I received the same phone two days in a row.  Apparently I'm going to be arrested some time today.

An female Indian accent voice left at my phone. Phone ID is IRS. She said she is going to file law sue against my SSN.

There is a widespread IRS (or CRA) or "tax scam" being  practiced by scammers on both USA and Canadian residents.

USA tax payers should read this:

Canadian tax payers should read this:

Short answer:
The IRS never initiates a contact via phone.
They always send a snailmail first.
