Can you integrate Moneris + Interac e-Transfer + Bambora + Stripe Canada?

Yes, this is the standard Toronto payment stack and we've integrated all four on Magento 2.4.x. Moneris (Toronto-HQ, RBC + BMO joint-venture) is Canada's largest payment processor, mandatory if your acquiring bank is RBC or BMO, and strongly preferred by Big-Five-Bank merchant accounts. We use the Moneris Hosted Tokenisation + Direct Post APIs. Interac e-Transfer is the Canadian-only bank-to-bank rail, ubiquitous for B2B Net-30 and low-AOV consumer payments, we wire it via the Interac for Business API. Bambora (now Worldline-owned, Toronto office presence) is preferred by some legacy Canadian merchants, we maintain or migrate as needed. Stripe Canada (Toronto office) is our default for DTC + subscription + multi-currency. We typically wire Moneris + Stripe Canada as primary, Interac for B2B, plus Klarna Canada + Sezzle + Affirm for BNPL.
