Why can I no longer use a bunch of Google services?

It works for me if O logout of Gmail hosted Telus email.

I tested this by logging into Telus webmail and tried to access Google Maps. I received the error you mentioned. When I signed out I was then able to access the service.

I believe Telus only has access to email as opposed to the full Google Workspace (formerly G Suite) package.

NormO  Google shut maps down Probably want money for it.  There is another  called ( instant google street ) No map shows your house. Go look at it they want 7$ a month for pro version. Polecat
