They mention Canada and other destinations outside the United States such as Burmuda and the Bahamas in several of their press releases. I think Mexico was also mention in a handful. Mostly in the press releases and news articles regarding the EMB 190s. This doesn't mean that they will fly to Canada, jetBlue list alot of potential routes out of LGB, BOS, and JFK and most of them still never happened before, its just a matter of time, I'm sure their considering canada cause if their not, theres really no point in mentioning it in some of their press releases.
