There was no US DVD release, so you'll have to import it or find a store that imports games. GoGamer.com used to carry it, but the site is down (they used to have a messages saying they were reorganizing and would be back 'soon', but now it is just a logo). AFAIK nobody in Canada that carries the game (Amazon/Gamestop) ships outside of Canada.
A few people in the UK mentioned ordering from Play-asia.com (though it doesn't look like they still have it in stock), or you should be able to order from another European country (except Germany), since they include the English language version of the game (but not necessarily an English manual).
I can't buy a hard copy?
