He will also unveil his cabinet, officially bringing the Parti Québécois back to power after more than a decade.
The sovereigntist party won 59 seats in the Oct. 5 provincial election, falling short of the 64 needed for a majority government.

The PQ has requested recounts in two ridings where its candidates finished second, potentially bringing it closer to a majority.
The party’s elected representatives were sworn in last week, and took an oath of allegiance to the people of Quebec rather than the King.
The legislature dropped the requirement to swear allegiance to the monarchy in 2022 after St-Pierre Plamondon refused to take the oath.
If they did not swear allegiance to the head of state, they should not be allowed to hold office.
