"health sciences stream" in psych?

Hi! I'm currently in gr. 12 applying to utsc for the psychology & health studies program, but I'm having a hard time determining whether or not to apply for the Health Sciences Stream. From my understanding, the stream is relatively new (which could be why I'm struggling to find more info), so if any psych undergrads in either stream could help clarify the difference between the two streams I'd really appreciate it. :)
