GFL Environmental is a North American waste services company with vertically integrated operations that collect, haul, transfer, recycle, and dispose of waste. It owns and runs a network of transfer stations, material recovery facilities, landfills, and liquid-waste treatment plants to control processes and costs. Revenue comes from municipal, commercial, and industrial service contracts, tipping fees, and sales of recovered recyclables; solid waste is the largest segment, with liquid waste management also serving hazardous and non-hazardous materials, and soil remediation was divested in 2025 to focus on core activities. The company grows by acquiring other companies to build market density across Canada and the United States, and its goal is to provide reliable, cost-efficient waste services at scale while reducing debt and expanding its solid waste footprint.
