Guelph is an amazing school academically and socially. You will be able to conduct cutting-edge research, surrounded by people who passionate, intelligent and supportive. There are so many social events and opportunities so don't be nervous to join clubs, teams or come out to social events!
I loved being a PhD student here. My advisors and labmates were all very supportive of my research endeavors. I enjoyed being in charge of my own research project.
Networking is essential when considering graduate studies. I met my research advisor at an informal chemistry meet-up in Brass Taps two years prior to working for him. You'll never know when opportunities present themselves, so it's important to take chances and meet everyone you can.
Choose a supervisor who makes you excited about your project. There will be times when your project does not go as planned and reminders of that enthusiasm and why you are doing the work are crucial to continuing through the hurtles.
If you are considering graduate studies, I suggest that you take your research interests and see who on campus is pursuing something that aligns with them. Given the wide range of topics and fields of study here, I would not be surprised to see at least one other individual or faculty member engaged in some research that closely mirrors the interests of the student.
