Fact check
“For more than seven decades, residents of Alberta have been officially free of rats.”
Reasoning
The Guardian articles report that Alberta’s official position is that the province has been rat‑free since the Rat Control Program was established in 1950, which is over 70 years ago. The articles also note that the province maintains reporting mechanisms and that most reports are not actual rats, though occasional exceptions are acknowledged. This directly supports the claim that residents have been officially free of rats for more than seven decades, while also indicating minor breaches.
On confidence: Two primary sources from a reputable news outlet directly state that Alberta has claimed rat‑free status since the 1950 Rat Control Program, covering more than seven decades.
Important context
The claim refers to the official status, not the absolute absence of any rats. The province acknowledges occasional sightings but maintains that there is no resident population.
