We need to question Statistics Canada's definition of "protestant"

The Toronto Star offers this chart of how many people from various religions marry outside their faith. It is sourced to Statistics Canada.

"Protestant" is divided into "Mainline", "Conservative" and "Other". The footnote defines "Other" as:

Includes New Age, Aboriginal Spirituality, Pagan, Scientology, Satanist, Wicca, Gnostic, Rastafarian, Unity, New Thought, Pantheist and other small religious groups.

This is a serious problem. The definition of Protestant clearly identifies it as a form of christianity. I don't know about all these religions, but Pagan, Scientology, Stanaist and Wicca are definitely not christian religions!

Does Statscan always include these other religions in with protestant? If so, that's a huge problem!
