How to register a business

Hello everyone, I'm hoping to run a business in Ontario. Is there anyone here who can walk me through the steps of starting a business in Ontario? In Ontario, who is eligible to register a business, and what are the limitations to start one? Do you have any limitations? Can I use my name as the company name? If someone could assist me with this, that would be fantastic. I came to read this blog on how to register a business and was very informative. Please leave your thoughts on this and provide any suggestions. Thank you.
