I'm currently in Honours Biology (Physiology Specialization):
- If you're interested in human biology, this is definitely the way to go. We focus a lot on cell physiology, the cardiovascular system, and respiratory system as well as other systems with less emphasis. There are a lot of psychology, genetics kinesiology, and ecology/environmental science based courses on the physiology course list - so if you wanted to minor, it would be quite easy to do so. I'm currently doing a minor in psych and many of my physiology courses count as psych credits.
There's a third year course that discusses advanced topics in physiology, where there are student and guest presenters from various universities. These are usually quite difficult, but a nice change from the typical lecture style classes.

The main difference is the types of electives that you take:
H. Bio = a lot more choice in electives and the courses that you don't have to take. You aren't required to take the second organic chemistry.
I would take a look at the Genetics, Biodiversity, and Physiology course lists and see what you like the most:

I've heard that Biodiversity is great if you really like plant studies and ecology. I don't really talk to anyone in genetics, so I can't help you there. The key is to enroll in a program with courses that you know that you'll enjoy.

I don't think it's particularly hard to get into any of the programs (as long as you have a 9.5.. but if you're lower than that it shouldn't be a problem), they're apparently limited enrollment but I switched into my specialization during the summer and it wasn't an issue. If you're concerned about not getting into any of the programs, the Science office in BSB 129 (I think) is really good with counselling with what program you should go into, etc. If you can, try to talk to Rita Campbell, she's so knowledgeable.
: ) Hopefully that helps!
