Receiving is the easy part
At launch, institutions only have to receive RTR payments. The hard part is sending: fraud controls for irrevocable payments, liquidity and pre-funding, and 24/7 operations. Plan that work now, not in 2027.
Receive-only is a temporary posture
Canada's Real-Time Rail is scheduled to launch with a receive-capable bar for participating institutions. Sending is optional at first. That framing is useful for a controlled industry start. It is not a strategy.
Receive-only keeps the political heat down and lets scheme operators prove clearing and settlement under live traffic. For a bank, credit union or PSP, it also creates a false sense that the hard engineering is done. It isn't. The irreversible payment, the liquidity model and the fraud stack all sit on the send path.
What sending actually changes
An irrevocable credit means your fraud and dispute processes cannot rely on a chargeback culture. You need pre-authorization logic, velocity controls, beneficiary risk signals and an operating model that can freeze a pattern in minutes, not days.
Liquidity is the second shift. Pre-funding through Lynx, intraday monitoring and what happens when a large corporate client spikes send volume are board questions, not only treasury questions. If you treat them as a 2027 project, you will discover them under a deadline.
The third shift is hours. Real-time rails do not respect your branch window. Contact centre scripts, exception queues and vendor SLAs have to be honest about nights and weekends.
Interac, hubs and the core
RTR does not land in a vacuum. Most Canadian institutions already run Interac e-Transfer, a payment hub and a core that was never designed for continuous irrevocable credits. The useful work in the next year is a gap map from receive-only to full participation: which platforms move, which stay, and which vendor promises collapse under send volume.
I have spent years inside that map at BMO—across Payments Canada connectivity, Interac, hubs, core, fraud, liquidity and operations. The institutions that look calm at full participation are the ones that treated receive-only as phase zero, not as the finish line.
What to do before 2027
Run a fixed-scope sprint that forces the send path into the open: fraud and irrevocability controls, liquidity and pre-funding through Lynx, Interac and hub impacts, and a cost envelope the CFO will recognize. Bring that to the board while receive-only traffic is still light.
If the answer is that you will stay receive-only longer than peers, say so deliberately. Do not arrive there by accident.
