This number is a scam - i KNOW for a fact i do not owe anything. First of all - i keep very very tight hold of my credit, have gotten a refund from the government every year, my work covers my mspo plus I called them and they said my account was clear. i have one credit card that has no balance, i have students loans in repayment.
this is a scam and i feel bad for anyone they are harassing that has debt and falls for whatever scam this is. Everytime they pretend I owe somethign and I tell them no i do not i talked to CRA last time you called from a different number - it stops for awhile, then it continues form a different number in a few weeks.

constant calliing and never leaves mesage

I've been getting a lot of call from this number too. They left me message saying we're owing some debts from msp and they're taking over the debt amount. It's recovery account company but it's stupid becuz we don't owe government any money. Be aware guys!

They are collection company that buys debts from the goverment. THEY ARE NOT PART OF THE GOVERMENT!! Any collection agency is only allowed by law to contact you once a month, any more then that is harassment! The debt is allso only good for 7 years from the time they bought itfrom whomever sold them the debt in court. Basiclly these debts get bid on in a sort of auction through court. After 7 years by law they can not collect anything thanks to the statute of limitations law. FYI and pass it on.

They're calling me too.  I have never made enough money to owe the government anything.  Wtf

They call a lot from different numbers. But never say who they are calling for or what they are calling about. It's never a real person either.If it is the government then why don't they just leave a message? If I owe money to the government then I want to talk to them about it. But using some automated system that doesn't say who it is for or why they are calling won't get them a lot of returned calls. It could be a scam.

Phone numbers get recycled all the time.They recycle phone numbers after 3 months, so many people could have had your phone number before.Don't worry about it.
