Saturday was also the first full day that the city of Montreal has been under a local state of emergency. Montreal Mayor Valerie Planted declared the emergency Friday at 4 p.m. at the request of Quebec's public health department.

The city's public health department was expected to announce new city-wide restrictions and measures Saturday to try to stem the spread of COVID-19, but instead announced that those new measures will be made public Sunday.

Quebec Premier Francois Legault was replaced by Deputy Premier and Minister of Public Security Genevieve Guilbault at the province's daily COVID-19 update on Saturday.

Guilbault announced that Quebec is restricting all non-essential travel to and from eight of Quebec's regions and that provincial police will be deployed to ensure those restrictions are being followed. Those regions are:

Bas-Saint-Laurent

Abitibi-Témiscamingue

Côte-Nord

Nord-du-Québec

Saguenay–Lac-Saint-Jean

Gaspésie–Îles-de-la-Madeleine

Nunavik

Cree Territory of James Bay

Guilbault also announced that the Surete de Quebec is setting up checkpoints on highways at Quebec towns near the U.S border in order to inform those returning home about the quarantine restrictions imposed by the government.
