Work for the government. Work for a school or school system or for the local assembly of elected representatives if you really want the summers off.

There are plenty of clock punchers but typically they don't job hop. If you're not OK working for years, often more than 40 hours, at some company that will eventually become big enough to not be a startup, to accrue enough internal knowledge to have value even when you don't work, you are never going to get to the 40 hours a week long vacation stage. The alternative is the public sector. In academia, you don't get the summers off (research doesn't stop) but it does significantly slow down often for months at a time and you have some variability(based on funding schedule) about what you work on, so that's another option.

(Also, you're in Canada. You can get a seasonal non-tech job and code in the off season. People find "full time dev who quits every 9 months" weird but they'd find "full time contractor who is a rafting instructor/diver/park ranger/snowmobile tour guide and codes to fund their lifestyle, so don't schedule them in the summers/winters" mostly cool.)
