Is material usury in Canada prohibited by law?
Having a European background, I know that material usury in Europe is prohibited if the price is more than two times the average price, and there is a critical situation or some kind of abuse (like overcharging foreigners). While having to pay hundreds of Euros to get a replacement for a lost apartment key (critical) would apply to this criterion, getting a cheap collectors edition of something of course not (not critical).
I was wondering whether the same applies to Canada, yet I was only able to find usury prohibition laws in connection with interest rates.
