The Nottawasaga Valley Conservation Authority

New Conservation Authorities Act Regulations

As of April 1, 2024, NVCA will follow a new regulation under the Conservation Authorities Act to review permit applications.

The current regulation, Regulation of Development, Interference with Wetlands and Alterations to Shorelines and Watercourses (O. Reg. 172/06) will be replaced with Prohibited Activities, Exemptions and Permits (O. Reg. 41/24).

NVCA will continue to be responsible for regulating activities in natural and hazardous areas in order to avoid the loss of life and damage to property due to flooding and erosion. Under the new regulation, pollution and conservation of land will no longer be considered in permit reviews.

The permit application and review process will mostly remain the same.

There are a few changes that may affect property owners in NVCA’s regulated areas. These include:

  • NVCA will review your application within 21 days, and let you know if your application is complete, or if there is missing information. Regardless of whether a permit is minor or major, NVCA staff have 90 days make a decision on your permit application once it has been deemed complete.
  • Permits may be issued for up to 60 months (maximum validity period) including any extensions.
  • The regulated area around wetlands will be 30 m, including provincially significant wetlands. This change will be reflected in NVCA’s regulated mapping shortly. In the interim, NVCA will follow the text in the regulation.

Some projects will no longer require a permit. Expand the arrows below to learn more:

How do these changes affect my project?

Applications received before April 1, 2024

For permit applications submitted before April 1, 2024, NVCA’s Planning staff will review permit applications using the Ontario Regulation 172/06. This the regulation in effect at the time the application was received.

Under to the new regulation (Ontario Regulation 41/24), NVCA’s regulated area has changed. If the application for the proposed development is outside of NVCA’s new regulated area, NVCA will follow up with a written correspondence confirming that a permit is not required from the NVCA.

Applications received on or after April 1, 2024

For applications received on or after April 1, 2024, NVCA’s Planning staff will review permit applications under the new regulation (Ontario Regulation 41/24).

I already have my permit. Does the new regulation apply to me?

Property owners with permits issued prior to April 1, 2024, and have expiry dates beyond April 1, 2024, must follow the conditions stated on the permit until the permit expires.

Can I apply for a permit extension?

If your permit was issued before April 1, 2024, you may be considered for an extension. This includes extensions requests submitted after April 1, 2024. The extension will be considered using the new regulation (Ontario Regulation 41/24)

Under to the new regulation (Ontario Regulation 41/24), NVCA’s regulated area has changed. When reviewing your extension request, NVCA will consider if your development activity is located within NVCA’s new regulated area. If your it is outside of new NVCA’s regulated area, NVCA will provide a written correspondence confirming that an extension is not required.
