Due to Canadian law the cost of airsoft is much higher in our country thank it would be in places like Japan or the USA. A budget of $50-$250 does not really open a whole lot of doors. As stated above if you can expand your budget to at least $300 or more then its possible that you might be able to find something of fair quality from a Canadian retailer.
Since you did not state a specific make or model I would like to ask you if there is a specific type of gun you like? Lets start there.
