The Conservative Party targeted Mount Royal in the 2015 election, with Prime Minister Stephen Harper launching his party's campaign in Mount Royal. Housefather ran a vigorous door-to-door campaign, and managed to assemble support from a wide variety of communities within the riding as well as the majority of elected officials at the municipal and school board election. Housefather and the NDP candidate debated four times in the riding, with the Conservative candidate participating in two of the debates and refusing two. However, Housefather debated against Conservative candidate Robert Libman on CTV and Radio Shalom, and all three candidates debated on CJAD.
