British Columbia is the second largest mushroom producing province in Canada, after Ontario.

The main crops are different sizes of white-and-brown coloured strains of Agaricus button mushroom. A few specialty mushrooms are also produced and sold mainly to local restaurants. The Agaricus button industry has a reputation for growing high-quality fresh mushrooms.


Mushrooms require compost to grow. Compost contains carbon sources that come from straw and from animal manure that contains residues of vegetable matter used as animal feed. About 2,000 cubic yards per week of dry poultry waste is used in mushroom media production, which plays a large and beneficial role in reducing excess nutrient load in the Fraser Valley.
