Literally can’t think of a single conspiracy theory about why Canada specifically brought people from that region. Seriously unhinged to bring up anti-semitism.
What region ? What are you talking about ? Nobody is bringing anyone from any region. Human beings migrate for better opportunities, and over time groups find their niches and areas of expertise. That manifests as a concentration geographically or professionally as it's a reinforcing loop. That's why group X is dominant in trade Y in city Z.
