I'm going to add one more vote of support to the chorus. I have been living close enough to walk to Kensington for over a year now, and since then I have only been to Loblaws a handful of times.
Essence of life has so many great products and the pricing is great. Compared to organics sections at large grocery stores, it's much better, but even compared to other specialty organic shops it comes out on top. It is usually my first stop on my grocery run (which takes me to Global Cheese, Market Bakery, Sannagan Meats and Oxford Fruit).
The only disadvantage for those who don't live close is that it's hard to park. There is a green P parking lot a couple of streets over to the west.
