The Canadian Charity Casinos have little to do with charity.
Typically, they permit BJ bets of only $10 to $100.
With marginal penetration, there are no meaningful profits to be had.

This must not be confused with "Charity Nights" in the USA where non-
profit organizations are sometimes permitted to deal BJ where the
house wins all ties. No Pushes. You cannot overcome that thievery !
