Make sure you need grad school for your future career before you do it. Reach out to other grad students while you're in undergrad; most people will be more than happy to share their experiences.
If I were to speak with someone considering Guelph, I would tell them that although it may not be a very lucrative venture, it is an incredibly fulfilling experience. Additionally, for those thinking about diving into graduate studies but are unsure about the difficulty or commitment, always remember: a little drive and determination can go a long way!
People are very friendly and kind, and respect each other's culture. I felt like I was at a home away from home. There is not the rush and noise that you find in most cities. Life is…perfect here.
Find what interests you. Many other grad students are much younger than I am and will be entering a life's career following completion of their studies. Looking back, I think it's important to pursue your passion and let the career, money, etc., come from that. During studies, stay on top of things. At the same time, don't neglect other outlets, pursuits, interests: things have a way of connecting in unexpected ways.
The faculty profiles page, on the Food Science Department website, is very useful to help find research projects that you may be interested in. Do not hesitate to email or talk directly to the faculty members. They are always welcoming, and can even help you apply for scholarship funding!
My advice would be that a Masters degree is like a roller coaster. You will have your ups and downs in your research but that is all apart of being a scientist! There is no such thing as a 'bad' discovery.
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.
