The government, which has faced criticism over ongoing pandemic restrictions, may bring back the vaccine mandate if a new variant of the virus is discovered, the report added.
Canada's federal COVID curbs have included barring unvaccinated people from travelling on airplanes and vaccine mandates for federal civil servants.
Last week the country suspended random COVID testing at all its airports for the rest of June to ease long waiting times that travellers have been facing.
The government did not respond to a Reuters request for comment.
