If the message they leave says to call +1 866-303-3503 it's a legit phone number for the NSLC.

Surpisingly, it was a courtesy call to see if I qualified for and had applied for interest relief as my loan will go into repayment soon.

This isn't a scam, its a contracted service for the NSLSC (National Student Loans Services Centre). They call to remind you when your loans are about to enter re-payment, are in arrears or have other issues. It's not a "bad" call necessarily, unless you're actually behind on payments.

The number is legit and it is from the NSLSC. Someone from this number called me tonight just before 9pm and when I answered, he/she hung up. I called the number back and the guy on the phone said he was calling on behalf of NSLSC and asked for my SIN. I told him that I googled the number and thought it a scam. I said I was going to call NSLSC directly. He offered the number but I refused stating that I had it. I then called the NSLSC directly and after punching in my SIN, was re-directed to the number that initially called and actually got the same guy! I told him that I was following up on a suspicious number and that I spoke with someone earlier and he said "that was me". They seem totally legit. But be suspicious BECAUSE YOU NEVER KNOW...IT ONLY TAKES ONLY PHONE CALL! Stay vigilant!

They are calling you because you owe money on your Canada Student Loan.In fact it's because you are behind in payments.And if you don't answer, and deal with their s**t, they will hand over your account to a collections agency, and damn your credit rating to hell.
