There are so many options for sending it, the price would be different depending on what you want. Your best option is to go to CanadaPost.ca (this is who I sent it with) and go to rates and prices, then click on find a rate, type in your info and such and it'll show you all of the options you'll have when you go to the post office. I highly suggest doing this, it saves the time you would spend asking the post office employee a million questions while a line forms behind you haha I believe it ended up costing us about 53 dollars, but like I said there are tons of options that are cheaper, we just went with the fastest one because we wanted that thing GONE haha
Of course if you don't want to use Canada Post you can still do the same thing with UPS or FedEx or whatever you plan to use, they all should have something silimar on their website to help you calculate the cost. Good luck friend! =)
