Hi @kflint1,
If you see that message, your school/institution is still using what's considered to be an older integration with Google that will soon be removed from Canvas. The good news is that there is a newer Google integration that your school/institution can upgrade to (but I think you will need to re-embed things after the upgrade if I understand things correctly). Hopefully your local Canvas team there already has a plan for this upgrade, but it wouldn't hurt for you to reach out and ask them. The Canvas team is usually located in the eLearning, IT, or Digital Education areas.
I hope this info helps!
