Voters in four ridings across the country, including that of former Public Services Minister Judy Foote, will head to the polls for by-elections on Dec. 11.
Prime Minister Justin Trudeau announced the date of the federal by-elections for the Newfoundland and Labrador riding of Bonavista-Burin-Trinity, the British Columbia riding of South Surrey-White Rock, Saskatchewan's Battlefords-Lloydminster and Ontario's Scarborough-Agincourt on Sunday.
Foote stepped down as a cabinet minister in August and as the MP for Bonavista-Burin-Trinity in September after learning that her two adult daughters were at risk of breast cancer, which she has survived twice.
And the B.C. riding became vacant when former-Conservative MP Dianne Watts stepped down to run for the provincial Liberal leadership.
The Saskatchewan riding is up for grabs after long-serving Conservative MP Gerry Ritz retired from federal politics in August.
The death of Liberal MP Arnold Chan prompted the Toronto-area by-election.
