Compliance & Enforcement

Within Regulated Features

Due to the COVID-19 pandemic, the NPCA has taken measures to protect staff and public while providing continuity of services. NPCA enforcement, permitting and planning functions are continuing to operate, however there may be delays in receiving responses to inquiries or complaints due to staff restrictions and remote work locations.

Please visit our Get Involved NPCA portal where you will find a list of Frequently Asked Questions, links and resources, important announcements, and tools to ask anything that has not yet been answered. We appreciate your patience.  


Enforcement at the Niagara Peninsula Conservation Authority (NPCA) plays a pivotal role in the protection and conservation of wetlands, shorelines and escarpment areas that are found within our watershed.

The goal of the Compliance and Enforcement unit at the NPCA is to protect life and property from natural hazards such as flooding and erosion. Through the help of planning and permitting, the NPCA prevents environmental degradation and loss of significant natural features and their ecological and hydrological functions.

Compliance and Enforcement officers are given their authority from the Conservation Authorities Act and Ontario Regulation 155/06 “Regulation of Development, Interference with Wetlands, and Alteration to Shorelines and Watercourses.

Our officers inspect, and report on various files approved by the NPCA through permits. In the case of work being done without the permission of the NPCA, our officers will notify the proponent of the violation through a Notice of Violation and may lay charges if the matter is not resolved. A Notice of Violation is a letter outlining the violation and the process to have your property brought back into compliance.

Our officers carry out the following duties:

  • Provide information & education to the public surrounding the regulations and development restrictions within the watershed
  • Liaise with contractors on approved work sites
  • Inspect and investigate potential violation sites as a preventative measure
  • Resolve minor infractions through cooperation with landowners
  • Follow up on mitigation measures outlined in issued permits


I have received a Notice of Violation. What do I do next?

A Notice of Violation is sent to landowners when work has been done within a regulated area or feature such as a wetland without permission from the NPCA or in contradiction of an issued NPCA permit. The Notice of Violation is a way to alert property owners to contact the Conservation Authority to ensure that potential works on a property are done within compliance of the Authority’s Regulation of Development, Interference with Wetlands, and Alteration to Shorelines and Watercourses and specific Planning Policies.

I have some questions about what kind of development I can do on my property. Who do I speak with?

The NPCA’s Watershed Planners are very knowledgeable on the NPCA’s governing policy and can assist you with such questions.

Is my property regulated by NPCA features?

Check out our Watershed Explorer Map and see if there are any regulated features on or near your property. Educating yourself on neighbouring wetlands and watercourses is a great way to help your local ecosystem.
