What Is a Side Hustle? (Definition, Examples and How to Start)
Quick answer
A side hustle is paid work you run alongside your main job or studies — part-time, self-directed, and built around skills you already have. It differs from a hobby because it earns money and from a startup because it stays small and low-risk by design. Start by picking one skill, making a simple offer, and finding your first customer within two weeks.
What counts as a side hustle?
Anything you get paid for outside your main job: freelancing, tutoring, cleaning, reselling, dog walking, digital products, driving for a platform, or selling templates made with AI tools.
If money changes hands and you chose the work yourself, it's a side hustle.
How is a side hustle different from a business?
In mindset more than paperwork. A side hustle is deliberately small: low cost, low risk, run by one person in spare hours. Some side hustles grow into full businesses — but they don't have to.
Legally, once you're earning, the same tax rules apply as any self-employed work. Our Canada tax guide covers the basics.
How much money do I need to start one?
