It sounds like you're considering Cornell's graduate program in veterinary medicine.
Are you a realistic candidate? Take the Graduate Record Exam along with the Biology specialty. You can also take the Medical College Admission Test.
Then, when you have your scores in hand, call them and ask them. They'll tell you. At the graduate level, admission decisions are more straightforward than for undergraduates. There isn't as much focus on Chess Club type stuff.
They probably don't get many applicants from Nova Scotia, so they may not know a lot about the St. Mary's biology program. That's OK, though. If one of your professors can take time to write a letter of recommendation that explains the program, you'll help them evaluate you fairly. You can also write a letter yourself explaining the program.
One tip: don't let your heart become too fond of one vet school. They don't have enough places for everybody who wants to be a vet, so you may not get in to your first choice. I had a college pal who wanted to go to vet school. But she didn't get in so she had to settle for (human) medical school.
