Hi there,
All of the test pilots that I know of in Canada (which is by no means exhaustive...) have graduated from one of the recognised test pilot programs - USAF, USN, Empire, EPNER, or NTPS. Anyone who hasn't is armed with thousands of hours of flight experience on a type relevant to their current job. I have worked with several flight test engineers who progressed from entry level positions into their current jobs through years of engineering experience, plus a good number of flying hours and supplementary courses. So...PPL plus an entry level job is where you need to start if you don't want to go the military route; however, there are a good many reasons to take that route, as it shortens the road by decades...
The Air Force wouldn't accept you as a pilot with glasses (your vision can degrade somewhat once you're trained, but you need a fairly high standard to begin with) but you could go as an Aerospace Engineer and be eligible to apply for a Flight Test Engineer position once you have three years experience in your trade (FTEs are typically taken much younger that QTPs). If accepted, you get the million dollar course and owe the military five years before you can move on. The Air Force Trains between 2 and 4 FTEs a year, and it is these people with whom you'll compete in the limited Canadian job market.
As for Electrical Engineering - nothing wrong with it! Any of the test pilot schools are looking for an honours science or engineering degree (with the possible exception of Empire - no degree required, however IMHO the RAF gives its pilots a background in aeronautical science that is second to none, so don't let a piece of paper that says B.Sc. fool you...). More and more work in industry is centred around systems testing and development, to which E.Eng. is quite applicable.
PM if you'd like to chat further.
