Policies and Guidelines

Under Ontario Regulation 162/06, Conservation Halton regulates development in spill flood hazards (“spills”). Spills occur when floodwaters leave a watercourse, its valley and floodplain, and continue to flow overland in multiple directions before rejoining the same watercourse downstream or spilling into another watershed.  Spills often move through areas where riverine flooding may not be anticipated and can flow in complex patterns.  Conservation Halton has an interim policy for development in spills but is undertaking a review and update of this policy.  

In March 2022, Conservation Halton shared a discussion paper as the initial stage of the spill policy review and update process to provide the public and stakeholders with background information on spills and to engage on the policy approaches that CH could take to deal with development in spills. In November 2022, Conservation Halton’s Board of Directors endorsed the Spills Flood Hazard Policy Report, which includes an overview of the feedback received on the discussion paper and staff’s recommended policy approach/direction for managing risk associated with development in spill flood hazards along with supporting rationale.   

Throughout the policy review and update process, Conservation Halton will engage with other conservation authorities, municipal partners, residents, and other stakeholders. Conservation Halton staff will assess the input received throughout the process, draft new policies, and recommend to the Conservation Halton Board of Directors on the approval of any new spill policies. A public engagement session to present draft spill policies and engage further is anticipated to occur in Winter 2023.
