RTR's membership requirements are set by PayCan, who have a mandate to foster competition. Any FinTech who can meet requirements can, in theory, hold a settlement account on RTR and participate. Interac has an incentive to keep the club small, so to speak, and prevent new up-and-comers from cannibalizing their market share.
From a competition lens, the hope here is that RTR levels the playing field for both the big banks and fintechs and opens the door to a lot more consumer-facing innovation. That will, of course, depend on the network effect and who gets onboard.
