His comments come as the country’s two most populous provinces continue to post their highest number of daily cases in months, while placing greater restrictions on virus hotspots.
Quebec reported 1,107 new cases of COVID-19 on Saturday, while Ontario reported 653.

New Brunswick also reported a new case of the virus today which local health officials say is linked to displacement outside the Atlantic bubble.
