I believe in Canada there is no such rule against Day Traders. I just called and asked the rep. for my Ameritrade Canada and he could not comment on such rule. Did I miss something? Were you refering to Canadians?
Actually its the NASD that passed the margin rule requiring 25k for anyone that fits the SEC's definition of a pattern daytrader. This means geographical location is unimportant. So yes you can be a daytrader but your broker will be obligated to restrict your account to cash only (no margin) assuming you don't meet the 25k requirment.
