Expanded Canadian coverage and country filtering in Link

The text discusses recent enhancements made by LinkPaolo Bernasconi & Jesse Dhillon to their Canadian coverage, including the addition of support for several new institutions such as Desjardins, National Bank of Canada, President's Choice, and Simplii. Furthermore, users can now link accounts from many credit unions in Canada like Vancity, Coast Capital Savings, Conexus Credit Union, etc. Alongside this expansion, a country filter has been introduced to make it easier for Canadian users to find their banks. Developers can specify whether they want to show only Canadian or US institutions, or both. This feature aims to provide a more seamless experience for Canadian users and potentially increase conversions in Link for an app or digital service. The 'countryCodes' parameter in the API docs provides more information on how to use this country filter.
