Conservative Leader Stephen Harper should be “embarrassed” to do a rally with Doug and Rob Ford, Liberal Leader Justin Trudeau said at a campaign stop in Montreal on Thursday.

“Stephen Harper should be embarrassed that he’s having to count on the support of Rob Ford for his re-election. You know, there’s a lot of people talking in the news these days about the hypocrisy of the Fords and their drugs problems and Mr. Harper and his position on that,” he said.

“But that’s not really the issue — as serious as it is — that strikes me most. What bothers me most is the misogyny. The Ford brothers should have no place on a national campaign stage, much less hosting a prime minister at an event this weekend. That’s just completely irresponsible of the prime minister.”

Trudeau didn’t clarify what misogyny he was referring to. Though there are a few possibilities, at least as far as Rob Ford is concerned. The Toronto Star enumerated them in a May 2014 editorial.

Not long after Trudeau’s remarks, Rob Ford took to Twitter to defend his involvement and to criticize the Liberal leader.

As usual, I’m focusing on policy, not personal matters. Trudeau will cost the typical Canadian family THOUSANDS of dollars out of pocket — Rob Ford (@TorontoRobFord) October 15, 2015

47% of traditional Liberal voters vote for the Fords. They support us, and we support them by committing to keeping their taxes low #elxn42 — Rob Ford (@TorontoRobFord) October 15, 2015

Though the prime minister had some trouble saying their names on Wednesday — referring to them as “those individuals” and “that family” — Doug Ford confirmed Wednesday morning that he and his brother helped the Conservative Party organize a rally this Saturday evening at the Toronto Congress Centre Etobicoke.

“Man, we’re gonna show ’em what a real rally is about,” Doug Ford told CP24’s Stephen LeDrew.

On Wednesday, Maclean’s also published an excerpt from a new book by Mark Towhey, Rob Ford’s former chief of staff.

They had to edit Mayor Rob Ford: Uncontrollable: How I Tried to Help the World’s Most Notorious Mayor to “remove a handful of lines that contained material not appropriate for Maclean’s.”
