It is however a good idea to have the list handy in case you need it for volunteer positions

For volunteer positions as a coop student? o.o

no, no sorry I should have made that more clear. Although when applying to co-op you dont need references or reference letters, I would reccommend getting a list of references in case you decide to volunteer this upcoming year. It is important to really learn what you like and be a well rounded person and volunteering really is a great stepping stone for that.

Sounds good! I'm currently volunteering at the hospital weekly and I'll be working as a rep in one of the residences. I also have a bit of other volunteering.

Even thought they are not exactly biopharm related volunteering, I hope they are ok! =D

As long as they see that you are committed to extracurricular activities and gaining practical experience... I don't think it matters if it's biopharm oriented.
