description: BMO Financial Group (Bank of Montreal) is one of Canada's Big Six banks and a Schedule I domestic chartered bank,
  founded in Montreal in 1817 as Canada's oldest bank. It is a diversified North American financial-services provider serving
  personal, commercial, wealth, and capital-markets clients across Canada and the United States (where it operates as the
  separately chartered BMO Bank N.A.). BMO runs a first-party, bilingual (EN/FR) commercial developer portal at developer.bmo.com
  for Online Banking for Business customers, publishing OAuth 2.0-secured Account Information, Account Validation, Image Retrieval,
  Payment (domestic and international / embedded finance), Authorize, and Encryption APIs on an IBM API Connect platform with
  a free sandbox and pre-production environment. Documentation and OpenAPI/API Explorer specs sit behind an approved organization
  account, so the surface is partner-gated rather than openly downloadable. Canada has no operational open-banking mandate
  yet — the federal Consumer-Driven Banking framework (Budget 2024 / Fall Economic Statement 2024, overseen by the FCAC) is
  legislated but not live — so consumer data access today remains voluntary and largely aggregator-based (Flinks, Plaid),
  while BMO's own public program is a commercial treasury/ payments API offering.
