Flair Airlines just announced last April it would offer low-cost flights from Windsor to Montreal.
Then in October, it announced it would continue the service through the winter. It said the bi-weekly flights would continue until March 2023.
However, the last flight between the two cities will be on February 6.
A statement from Flair Airlines did not explain the decision but said those who booked a seat on those trips would receive a full refund.
In the meantime, a spokesperson for the airline hinted the pause could be temporary, and Flair would soon offer trips to another destination.
"Flair will also announce a new market from Windsor, which we will announce in due course," said the statement. "The airline has made the decision to stop its service to Montreal from Windsor for the time being."
Flair started seasonal flights between Windsor and Tuscon, Arizona and Halifax last summer and said the routes were successful.
Flights to Halifax are available for purchase now, with the first departure scheduled for June.
"Flair is committed to Windsor and travellers in the region," continued the statement. "We look forward to continuing service from Windsor."
