It's a recording stating that it's a call from Canada Revenue Services and that there will be legal action taken if we don't return the call.

my mother got this call and said they are from CRA saying that legal action will be taken for owing the government money $500,000 and that she can pay them early for a discount for $100,000 before she gets arrested today and the wont come after that. this exactly why we cant trust people or have nice things luckily i was home to calm her down and tell her what to do. dont give them information or do anything they say just hang up and report the number

They called stating they are CRA. They are not.

I've had that call two mornings in a row....very early!

Recorded message telling us that it was from CRA and that it was imperative that we return a call to this number immediately regarding a pressing issue before legal action was taken.  We hung up.
