If you’re in Toronto or have a Toronto number they target Mandarin since it’s incredibly prevalent in the city. Those are also the only 2 languages I receive as well.

I’m also Canadian and I do get random calls in Mandarin sometimes. I didn’t know what they saying so I just hung up, but I guess it’s likely they were scam calls along these lines.

HTTPS means nothing. All sites are HTTPS these days. If your only check for a scam is that then you’re fucked
