What Ontario actually decides
Canada has no cottage food law in the American sense, and Ontario is a good example of what that means in practice. There is one tier. You may bake low-risk things like cookies, bread, brownies and fudge in your home kitchen, you tell your local public health unit that you are operating, and they may inspect you like any other food premises. No permit number goes on the label because there is no permit.
Ontario prescribes no home kitchen notice either, so there is no sentence to print. O. Reg. 493/17 fixes wording only for service club events and wild game dinners, neither of which is a bake sale. If you have seen a "made in a home kitchen" line quoted for Ontario, it came from somewhere else.
One structural quirk is worth knowing before you book a stall. Selling at a farmers market where more than half the stalls are farmers selling their own produce takes your stall outside the provincial food premises rules altogether. Which market you choose genuinely changes which rules apply to you.
The label follows the federal rules: product name, ingredients, allergens, net quantity, your name with city and province, and a best before date. You do not need a Nutrition Facts table when you sell what you made yourself at a farmers market, a craft fair or a roadside stand.
The short version
What you can sell in Ontario
Straight from the official record. Read these as categories rather than a menu, because one recipe can cross the line on its own: a filling that needs refrigeration, a pH that needs testing, or a process that needs an authority to sign it off.
- Low-risk shelf-stable baking: cookies, bread, brownies and fudge
- Jams, jellies and preserves
- Other low-risk foods your local public health unit accepts
What is outside the rule
If your product is on this list, the answer is not "ask nicely". It is a different licence, a different kitchen, or both.
- Anything needing time or temperature control, unless your local public health unit permits it
- Anything your local public health unit has not accepted as low risk
