I want to start my own fishing charter. I need to know where to go to register a company name, and a GST number? And anything and everything there is to know like what I need to have and what is the best secure way to go about starting a business.

You will have to visit the Canadian government website for all of this information Government of Canada Site | Site du gouvernement du Canada (http://www.canada.gc.ca) and only maybe the best way to start a business, as the government site may have tips for new business owners. I am assuming though you are from Canada because you did inquire about the GST which is goods and services tax.
