Re: McMaster School of Medicine, Hamilton, Ontario
^ there's no harm in applying... although like I said before, you'll have a better chance after you graduate with an Honors undergraduate degree. As it is, many McMaster med school students already have a graduate degree of some kind.
Also, I hope that you're volunteering / working in a health care related area already... a good GPA by itself isn't going to be enough to get into any med school.
