I am a BScN student in Ontario, so I'm obviously biased about this topic.
I would recommend the university education for a few reasons:
1. If you ever decide that nursing is not for you anymore and you head back to school, you can use your previous university credits towards some of your program requirements (as electives).
2. There is a lot to learn in nursing, and I think (my opinion) that you learn more in a longer time span - even if it is not more information presented, you learn more because you have longer to assimilate that information.
3. If you look at a job board for your area (Try workopolis) you will see that there are more jobs posted for RNs than RPNs.
4. RNs work in more areas, so an RN education gives you more options to find your special niche.
5. Once you are working as an RN, you can train for a specialty area
6. More education can never be a bad thing.
7. If you decide you want to go further with your nursing education (e.g. Master's degree/nurse practitioner) a BScN is the entry level for that.
If you have questions, you can read this publication by the College of Nurses of Ontario.
It's the best I could find to show the differences in RN and RPN roles in Ontario. The chart is especially helpful. If you still have questions, I suggest getting in touch with the CNO.
Good luck with your decision.
PS - In Ontario there are no LPNs (Licensed Practical Nurses), so that's one less thing for you to worry about!
