Generally, I've found that the Open Source community is just that - a community. People who contribute to open source code often do so because they know other contributors personally, they use each other's code, or they met someone at an event who pointed them to something. You'll find that a lot of open source projects are city specific - frequent attenders of meetups tend to hear about the same projects, learn about the same companies doing open source, and contribute in the same way. Montreal is no exception. If you're interested in Open Source, it's likely you ended up one day at Notman House. If you're learning to code, it's likely you've heard of Les Pitonneux. If you're building an open source business, you might know that Shopify was cofounded by a Quebecois. If you're a gamer, you might know that Ubisoft's Prince Of Persia was made here, and that the original source code is on GitHub.
