I don't know enough about this area to be able to tell you that. I can perhaps tell you an anecdote that might amuse you or horrify you.
I was recently involved in a case involving the Charter of Rights, in which a woman had to take time out of paid employment to care for a disabled family member and was claiming that she should have a caregiving dropout from the CPP. Her claim was rejected by the appeals tribunal on the grounds that if they gave her a dropout, then people who volunteered for the boy scouts would also want one. The tribunal was apparently unable to distinguish between caring for a dependent human being and volunteering for the boy scouts, and the lawyers from the Department of Justice took the same approach.
