One of the biggest differences between one- and two-year MBA programs is that the latter allow you to gain much more hands-on experience, through exchanges, internships, etc. This is especially important for those (like you) who want to transition into different industries or functional roles.
The McGill program, for example, offers an internship, and opportunities for international exchanges and study trips.
If you did this you could do an internship in one of MTL's start-ups - and use the second year to hone a business plan. McGill does tend to feed the local start-up scene, perhaps even moreso than HEC.
