The group Canadian Muslims For Peace say they are horrified by the recent attacks in Paris and the radicalization of some young men in this country.
But they also say they pay a price for others' crimes.
"Now in the era of social media, every action is exponential. One thing that one person does is rebounded, retweeted, reblogged, rehashtagged around the world," organizer Aneesa Mustafa told CBC News.
Case in point — the federal government's new security legislation unveiled yesterday in Richmond Hill. Some Muslims at today's rally fear Bill C-51 could unfairly target them because of their faith.
"It seems like everything that happens becomes an excuse for increased limitations on our human rights and our civil liberties and increasing surveillance on a small community in Canada," said El-Farouk Khaki, a Toronto immigration lawyer.
Canadian Muslims For Peace also held rallies today in Ottawa, Kingston and London.
