Read the guide ↗Each guide is written by the BMD Legacy team for business owners rather than accountants. The Ontario guides are checked against official sources, such as the Canada Revenue Agency and the Government of Ontario, and each one shows the date it was last reviewed. They explain the general rules: your own deadlines and obligations depend on your business, so confirm them in your CRA account or with your adviser before you act. If you would rather not keep track yourself, our Canada team can take care of the bookkeeping and filings for you.
