In Canada, you need to file a tax return if you're a resident and your income is above a certain amount, called the basic personal amount. But even if you don’t make a lot of money, it’s still worth filing to get benefits like the GST/HST credit or the Canada Child Benefit. If you’re running your own business, getting dividends, or making money from renting out property, you definitely need to file. Also, if you're not a resident but have Canadian income or want a tax refund, you might need to file a return too.
