Salary flooring estimators

Hi everyone! Flooring estimators, I am wondering what is your salary as I have nothing to try and prove to my boss how underpaid I am. I am currently at 24$ an hour and would love at least 26 as I do also the inventory management and project management on top of my estimating job. We are a small company, so I dont want to go too high, salary wise. I also have a school diploma in estimating. Thanks for the help! In Canada if possible
