From ANIMAL PEOPLE, March 2011:

OTTAWA–The Canada Revenue Agency on February 5, 2011
published new regulations governing animal charities which would
revoke the nonprofit status of any who oppose vivisection, hunting,
trapping, the fur trade, seal-clubbing, animal agriculture, and
any other legal use of animals.
“Under common law, an activity or purpose is only charitable
when it provides a benefit to humans,” the Canada Revenue Agency
regulations assert. “As far back as the 19th century, the courts
have stated that promoting the welfare of animals ‘has for its
object, not merely the protection of the animals themselves, but the
advancement of morals and education among [people].’ To be
charitable, the benefit to humans must always take precedence over
any benefit to animals. If a purpose or activity that promotes the
welfare of animals harms humans, or has a real potential to cause
significant harm to humans, it is likely not charitable.”
