What Windmill Farms does
Windmill Farms is a privately held, Dutch-style mushroom grower operating high-tech Controlled Environment Agriculture (CEA) facilities across Ontario, Canada and Washington state. Founded in 1964 and headquartered in Ashburn, Ontario, the company produces over one million pounds of fresh mushrooms weekly using time-honored Dutch growing methods refined over decades, supported by what is described as North America's only fully enclosed organic composting facility. The portfolio spans eight fresh mushroom varieties (White, Cremini, Enoki, Maitake, King Oyster, Oyster, Chestnut, and Portobello) offered in conventional and organic, whole and sliced formats across multiple pack sizes, plus value-added Sauté Blends, Gourmet & Wild Mixes, and dried mushroom products. Four operational entities — Greenwood Mushroom Farm, Sunnyside Mushroom Farm, Ontario Mushroom Farm, and Ontario Mushroom Farm Compost — handle cultivation and substrate production.
The company serves three primary B2B segments: foodservice operators (restaurants, hospitals, hotels, caterers), retail and grocery chains, and food manufacturers/meal-kit producers, distributing across North America through wholesale channels. Revenue is generated through one-time wholesale transactions on fresh and value-added mushroom sales; pricing is not publicly disclosed. GTM motion is sales-led, reliant on direct B2B relationships and industry visibility via CEA Alliance, IFPA, and Mushroom Council memberships. In Q1 2026, Windmill Farms became the CEA Alliance's first mushroom grower member, signaling category leadership ambitions within the controlled environment agriculture sector. The company employs 251-500 people and operates without disclosed institutional investors, parent entities, or funding rounds in the available source material.

Windmill Farms competitors and assessment
Company assessmentEmerging players
- Smallhold: US-based indoor mushroom farm operator using distributed CEA microfarms to serve urban retail and foodservice. Comparable as a CEA-focused mushroom producer, but operating at significantly smaller scale and with a different geographic model than Windmill Farms.
Direct peers
- Highline Mushrooms: Canadian-owned mushroom grower with Ontario production facilities serving North American retail and foodservice customers. Closely comparable to Windmill Farms given shared Canadian base, CEA methodology, and B2B fresh mushroom distribution model.
- Giorgio Fresh Co. Major producer of fresh mushrooms under the Giorgio and other labels, with vertically integrated composting and nationwide US distribution. Directly comparable in product mix, B2B foodservice/retail channels, and indoor CEA production approach.
- South Mill Mushrooms: US-based mushroom grower and distributor serving retail and foodservice across North America, with expanded value-added processing capabilities. Comparable to Windmill Farms in core fresh mushroom production and B2B wholesale distribution.
- Phillips Mushroom Farms: Family-owned mushroom producer specializing in fresh and specialty mushrooms, including value-added products for retail and foodservice. Comparable to Windmill Farms in specialty mushroom portfolio emphasis and B2B go-to-market.
- To-Jo Mushrooms: Vertically integrated mushroom grower producing fresh, processed, and value-added mushroom products for retail, foodservice, and industrial customers. Comparable to Windmill Farms in production scale and breadth of mushroom-based SKUs.
- Monterey Mushrooms: Largest fresh mushroom grower in North America, producing white, brown, and specialty mushrooms for retail and foodservice channels. Directly comparable to Windmill Farms in core product lines, B2B wholesale model, and multi-state production footprint.
Regional players
- NatureSweet: Vertically integrated greenhouse-grown produce brand (tomatoes, cucumbers, peppers) primarily serving North American retail. Comparable as a CEA-protected crop producer serving similar retail/foodservice channels, though focused on vegetables rather than mushrooms.
Broad incumbents
- Driscoll's: Largest fresh berry producer with global CEA and conventional operations supplying major grocery and foodservice customers. Comparable as a large-scale fresh produce supplier to overlapping retail/foodservice buyers, though operating in a different product category.
- Bonduelle Group: Global packaged and fresh produce incumbent with North American vegetable operations including preserved and fresh offerings. Comparable as a broad-line fresh produce supplier overlapping Windmill in foodservice and retail channels, though not specialized in mushrooms.
