The Metropolitan Transit Agency is the one making the acquisition, not the city or the province. It's a non-provincial agency which is managed independently.
You are setting limits. So, I would like our definition to be taken into account. Indeed, when we say “transit agencies or similar bodies”, that includes all public transit services managed by governments, municipalities or groups of municipalities. In some cases, they go beyond the boundaries of census metropolitan areas. Once you go beyond the boundaries of a CMA, your definition no longer applies.
I don't want this to be restrictive, because systems are now being developed that sometimes go beyond the boundaries of census metropolitan areas.
