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.

It's simply a scam.

they been calling my house everyday in the mornings then in the afternoons never left a message then i answered the phone and said stop calling here and hung up then 2 days later they call again and left a message for my boyfriend stating who they are why there calling saying he owe canada revenew and there trying to collect to call them back funny is thing he dont owe the gov anything

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.

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!

ARC collects past due accounts for msp and other government related debts, they call me constantly from many differant ph#'s and area codes.. All automated and I don't answer to robots! When I see an unknown # on my phone, I google it first, and then I know who it is next time.
