OTTAWA - Leader Justin Trudeau says a Liberal government would repeal the Conservative government's two-tier citizenship law, and ensure a strong and united Canada where all citizens are treated equally.

Trudeau told Canada's largest Islamic conference on Saturday that "Liberals believe in a Canada that is united -- strong not in spite of its differences, but precisely because of them."

Trudeau told the gathering in Mississauga, Ont. that under Stephen Harper, Canadians are being encouraged to be fearful of one another, and there has been a decline in family reunification, refugees, and citizenship applicants.

He said Harper and NDP Leader Tom Mulcair are playing the politics of division and fear, while his party will ensure a more equal society.

Harper spoke to the group Friday, mentioning the issue of homegrown terrorism and praising Muslim leaders for their efforts to curb youth radicalization.

Harper had no public campaign events planned this weekend and NDP Leader Tom Mulcair is off the campaign trail until Sunday.
