Firstly, there is no "neuroscience" program. The program is called Psychology, Neuroscience & Behaviour (PNB).
The program you are referring to is a double major of PNB and Biology, and it's called
BIOPSYCH. It has it's OWN pre-reqs that are different than PNB and Biology, so you can't use the above links that someone posted.
Here are the biopsych pre-reqs.

As mentioned above, you need to take the standard life science courses (Bio 1M03, 1A03, Chem 1A03, 1AA3, Psych 1X03, 1XX3, etc. etc.). You'll need to take Psychics 1L03, but you're also expected to complete 1B03 by the end of second year as that is a requirement of the biopsych program. Biopsych is a limited entry program like PNB, and your marks in the Psych 1X03, 1XX3, Bio 1M03 and 1A03 and Chem 1A03 and Chem 1AA3 are especially important in order to be considered for entry because there are limited spots in the program.
