TL;DR: this is not Brazilian Pix or Indian UPI.

Meh, just another "payment option".

These payment systems need network effects, otherwise they just won't matter. Another private provider won't generate these effects. Just look at the list of participants, they're small players in Canada's marketplace. They won't generate net effects.

Besides, in times of renewed imperialism it is very crucial that a country has full control of their payment systems.

And, at last, they must offer guarantees that there will be no friction and won't be subject to enshitification.

So, what Canada needs is a system implemented, enforced and managed by the government, like Brazil's Pix and India's UPI.
