Our Farm
Weth’s Mushroom Farm near Goderich Ontario
We have been growing fresh exotic mushrooms on our farm for 25+ years and shipping them to clients in Ontario and Quebec. However, many locals don’t even know we even exist!
Being separated for too long from the people who love our mushrooms, we’ve decided to open the farm and share some of our fresh-grown mushrooms and show you more of what we do.

A brief history of Weth Mushrooms


Weth Mushrooms Inc. is a family farm independent business currently run by husband-and-wife team Ryan and Susan Weth. Mushroom farming has always been labour of love, and it would not be possible without the great employees that support the skilled operation of our business.
The property of Weth Mushrooms Inc farm was founded by Ryan’s father Tom in 1999 with the goal of retirement. It all came about by a chance meeting with the past property owner. Familiar with unique area of the Maitland Valley from many summer holidays, he jumped on the chance to purchase the property.
Tom had a family history in manufacturing sector and enjoyed keeping busy outside of work. Looking to ease into retirement, Tom was encouraged by his son’s interest to start a low impact, forestry science-based business.
Ryan was looking for a small footprint to start his business but after seeing the attributes of the property, the idea of growing mushrooms from initial culture to packaged product scale was realized.
Shortly thereafter Ryan was lucky enough to meet Susan and with her multidisciplinary experience in the food business, a supportive partnership in life and business took hold. Susan and Ryan dealt with many challenges over the first years, including Tom’s health. In 2007 the business was incorporated and the purchase of the property from Tom was finalized.
Today, Weth Mushrooms Inc. is an intensive indoor growing facility covers over 10,000 square feet. Mushrooms are grown all year round and harvested by hand every week of the year. The farm has its own spawn, growing medium production, incubation and growing rooms enabling the production of premium quality 100% Canadian mushrooms and products.
We have been certified organic by Pro-Cert Organic Systems Ltd since the start of the operation and hold Canadian Organic Regime (COR) status.
