Be prepared. Look around first and then come here. Do your homework when you're looking at programs and remember that you stand a real chance of working with OMAFRA and OMAFRA connected researchers here. They really are the best.
I heard this quote when I first started my Master's: "Your project at the end is not going to be the same as when you started". Although your overall deliverables/outcomes might stay the same, how it gets done is very likely to shift. Those who are adaptive to change, take proactive measures to complete tasks timely, and are willing to go outside of their comfort zone will be the most resilient.
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.
Make your research project/thesis something you're passionate about. If you have a great idea, take it to a professor and see if you can make it into a project.
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.
