How many dentists are there in the Peel Region

That is like asking how many dentists in the Greater Toronto Area. Why would you want to know. Get a phone book and count them. Phone the dental registry and ask them.

This is a world wide site. There could be countless 'Peel Regions' in the world. I for one have never heard of it. GTA, tick?

The Greater Toronto Area, including Peel Region, Brampton, Mississauga and Scarborough have over 6 million people residing.

The Greater Toronto Area is only two hours west of where I live.

Peel Region is common terminology for me and I doubt there are many 'Peel Regions" in the world.
