The program at Con-Mac does not have a way to specialize, however in 3rd and 4th year you have a say in where you do your clinical placements. As lalaxton said, you can guide you learning to where you want to go. I encourage you to keep you mind open - I though I knew what I wanted to do when I started nursing school (L&D) and ended up in a whole different area (trauma) and then came into teaching (here at Conestoga). There is a whole world of opportunity - do not put on blinders, you may lose some excellent experiences.
If you really want to do something over the summer, check out your basic anatomy & physiology and look at Problem Based Learning (PBL) which is the method of study in this program. PM me if you want more info.
Good luck - enjoy your summer and drop by to see in the Clinical Learning Centre when you get here!
