Counterpoint. I use Interac e-Transfer all the time. Zero problems. No spam. No fraud. Works fast. There is auto-deposit now so it's even more frictionless than before and it's sped up to essentially instant on regular purchases. And yes, I pay my rent with e-Transfer.
Agreed and it's free across all banks, and some have even raised daily transfer limits to $7000 or more. It's also one of the easiest and fastest no-fee methods to transfer money into crypto exchanges/platforms in Canada.
