Honestly, I do not know anything about Canadian law, but I doubt that getting pregnant gives anyone "the right to be married" anywhere.
If Canadian law is anything like U.S. law, minors do not have "the right" to anything until they turn 18 years old.
As far as I know, marriage is universally accepted. Meaning that if you got legally married in one country, you are legally married in every country. Provided that the person who performed the ceremony had the legal right to perform ceremonies in that country.
A little advice, if you are pregnant, don't get married based soley on that fact. It does not make a difference to the baby if his parents are married or not, they are still mommy and daddy.
