OTTAWA -- The federal government is extending travel restrictions by one month to limit the spread of COVID-19.

Public Safety Minister Bill Blair said Friday on Twitter that existing restrictions on international travel to Canada would be extended to Sept. 30.

Blair says Canadian citizens and permanent residents who are returning home to Canada will continue to be subjected to strict quarantine measures.

Travellers coming to Canada will still be asked whether they have a cough, fever or are having difficulty breathing.

New arrivals are required to quarantine for 14 days if they don't have symptoms, or isolate for 14 days if they do.

Canada has taken steps to stem the flow of foreign nationals into the country by restricting discretionary travel, including for tourism, recreation and entertainment.
