Toronto, Canada.https://hdl.handle.net/10315/43681This report was written for Above Ground (https://aboveground.ngo/) and will also appear on the organization's website.This report analyzes the impact of mandatory Human Rights and Environmental Due Diligence (mHREDD) on Canadian competitiveness through a systematic review of academic and policy literature. It finds limited direct empirical evidence but identifies key mechanisms shaping competitiveness, including compliance costs, supply-chain restructuring, regulatory fragmentation, and governance design. Evidence suggests no systematic negative effects on firm profitability, while benefits include improved market access, investor confidence, and supply-chain resilience. Impacts are highly design-dependent, with leaders gaining advantages and smaller firms facing higher burdens. Overall, aligning Canada with global mHREDD regimes may enhance its position as a trusted and competitive trading partner.enHuman rightsEnvironmentSupply chainReport
