When the clock struck midnight, all border crossings between Canada and the United States were closed to non-essential travel.
The decision to shut the border without restricting commerce and business was taken to curb the spread of COVD-19.
Air crews, health-care workers and supply chains are considered essential and will be allowed to cross.
Anyone attempting to return to Canada from a holiday will have wiggle room, however, anyone wishing to cross the border for recreation or tourism will be denied entry.
As part of stringent rules to curb the spread of the virus, Prime Minister Trudeau said on Friday migrants will also be returned to the U.S. when they reach the Canadian border.
Recent arrivals in the past few days will not be sent back to America, but they are to remain in isolation for 14-days.
The border crossing changes will remain in place for 30-days.
Public Safety Minister Bill Blair noted that Canadians in “extraordinary circumstances” will be given leeway at the border.
The closure of the border to non-essential travel is an extension of what is already taking place on an international scale.
Canada has shut its borders to most non-citizens looking to enter the country. International flights land at just four airports including Pearson, and travellers arriving in Canada face more intensive screening, and those who exhibit symptoms are not being allowed to board planes to Canada.
