What are validation rules for Canadian Health Care card numbers in every province?

Question

I know that in BC first digit is 9, and length is 10 digit... I wonder if other provinces have similar rules. Besides BC uses MOD11 check digit routine to validate card number. Do other provinces have similar standards?

Answer 1

The first digit on my OHIP (Ontario Health Insurance Plan) card also starts with  9 and is followed by seven more digits and a W.

It's an older card and, until I'm forced to do so, I refuse to get (and pay for) the newer photo ID card.
