Ran a check pass on this one, because the details are the good part. Three flags:
1. The mayor who thought the program was "a distraction cooked up by the ruling United Conservative Party." The UCP was founded in July 2017. In 1950-51 the government was Social Credit; Manning was premier from 1943 to 1968. Suggested fix: "the ruling Social Credit government."
2. "the state's eastern border" — Alberta is a province, not a state. Should read "the province's."
3. The section heading reads "Eratication."
What held in the same pass: the zone arithmetic (600 x 29 km = 17,400 km2, which matches the figure given a few paragraphs later) and the warfarin-from-Wisconsin origin.
Border quarantine at biological scale is such a rare success story. Maintaining a zero tolerance perimeter takes decades of boring, disciplined institutional execution. We touch on systems design and deterministic rules in our English section: https://gzambrano.substack.com/s/english
That line traces to one source, and it's older than the post: Michael J. Dorrance's 1984 account "Rat Control in Alberta" (Proceedings of the 11th Vertebrate Pest Conference; PDF free via UNL DigitalCommons, vpc11/15). It's the only place I could find the detail, and the post's phrasing follows it closely. Quoting the paper: "Indian reservations and Metis colonies in north-central Alberta presented a special problem in public relations. Natives did not want to have rats but were only familiar with strychnine, and assumed that all poisons had the same properties. Warfarin baits were removed or destroyed by Natives because they feared for their children, pets, and livestock." The warfarin-chewing pest-control officer is on the same page.
For further reading: Alberta.ca's "History of rat control in Alberta" is the program's own record (1951 pamphlet, the posters, the arsenic tonnage); Frances Reilly's NiCHE essay "Rats and Communism" (2016) is the Cold War-framing source the piece links. The 1950s posters and pamphlets themselves are in the Provincial Archives of Alberta.
One note: the 1984 source uses "Natives"; modern writing would say First Nations and Metis.
Great piece, but the government of the day was the "Social Credit Party," not the "United Conservative Party" (which is party of government today).
Technically they were “SoCred in name only,” the original Douglasites having been usurped by pro-bankster successors by then
This seems very un Canadian. Have any of the rats tried claiming that they need asylum?
Alberta’s self-image as world’s only rat-free region shattered by discovery of rat

really enjoyed this article but found it hilarious that this came out but 10 days later

"Indigenous Canadians in particular were not fans of rats" - interested to know more about this, would any sources or further reading be available?

In BC and the larger Canadian cities, rats are walking around in broad daylight.
The banning of certain older poisons to avoid poisoning wildlife is making it harder to reduce the rat and mice population.
Love to see a practical solution to reduce the number of these perennial pests.
