Federal restrictions on COVID-19 at the border are being extended to at least June 30, Health Canada and the Public Health Agency of Canada announced on Tuesday.
The federal government will continue to require foreign tourists to provide proof of being fully vaccinated.
Canadian citizens or unvaccinated permanent residents must also show proof of a molecular test of COVID-19 done before entering Canada and being quarantined for 14 days.
All travelers coming to Canada, regardless of their nationality, must also continue to submit their health information through the ArriveCAN app before entering.
The announcement comes a day after a Conservative motion calling on the federal government to lift all remaining travel restrictions on COVID-19 was defeated in the House of Commons.
The Canada Airports Council has blamed the massive nationwide customs delays on pandemic measures and staff shortages, which have led to alignments while airports cannot physically contain them in some cases.
Transport Minister Omar Alghabra says discussions on balancing public health measures with the economy are still ongoing.
