The Nismo has been available in Canada since last year actually. I'm not a big fan on the looks though. The miniscule performance difference, mostly from a slightly altered factory tune, has not produced a measurable performance difference, based on third party reviews. Nothing you can't match or exceed with basic bolt on mods and/or Uprev tune. Plus for the cost and the lack of nav and leather...I personally don't think it's worth it.
I would still get a Sport model with Navigation Pkg, which will give you the sport brakes (just like the Nismo), nav and leather. Go to Sherwood Nissan and speak to Kris Suchy (Sales Mgr). They'll set you up with whichever model you want. Happy shopping!
