In my experience, I have found that the international opportunities available to me have been greatly enhanced by having a Bachelors degree. None of the international moves I have made would have been possible without it.
You will want to check the requirements for applying for a work permit for Canada to see whether a Bachelors degree is required for your field of work. (Since there are already many Canadian Java software developers, you may need to show that you bring exceptional skills to your employer.)
