Cognito in ca-west-1

Hello.

As of March 2024, Cognito support has not been announced for "ca-west-1".
There is also no announcement as to when it will be supported.
https://docs.aws.amazon.com/general/latest/gr/cognito_identity.html

Once it becomes supported, it will be published on the AWS update information page, so I recommend checking it out.
