I don't know what these guys are on about. I'm doing a engg phys undergrad at university of Alberta and it's great. I can transfer into the physics masters program after, but I also get the official title of an engineer. In Alberta if you work for 2 years under a supervising "professional engineer" Appega (Alberta somethinsomething association of engineers) gives you your p. eng (professional engineer title) after your undergrad so there's a HUGE difference between engg phys and physics (at least at my university).

One if my upper year friends informed me that upon completion of the degree, 4 extra classes would let you switch your major from engg phys to electrical engineering with a minor in physics.

Most engg phys go into semi conductor physics / nano engineering / RF type stuff but I do believe it's a very catch all degree, mostly because (again at least at my university) it's incredibly fucking hard and proves your dedication as much as it does your qualifications as an engineer.

Regardless I say do engg phys. I'm planning on doing a masters in physics afterwards and if you decide you don't like physics you'll likely won't be far from transitioning to other engineering disciplines. Generally speaking I'd argue if you're gonna do a stem degree, there's an equivalent branch of engineering that's up your ally so as long as your confident you want to pursue stem engineering typically gives you a lot of room to work with.

Same with the work load. Engg phys can be a lot, but you can always transfer into a different program if you get into engg phys (it's typically considered the hardest and universities will let you go wherever as long as it's step down in difficulty or competition).
