Three votes are set for April 13, including one in a Liberal stronghold in the Toronto riding of University—Rosedale, formerly held by Chrystia Freeland.

Voters in the Quebec riding of Terrebonne will also cast ballots after the Supreme Court of Canada annulled the result of last April’s election, which the Liberals won by one vote.

The court challenge happened after it was revealed that Elections Canada printed the wrong postal code on some mail-in ballots that were not returned.
