National Bank of Canada (Banque Nationale du Canada, TSX: NA) is a Schedule I chartered bank headquartered in Montreal, Quebec, founded in 1859. It is the sixth-largest of Canada's Big Six banks and the leading bank in Quebec, serving personal, commercial, wealth-management, and financial-markets clients. On open finance, National Bank is a notable first-mover: it was the first major Canadian bank to launch a secure, consent-based data-sharing API for retail customers, but it does NOT operate a public self-serve first-party developer portal. Programmatic access to customer financial data is delivered through aggregators rather than a downloadable public API — principally Flinks, the Montreal aggregator in which National Bank holds an ~80% stake, via its Open Banking Environment (OBE), and also through Plaid. National Bank and Flinks are founding participants of the FDX Canada working group, aligning their data-sharing on the FDX technical standard, and the bank is positioning ahead of Canada's forthcoming, legislated-but-not-yet-operational Consumer-Driven Banking framework (Budget 2024 / FCAC oversight). Today access is voluntary and aggregator-mediated; there is no operational open-banking mandate and no public first-party API surface.
