There are only three groups of people who can legally solemnize a wedding ceremony in Ontario:

1. Religious Officials;

2. Ontario Municipal Clerks Designates; and 

3. Judges/Justice of the Peace. 

Ontario maintains an electronic list of registered religious marriage Officiants authorized to perform marriages in the province. I am a metaphysical minister and for legal confirmation, you can find my name listed there under the town of Waterford!
