About W&T Mushrooms

Welcome to W&T Mushrooms Ltd. We are a family-run farm founded by Witold Jaroszewski in 1984.

Witold purchased the property with a dilapidated mushroom farm containing only two small growing rooms. The operation has since grown to six 2,000-square-foot rooms producing roughly 10,000 pounds per week.

To produce a quality product that meets our high expectations, a Dutch growing system was imported and installed to automate the filling and emptying process. It also controls each room’s temperature and humidity individually through a computerized system.

Our farm has grown oyster, shiitake, king oyster, maitake, enoki and reishi mushrooms. Today, we focus on commercial cremini and portabello production for Southern Ontario.

Creating a quality product is our passion.

Get to Know

The Farm

Located just outside Rockwood on a dead-end road, our farm includes six 2,000-square-foot grow rooms, a picking corridor, filling corridor, cooler, storage and offices.

Technology and custom-built machinery are only half the story. Mushrooms still require skilled human care throughout the day. They are mostly water and require approximately 45,000 litres each week, while growing-room conditions must remain closely controlled for an optimal crop.
