Not all Canadian schools require GREs. I'd check out each school individually, but I do know offhand that Ryerson doesn't need GRE scores, and that Waterloo does. In terms of MSc vs. PhD, many Canadian schools still expect students to complete a masters before their PhD. That said, the schools that do consider direct-entry PhD only do so for exceptional candidates (I know at the University of Toronto, this means GPA >3.85). So with your stats, it might be better to focus on MSc applications, and programs that don't require GRE scores. Hope that helps!

I just gave it a quick glance over, but it seems a little too 'past oriented' - you focus on your accomplishments to date, like a retelling of your CV, rather than your interests for the future. Try to focus on how each experience shaped your future research interests, rather than just listing off the things you have done. I'd also bring up what your research interests are sooner, and maybe address what you hope to do (specifically, if possible) during your Masters program and beyond (as a career). Lastly, I'd get rid of the quote at the beginning - it bears little relevance to either your opening, or your field of interest.
