The federal riding of Toronto-St. Paul's is holding a by-election on 24 June. The seat was left vacant in January by the resignation of Carolyn Bennett of the Liberal Party of Canada, who had held the seat for the Liberals since 1997.

The by-election is happening during a polling slump for the Liberals (Canada338 has Toronto-St. Paul's as Liberal "leaning" rather than "likely" or "safe") and may be a political test for Justin Trudeau.

Electoral reform activists, as part of the Long Ballot Initiative, have pushed to make the ballot the longest in Canadian history, with 77 candidates having registered.

Will the Liberal Party of Canada win the June 24th federal by-election for Toronto-St. Paul's?
