I found a great little shop in Kensngton market called Tutti Fruitti.
Thet have the best prices on vitamins and tinctures that I have ever seen in Toronto. One example is the sell 15 packs of Bio K for $30.00 or a single one for $2.30!! Comapired to Noah's at $3.50 for one.. It is a steal! They also have the Holistic Horizons Bowel Cleanse..... and some other hard to find goodies!
