Might I need a credit score to rent, or for any other non-borrowing finances?
Credit scores are not such a big deal in Canada as they are in the US and even some European countries.  One reason for this: the Social Insurance Number (SIN number) isn't used for so many purposes like the Social Security Number (SSN) in the US.  The SIN number isn't even required to get credit (but with some exceptions it is needed to open an interest-bearing savings account, so that the interest income can be reported).  You can refuse to provide the SIN number to most private companies. Canada also has one of the highest per-capita immigration rates of any large country, so new arrivals are expected, and services are geared up for them.  Most of the banks offer special deals for "New Canadians".  You should get a credit card (even if just a secured credit card) through them with one of these offers to start a credit file anyway, but there's no need to actually use it much.  Auto-paying a utility bill through the card, and paying it off in full each month, is one way to keep it active.  No need to ever pay any interest. Most major apartment rental firms will expect a good proportion of their renters to be new to Canada, so should have procedures in place to deal with it (such as a higher deposit).  You should not give them your SIN for a credit check, even when you're more established. Same for utilities, they can just charge a higher deposit if they can't credit check you.  For private landlords, everything is negotiable (but see the laws link at the end of this answer). You will later need a credit rating for a mortgage on a house (if not paying cash), so it's worth getting that one token credit card.  Useful for car rental also. Here's a fairly complete summary of the laws on renting in Canada, which includes the maximum deposits that can be asked for, and notice periods.
