There's currently a full-size Arrow replica on display in Toronto, at the Canadian Air and Space Museum. I haven't gotten a chance to go there yet, but the Canada Aviation and Space Museum in Ottawa currently has an original nose section on display, which I believe is the largest surviving piece. I can attest to the later being a very good aviation museum all around; I recommend it to anybody who's interested in that sort of thing. The nearby Diefenbunker museum is also very cool if you're interested in cold war stuff.
