MONTREAL — More anti-migrant banners have popped up in Quebec, this time in Montreal where many asylum seekers are being temporarily housed.

The banners were posted at various sites either late Sunday or early Monday, including at the Olympic Stadium, where several hundred people who filtered across the border illegally are staying in a makeshift shelter.

Far-right group Atalante Quebec claimed responsibility on Facebook, posting photos of masked members in front of about 10 banners they say were displayed early Monday.

Similar banners carrying the word #REMIGRATION appeared earlier this month in Quebec City, including one on an overpass on a busy thoroughfare.

Olympic Stadium spokesman Cedric Essiminy said today that security guards snapped some photos of a banner before taking it down early Monday.

Montreal police Const. Manuel Couture says the hate-crimes unit will investigate to see if a crime was committed.

Couture says police will also check with their Quebec City counterparts.

Thousands of people seeking asylum have entered Quebec through illegal crossing points over the past several weeks, fuelling heated political debate in the province.

According to the RCMP, at least 3,800 crossed in such fashion in the first two weeks of August alone.

On Sunday, a right-wing group called La Meute held a demonstration to denounce the immigration policies of the federal and Quebec governments.

Before the march, Quebec City police clashed with a contingent of counter-protesters who were there to demonstrate against La Meute.
