The Conservatives say voters won't be fooled by the Liberals' promises to change the tone of Canada's immigration policies.
Liberal leader Justin Trudeau said today that if his party forms the government immigration policy will emphasize family reunification over what he says is the Conservative approach of favouring immigrants who could contribute to the economy.
In previous decades, millions of immigrants loyally voted Liberal, but the Harper government has made steady inroads among those voters even as it overhauled the system that brought them to Canada in the first place.
Conservative cabinet minister Jason Kenney, architect of many of the government's immigration changes, says voters won't be swayed by Trudeau's promises.
He says new Canadians are smart and sophisticated and those who came to Canada during the previous Liberal government remember how broken the immigration system was.
