I had the same worries when finishing my basement a couple of years ago. I didn’t want to invest money into windows that wouldn’t pass inspection or keep my family safe. What really helped me was checking a
basement window size guide that broke down the measurements clearly, with examples that are actually practical for Canadian homes. Once I had those dimensions in mind, talking to contractors was much easier because I knew what to ask for and what to avoid. It saved me time, money, and a lot of back-and-forth stress.
