Canada's Open Banking Push Presents Both Threat and Opportunity for Major Banks
As Canada advances its open-banking framework, analysts say the move could gradually chip away at the Big Six’s market share while also giving them new data-driven growth options.
Canada’s gradual implementation of open banking, sparked by 2024 budget legislation, aims to let consumers and businesses share financial data securely across institutions. The Department of Finance projects a $457.7 million implementation cost and $13.2 billion in benefits over a decade, while noting that about nine million Canadians now rely on insecure screen-scraping. Analysts such as Mark Schofield and John Aiken argue that the Big Six banks may see a slow decline in market share but can leverage new insights into customers’ holdings at rival firms to boost in-house services.
Scholars like Henry Kim suggest the banks’ oligopolistic position could enable them to acquire or replicate successful fintechs. At the 2026 Global Open Finance Summit, Steve Boms indicated that consumer-facing tools could be available toward the end of 2027, and the Canadian Bankers Association pledged to support responsible innovation. Overall, the shift is expected to reshape competition while offering Canadians a unified view of their finances.
