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.

this number called me yesterday and today... so annoying !

i am about to call revenue services and get them to cease and desist collections actions against me because according to my calculation based of revenue canada income tax returns since 2008 b.c. govt owes me for overbilling on my msp

It's simply a scam.

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

I did *67 on my phone and dialed this (250) 999-1108 number back. It went automated and said it is ARC Accounts Recovery Department so it sounds like it is a collection agency.

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.
