Since seat redistribution the West and Ontario gained and has made a need for widespread Quebec support less important for the Conservatives. Harper took 10 seats in 2015. Kevin O'Leary is a Quebec born business tycoon and small C Quebecers can see a person they like in him. Kevin will need to take French lessons and I assume as a Montreal guy he does speak some. He will not need to be fluent or bilingual but show he can address voters in some French. Canada has changed and is changing where the two founding races is a dying concept and bilingualism means something very different to hyphenated new Canadians be they Chinese,  Punjabis or Filipino--and yes they vote too.
