Plaid is expanding its financial services platform to Canada, enabling innovation and providing access to the country's largest financial institutions. The launch extends Plaid's API suite to include EFT authentication via Auth endpoint, covering major banks such as Royal Bank of Canada and Scotiabank. Existing customers can now access Canadian institutions by including 'CA' in their countryCodes array during Link initialization, while new customers can sign up for a Plaid account to utilize the platform's services. The expansion aims to support cross-border institutions and facilitate product development specific to Canada or expansion across borders.
