How do you search by name for marriage licences in Canada

I don't understand your question.

Are you asking how to go about getting a marriage license, or are you asking how to check if someone else got a license?

I would like to check if some one else got a licence.

Unlikely that you'll get that information.

You could always call the person and ask. :)

The entire country? Do you have even an idea of which province? Which town? The date? His name? Her name?

Why do you want to know?
