Deputy Prime Minister Chrystia Freeland says the government is monitoring closely the spread of COVID-19 among health professionals who live in Canada but work in the U.S.
Reports suggest many of the cases in Windsor, Ont., are a result of cross-border travel for essential work.
That's the only reason people are currently allowed to cross the border.
Freeland says stepped up measures have been put in place at the hospitals on the U.S. and Canadian side of the border.
