An audit released by the Auditor General of Montreal on August 25, 2026 shows that the city is still sending the majority of its solid waste to landfills, falling short of the 15 percent diversion target set for 2030. With less than four years remaining before the deadline, the findings indicate that Montreal is not on track to meet the goal that would limit landfill waste to fifteen percent of total waste generated.
The report examined municipal waste‑management data for the past several years and concluded that despite the city’s public statements about reducing landfill dependence, most of the material collected by the city’s recycling and collection services continues to be disposed of in landfill sites. The audit did not provide a precise current landfill share, but emphasized that the share remains well above the fifteen‑percent ceiling.
City officials have previously outlined a strategy that relies on expanding recycling programs, increasing composting capacity and encouraging residents to separate waste more effectively. The auditor‑general’s analysis, however, suggests that implementation of those measures has not produced the expected reduction in landfill volumes.
Montreal residents are likely to feel the impact of the shortfall as the municipality may need to consider additional actions to accelerate waste diversion before the 2030 target date. The audit recommends that the city provide clearer performance metrics and strengthen enforcement of existing waste‑separation rules.
The Auditor General’s office said the findings will be presented to the city council and may prompt a review of current policies. The report adds pressure on municipal leaders to adjust their approach as the province’s overall waste‑management objectives align with the 2030 target.
