I mean, I'm sorry to break this to you but if you're good at data science or complex backend web development it's pretty common. I was making around $225k CAD a year (straight cash, not counting options) at 500px a decade ago when it was around 35 people. Now nominally I was Chief Data Scientist and it included some IP from my two person startup they acquired, but it was an aquihire and everyone knew it. I had just turned 27.

Look for startups funded by pro investors with deep pockets that operate in Canada and negotiate with a willingness to walk away.
