President Donald Trump is changing not just American politics. Canadians are increasingly concerned that the presidents nativist and anti-Muslim rhetoric is emboldening hate groups in a Canada, which has long prided itself on multiculturalism and tolerance.

This weekend, far-right activists rallied against asylum seekers on the border between Quebec and New York as riot police and counterprotesters gathered nearby. Members of the Three Percent a militia founded in the United States that has recently spread to every Canadian province were at the event. Its just one of the many far-right groups that have started chapters in the Great White North in the months since Trumps election.

After he was elected, obviously the U.S. saw a spike in hate-inspired activity. But Canada did too, said Ryan Scrivens, a fellow at Concordia University who specializes in tracking far-right groups. He refers to the phenomenon as the Trump effect.

When the U.S sneezes, Canada catches a cold, he added, repeating the adage.

In Toronto hate crimes went up by almost a third from 2016 to 2017, with Muslims and Jews the primary targets. In Quebec City, reported hate crimes last year targeting Muslims doubled the 2016 total.

Two mass killings in the last 18 months have added to Canadians fears of violent extremism. Both attacks were highly unusual for a country that has mostly been spared the kind of deadly violence that has become all too familiar in the United States.

Last month, a 25-year-old man drove a truck into a crowd of pedestrians on a busy Toronto street, killing 10 people. A post on the suspects Facebook account called for a rebellion by incels, or involuntary celibates, who are part of the far-right manosphere and often espouse violent misogynistic rhetoric. The post celebrated Elliot Rodger, an American who killed six people after writing a hate-filled manifesto against women.

In January last year, a man attacked worshippers at a Quebec City mosque, killing six Muslim men. Before the attack, the shooter obsessed over far-right Islamophobia, American mass killers and Trump.

Trumps rhetoric has galvanized Canadian-based white supremacist ideologies, identities, movements and practices, Scrivens and three fellow researchers argue in a forthcoming article in the Journal of Hate Studies.

Canada now has as many as 130 active right-wing extremist groups, according to researchers about a 30 percent increase since the last assessment in 2015.
