You can do front end developer contract gigs on one of the freelancer sites. You won't make a ton but you can make 2 or 3 times minimum wage (based on Vancouver minimum wage) without trying very hard. You can make a good bit more than that if you get good at contracting. Plus contracting lets you build skills you won't get working as an employee.

Work 4 months out of the year full time, or 10-15 hours a week year round and you'll make as much as you would working at McDonald's. Spend the rest of your time learning whatever you want.
