Hi Peri,
This is indeed a bit of a confusing area. I would recommend that you watch the Herbal Business course, read through all of these comments and perhaps read through the Natural and Non-prescription Health Products Directorate (NNHPD) if you want more detail.
But to keep it incredibly brief, as long as you do not make any health claims on your labels or in the names of your products and you remain small (direct selling at farmers markets and online) you will likely be fine not to register them through Health Canada.
This process is long and too expensive for a small sole proprietorship type business really.
Wishing you smoothness and creativity with the creation of your products!
