Canada Border Services will introduce more screening measures at airports for Canadians returning from abroad.

On Monday, Justin Trudeau announced that Canada will be closing its borders to virtually all non-residents as of Wednesday, March 18. In addition, international flights will only land in Montreal, Calgary, Toronto and Vancouver.

All travellers entering the country will be subject to "new enhanced screening measures" at all airports.

Canada Border Services will ask all travellers if they have a cough, fever or difficulty breathing.

The agency will also ask all arrivals to self-isolate for 14 days to prevent further spread of COVID-19.

Before Trudeau's announcement, many Canadians felt that the agency wasn't doing enough compared to other countries.

I just passed thru 4 international airports in the last 36hrs and Canada was the worse, just questions and hand out of information sheet, where are the body temperature scan like Singapore and Indonesia??? They are way more prepared then you guys ! #canadafail

And others pointed out that touch screens on inspection kiosks aren't exactly sanitary.

In theory fine, but in practice: a) touch screens aren't sanitized between use b) very often the touch screen don't work or confuse people and staff have to help them - that's close contact and enables transmission

Mayor of Montreal Valérie Plante even announced that Montreal's public health department will be deploying dozens of employees to intercept returning Canadians at the airport.

Travellers will be asked to self-isolate and take their temperature twice a day for two weeks.

Trudeau's decision to close Canada's border and enhance screening measures comes in the wake of Canada announcing over 345 cases of coronavirus across the country.
