There will be stepped-up enforcement and surveillance at most Canadian land borders in the coming weeks, the sources add.
By mutual agreement, the US-Canada border has been closed to all non-essential traffic since March.
The sources spoke on the condition of anonymity, as they are not authorized to speak publicly on the matter. Canadian Prime Minister Justin Trudeau is expected to formally announce the decision later this week.
CNN has reached out to US officials for comment.
President Trump and Prime Justin Minister Trudeau discussed the matter briefly during a phone call Monday morning, according to Trudeau’s office.
Also on Monday, Trudeau said Canada recognizes that the US coronavirus pandemic is a “complex” situation.
Truck drivers, healthcare workers, flight crews and others including most recently sports professionals, are currently exempt from Canada’s mandatory 14-day quarantine.
According to one poll, a large majority of Canadians say the US-Canada border should remain closed for the foreseeable future.
