I could be of more help to you in the US since I know nothing of Canadian business practices.
In general, aside from all the fish concerns, I would recommend getting and reading a book on business law at some point. There should be some appropriate to your location that are written for small or mom/pop type entrepreneurs. At some point you will need to at least consult with lawyers and accountants, though you can do a lot of your bookkeeping yourself with something like QuickBooks or Peachtree and only use the accountant as a (paid) consultant. Keeping good books is essential to your success.
Many locales have agencies that help with small businesses, and there are often evening business school classes at what we call community (2 year) colleges here. I'm guessing you have something similar in Ontario. You can have all the knowledge and passion in a field and if you can't run the business end you will have a rough go.
