says I owe the gov't money in the amt of 10,000. Threatened with jail

(613) 7xx? The Kingston area of Ontario. Only $10,000 Canadian Peso's? I wouldn't sweat it. What's that? 50 bucks U.S.? Ask them if they'll take Canadian Tire money. By the way. Your call? It's a scam. A well known one. If you really owed money you'd of gotten something in the mail. Not fax, text, email, or phone call. Remember: Debt is Civil, not Criminal. There is no debtors prison in Canada or the USA.

Scam ... Scam ... Scam ... Scam ... Scam
The CRA does not make this type of call, ever.

Scam...   tried to tell me that i owed the gov'n $10000 and am liable for all legal actions.

Like everyone else here is saying, CRA does not make calls like this.

Just ignore the call.

These guys called me again. I checked the number out and called them back. When he said it was the CRA I said, no your not so who are you ? He told me to go away and do not F$#@^& call back
