I was wondering when Justin Trudeau would bring his family on the campaign trail. Last week, we caught glimpses of Tom Mulcair's wife, Catherine, and Stephen's Harper's wife, Laureen, who even brought their kids, Ben and Rachel. Today in Ottawa -- it was Trudeau's turn. As he emerged from his bus, he was joined by his wife, Sophie, and their three kids: Xavier, Hadrien, and Ella-Grace. Here's a photo I took:

There's word Harper's family will be joining him for a few weeks because school's not in session, but no sign that Trudeau's will travel with him. He's been going cross-country, and this week I'm told he will go to Montreal, Saskatchewan, Toronto, and New Brunswick.

He started his speech today with reflections about being born in Ottawa and growing up here. "This city is so much more than just what happens in parliament," he said. The rest of his speech sounded very similar to others he's given in the past week -- same lines, even -- but I suppose that's what stump speeches are all about.

I was interested in Trudeau's thoughts about Harper's security announcement today. Harper is vowing to ban travel to terror zones, but hasn't provided a list of what those zones are. Trudeau -- who supported the controversial Bill C51 -- didn't say if he was for or against the proposal, only that he felt it was a distraction from one of the key issues in this campaign: the economy.

I also asked about the Mike Duffy trial starting up on Wednesday. Nigel Wright is expected to be the first witness. Trudeau said the trial will be a reminder of Harper's lack of judgment. But in Quebec City, Harper said, when asked, that he knew nothing about Wright's plan and the $90,000 cheque to pay Duffy's questionable housing claims.

It's unlikely Harper will testify. Crown and Defense haven't indicated he'll take the stand. But this part is interesting: if Harper's asked, he could refuse, and he'd be protected under parliamentary privilege. That privilege exists while Parliament is sitting, and for 40 days after Parliament is dissolved. But because this campaign is so long, privilege will expire before the campaign is over, meaning technically Harper could be called, even though experts I talked to today don't think that's going to happen.

Busy day. I will be reporting from Montreal tomorrow -- following the Trudeau campaign from there.
