it says a minimum gpa of 6 is required, so if i have a 6 would i be guaranteed to get in since it is not a limited enrolment program ?

Yes........

Read your post wrong - Yes you are correct.

I'm not entirely sure how this works BUT I'm pretty sure the fact that "enrollment is not limited" simply means that anyone with an average of 6 or above gets into the program - there is no limit on how many people are accepted. The required average to get into programs that accept a set/limited number of students will change year to year depending on the academic standing of those who apply. With Honours Life Science, this is not the case. Instead, everyone who earns an average of 6 or greater will be accepted because competition is not a factor (enrollment is unlimited). If you don't have a 6, I'm pretty sure you will be rejected but it would be worth talking to someone at in the Associate Dean of Science office (if you haven't already) to confirm.

If you don't have a 6 average, you can still get into the 3 yr Life Sci program. I know tons of people who have done this but brought their marks up in their second year to turn that into a 4 year Honours program now
