Alternate theory

Dozens of Winnipeg women, desperate enough to sleep with ugly Winnipeg men, try to save face by claiming they were given a roofie.

No I'm serious: having been to Winnipeg a few times (I was, pre-COVID, supposed to be there this summer actually) and talking with Winnipeg girls who have, not meaning to stroke my own ego, thrown themselves at me because of hot I was by virtue of clearly not being a local, this theory is easily more common than the CBC "oh woe is woman" talking point.
