Open Environmental & Waste Tenders in Ontario — 78 Live Today
Data updated September 28, 2026
Environmental and waste contracts in Ontario come mostly from municipalities and regional governments: curbside collection of garbage, recycling and organics, transfer station and landfill operations, household hazardous waste programs, and environmental site assessment and remediation — alongside forestry and wildfire risk-reduction work from provincial agencies.
Collection and processing contracts often run for several years, so each re-tender is a rare opening in a local market. The open environmental and waste opportunities in Ontario are listed below with buyers and closing dates.
