Pets/service dogs on provincial buses

In January of this year it seems ANT issued the “Regulation of Mobilization of Assistance and Company Animals Within Intra and Interprovincial Public Ground Transport,” establishing the technical standards for their transfer.”

Has anyone had experience with their pets or service animals on buses this year? If so, what documentation did you have to provide, etc. I’m particularly curious if you have a medical service animal and what type of certification you provided.

Thanks in advance.
