Definitely check with an attorney, but according to

Becoming certified to perform marriages:
The regulations in Ontario are believed to be typical of provinces across Canada. Marriages in the province can only be performed by:
Members of the clergy who have a certificate of registration from the Office of the Registrar General for the Province of Ontario.
Judges.
Justices of the Peace.
Clergypersons set their own fees for performing marriages. Civil marriages by Judges and Justices of the Peace cost $75.00 (as of 2001-MAR). In addition, there is the cost of the license which is $75.00 plus an optional fee by the municipality.
In order for a religious leader (minister, pastor, priest, priestess, rabbi, imam, etc.) to perform marriages in Ontario, she or he must:
File an application form with the government.
Include a document proving that they have been ordained or appointed as a clergyperson.
Include a letter from their faith group authorizing them to solemnize marriages.
Include a statement that discusses the name and location of their "church," the numbers of its members, the congregation's growth rate, etc. 1
However, the faith group itself must first be be registered by the Office of the Registrar General. That office requires detailed information from any faith group seeking registration. This includes:
How clergy are appointed and dismissed.
A copy of the marriage ceremony.
A copy of the group's form of worship "namely actions or practices of displaying reverence or veneration paid to a being or power regarded as supernatural or divine displayed by appropriate acts, rites and ceremonies."
A letter stating who in the group will keep track of clergy registrations.
A copy of the group's incorporation papers.
A copy of the group's registration as a charity by Canada Customs and Revenue Agency.
A description of the organizational structure of the group.
Signatures of at least 25 group members, not including clergy and their families. 1
This Memorandum is obviously based on a fairly rigid, Christian model of what a religious group should be.
It refers to a "church," rather than a generic term, like "meeting place."
It assumes that the group owns or rents a building. That might make it difficult for Aboriginal, Wiccan and other Neopagan groups to register. Some don't always meet in a building, preferring to assemble in a forest or other area away from asphalt and close to nature.
Some groups may not have a standard marriage ceremony. Some Unitarian Universalist groups, for example, expect the future spouses to write their own ritual and vows.
The memorandum appears to assume that each faith group is a denomination of some larger religion. A small new religious movement may not have denominations or individual congregations.
It seems to imply that only theistic religious groups can be registered. If rigidly applied, this would eliminate entire religions from consideration. Buddhists do not generally worship or recognize a deity. Unitarian Universalist congregations do not generally worship a deity. Members of the Church of Satan are generally Agnostics.
The office appears to be quite concerned that a "denomination" prove its existence over a period of time in the province and elsewhere. We have heard a rumor that a group must have been established in excess of 15 years before it can become registered. This would discriminate against new religious groups, regardless of their sincerity or stability. We suspect that a constitutional lawyer would have a field-day with regulations such as these.
