“Alberta is officially rat-free and strictly enforces it”
TRUE! Norway rats are designated as pests, and it is illegal to keep them as pets. Alberta is the largest inhabited rat-free area in the world.
Alberta launched its rat control program in 1950 when Norway rats were advancing westward across Canada. The province established a "rat control zone" along its eastern border and has maintained it ever since. Today, Alberta maintains a buffer zone along the Saskatchewan border, employs pest control officers who respond to rat sightings, prohibits pet rats, and conducts public education campaigns. The occasional rat does make it into Alberta (usually via shipments), but the province responds aggressively, and finding and reporting a rat is taken seriously.
Where the story gets it wrong
Alberta is not literally free of every single rat — occasional infestations are detected and rapidly eradicated along the eastern border with Saskatchewan, where the province maintains a 600-km Rat Control Zone. The ban itself applies specifically to Norway rats, not all rodent species.
Under Alberta's Agricultural Pests Act (RSA 2000, c A-8) and the Pest and Nuisance Control Regulation (Alberta Regulation 184/2001), Norway rats (Rattus norvegicus) are declared a pest. Section 11 of the regulation prohibits any person from keeping, selling, or purchasing live rats without a ministerial permit, which is only available to research facilities, zoos, or inspectors meeting minimum standards set by the Minister. Landowners and municipalities are required to destroy and prevent the establishment of rats on their property.
