Direct peers

• GFL Environmental: GFL is one of Canada's largest diversified environmental services companies, offering solid waste, liquid waste, organics, and resource recovery. Direct overlap with Walker's waste disposal, organics recovery, and biosolids lines, and the most direct Canadian comparable by business mix and customer profile.
• Miller Waste Systems: Privately held Ontario-based waste management company with collection, transfer, landfill, and organics operations — directly comparable to Walker Waste Services and a recent counterparty in Walker's 2026 Escarpment Renewables acquisition.
• Tomlinson Group: Ottawa-based family-owned environmental and construction services company with aggregates, asphalt, ready-mix concrete, and waste hauling — directly overlapping Walker's vertically integrated construction materials and waste disposal model in Ontario.

Broad incumbents

• Waste Connections: Large North American solid waste services platform with significant Ontario presence; competes directly with Walker in landfill and transfer station operations, and serves similar IC&I and municipal customers.
• Republic Services: U.S.-headquartered environmental services leader with landfill, recycling, and organics lines. Broad incumbent providing benchmarks for Walker's scale and operational model, though primarily competing in different geographies.
• Waste Management, Inc. The largest North American waste services company and the de facto benchmark for landfill gas-to-energy and organics processing economics; not a direct competitor in Ontario but closely comparable in operating model and RNG strategy.
• CRH plc (Canada operations): Global aggregates and building materials leader with Ontario operations; directly comparable to Walker Aggregates and Walker Construction on the construction materials side of Walker's portfolio.
• Clean Harbors: North American leader in hazardous waste and environmental services; comparable to Walker's hazardous waste handling (e.g., asbestos disposal at Niagara) and broader environmental services scope, though with a heavier industrial focus.

Emerging players

• GreenForges: Canadian emerging player in subsurface geothermal and resource recovery intersecting with Walker's landfill gas and renewable energy strategy; small but adjacent technology player in the broader circular economy space.

Regional players

• Halton Region (in-house operations): Municipal peer/customer in waste management — Halton operates waste programs in the same regional market where Walker operates commercial waste drop-off; not a private competitor but a relevant comparable for contract structure and unit economics.
