Female firefighter in Ontario

I’m 19F and wondering if it is completely unrealistic for me to look at this career as a 5ft2, ~120lbs, female. I’ve been struggling to find a path for me and just assumed it wouldn’t be possible for me to become a firefighter. I want to work and am willing to work hard, I could sit at a desk all day but I’d be much more fulfilled doing physical work. People have always commented on how strong I look (not that this determines anything), and I was always one of the stronger girls in my classes.

If this is possible, how could I go about it?
