Earlier quoted context omitted.
No, it's true in the UK. I had this issue, and had to get a credit card and buy stuff on it for a year... basically without using credit you may not have a credit rating. I always lose my cards and have to get them replaced, so have been back on just a debit card for a few years now.
Can second this. I had to get a credit card as mortgage got denied because my credit record didn't exist. Three months after the card, I got approved. This is despite me earning an extravagant wage relative to my age for over a decade and never missing rent/utilities/council tax. Bad system.
It isn't that a lack of credit card hurts your credit rating, but that a lack of any credit hurts your credit rating in Canada or the US.
There are other ways to get an initial credit rating than a credit card, although I agree that this is the path most easy, and chosen by many to get that first rating.
The method I employed, was to buy a car and had a parent cosign. I made all the payments, and this was enough to kick start, and give me at good credit rating.
