Supreme Court nullifies Liberal single-vote election win in Montreal-area riding | CBC News

The Supreme Court of Canada annulled the results of a closely contested riding from last spring's election, triggering a new byelection for the Montreal-area riding of Terrebonne. The electoral district was initially declared for the Bloc Québécois, but a judicial recount later found the Liberals had won the seat by one vote. The ruling follows a misprint on a mail-in ballot return envelope, which led to a voter's ballot being returned and not counted. The Supreme Court's decision marks the first time a court has annulled the results of an election in Canada's history.
