How important is rank?

I am going to be a Junior next year, and my current GPA, Class rank, etc thus far is - 3.82 Weighted, 3.7 unweighted. Freshman year was not one in which I did well in, I ended up with a 3.33 unweighted, and I had taken a total of 3 honors. This year I took 4 and ended up with a 4.0 unweighted. What worries me though is that I am ranked 83 out of 420 students. I was wondering if this is a big impact on whether I have a shot at a college like Waterloo, UofT, McMaster. If 83/420 was my rank when I graduate, how big of an impact would that be? I know other factors such as volunteer work, SATs/ACTs play a big role as well, I am just curious as to how big of a role rank plays in the grand scheme of things.Thanks in advance for reading!

@mathisfun23 Rank varies from school to school. Your GPA that is top 20% at your school maybe only top 40% in another. Don’t stress over your rank. As long as you are a good student, your rank shouldn’t come into play as much.
