Scams are a constant. I got a call last year from someone purported to be from CRA. I didn't answer but the message left warned me that I was in legal trouble and I had better call back soon, and that I could be prosecuted and was under surveillance. All bullshit, of course. Even if I hadn't worked for CRA and didn't know what they do and do not do I'd have recognized that.
Lately what I get are 'urgent' texts warning me that my bank account is in trouble. I've gotten these from BMO, Scotia, and RBC. They all have some variation of a warning that my account has been 'restricted' or 'compromised' or that there's been some sort of suspicious activity. And would I kindly click on the link and take care of the issue. Got one from Bell telling me they had mistakenly overcharged me and all I had to do was click on the link to get my funds back. They often have small, but telling spelling mistakes, indicating they're likely coming from non-English speakers. It's now a ubiquitous part of our electronic life.
The sad part is the people most likely to fall for these things are the people who can least afford to lose the money it will cost them.
