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.
Try your best to reach out to faculty and make connections with people who share the same passions as you. Everyone at the University of Guelph is happy to share their expertise and provide guidance, and those connections are very valuable in expanding your knowledge and reaching your goals.
Although I think most prospective grad students have been told about the importance of picking a study/project that interests you, I think it's also really important to take some time to see how you interact with your supervisor and lab. These will be the people you work the closest with for the next several years, and help provide support to you in some of your toughest moments.
Professors at the University of Guelph are exemplary in their professional acumen. Over and above this, there are plenty of opportunities, like Teaching Assistantship (GTA) and Research Assistantship (RA), for an international graduate student to help fund their studies.
Absolutely take the time to reach out to current students, alumni, and faculty members affiliated with the grad programs of consideration. Your grad school experience will very much be influenced by the people you are surrounded by during your education and the culture of the program. Hearing from other's experiences and talking to current students is one of the best ways to find the right fit for you.
I believe that one of the keys to success in terms of graduate studies and beyond is to be passionate about your work; this makes the dedication required to do well come that much easier.
