Prime Minister Justin Trudeau will spend Wednesday in Calgary, drumming up Liberal support for two byelection candidates.
The prime minister will visit Haley Brown in the riding of Calgary-Midnapore, and Scott Forsyth in Calgary-Heritage.
The seats became vacant with the departures of former prime minister Stephen Harper and former cabinet minister Jason Kenney.
Trudeau will join Brown and Forsyth at a Liberal rally Wednesday night.
Not to be outdone, interim Conservative leader Rona Ambrose will also be campaigning in Calgary Wednesday, to bolster support for the Tory candidates, Bob Benzen (Calgary-Heritage) and Stephanie Kusie (Calgary-Midnapore).
The byelections will be held April 3.
