Hamilton's mayor has sent letters to local businesses, asking them to be aware of an anti-immigration group advertising a conference in the area. On Aug. 4, several Hamilton groups, including the Hamilton Anti-Racism Resource Centre (HARRC) and Hamilton Centre for Civic Inclusion, signed an open letter urging businesses and institutions not to rent space to Dominion Society. Dominion Society also promotes an agenda that includes the mass deportation of people including temporary foreign workers, permanent residents and people born in Canada to non-Canadian citizens. Horwath's letter notes the Canadian Anti-Hate Network has identified Dominion Society as part of a growing white-nationalist movement in Canada. The business posted to Instagram over the weekend, saying "we are glad the City is taking this threat seriously enough to notify local businesses."
