I wish that this claim was actually just satire, or better yet, wasn't said in the first place, but it is as a matter of fact, false. A BBC article described it as "a baseless claim", and that city officials told them that there have been “no credible reports"
additionally, in the BBC article they explain how it gained so much traction initially, which was caused by it being "spread on social media, with Republican vice-presidential candidate JD Vance promoting it on X. The post has had more than 11 million views."
CBC also has an article that has the same stance, as well KTVU, USA Today, & NBC News, to name a few.
