What Ontario asks of a business online

Putting your business online does not change the rules, but a few rules are worth checking:

• In Ontario, you need to register your sole proprietorship if you are not using your own name as your business name, and a business name registration is valid for 5 years. Ontario.ca: business names
• The Ontario Business Registry lets businesses and not-for-profit corporations complete over 90 transactions online, including registering, incorporating and updating their information. Ontario Business Registry
• Since January 1, 2021, the AODA has required a business or non-profit organization with 50 or more employees to make its public websites accessible: web content posted after January 1, 2012 must meet the WCAG 2.0 Level AA success criteria, with some exceptions.
