CBC identified that Second Sons Canada, led by Jeremy MacKenzie, held its second annual national meeting in early July at Square Butte Hall near Millarville, Alberta, roughly 70 kilometres southwest of Calgary. More than 60 masked members took part in military-style drills including army crawls and marching while wearing shirts reading "old stock enforcer" and chanting a MacKenzie-led, Afghanistan-themed slogan that included the group motto "Our people, our home, our future." Second Sons was formed in 2024 and describes itself as a "men’s nationalist club," but CBC and the Canadian Anti-Hate Network say its leaders have welcomed neo-Nazis, called for mass deportations "at gunpoint," and urged execution of Canadian politicians they deem traitors. CBC located the venue after matching a banner shot over an Okotoks overpass and interior details in videos with photos of Square Butte Hall; the group publishes visuals but often masks participants and omits exact locations. MacKenzie posted on Telegram praising the weekend for "friendly combat sports competition, organizational training, promotions, awards, excellent food and social time." The RCMP told CBC it is aware of Second Sons Canada and is monitoring the group, and local residents described themselves as "shell shocked" to find the training in their community.
