspace is currently closed, once it gets approval from the Chinese government.

But there's no word yet on when that will happen.
