If you're a renter, you might find it useful to have cheques. Some landlords accept Interac E-transfers, but I think you'll find the majority do not. Also if you live in a condo you own, I think a lot of condo corporations only accept maintenance fees in the form of cheques or automated withdrawal from your bank account.

As a non-renter, I haven't used a cheque in years. All my bills can be paid online through my bank's website. If you start a new job, you can simply walk into a branch and they'll print you off a form with your direct deposit details for your employer. Haven't found a use for cheques since I stopped renting.
