Saskatoon police say there is no need to report cars with American licence plates to them.
It went on to say that while entry restrictions do exist, trans-border traffic is allowed for essential purposes.
The tweet concluded with a link to the website of the Canadian Border Services Agency, the federal organization responsible for regulating Canada’s international borders.
A police spokesperson, in an email, said the SPS does not track the number of calls about American vehicles, which is based on anecdotal information.
The spokesperson also said police don’t follow up on calls.
Regina police told Global News they also receive calls and social media messages about cars with American plates.
“We have made it clear that there is no offence to be investigated,” said Elizabeth Popowich, a Regina Police Service spokesperson.
Prime Minister Justin Trudeau announced in March the federal government would close Canada’s border with the United States.
The closure was set to last 30 days but has been extended several times.
Some travellers are still permitted, like those whom the federal government has deemed essential or Americans who are travelling to Alaska.
Yet several Americans have been fined more than $1,000 for visiting Canada.
