What Is a Nutrient Management Strategy?
A Nutrient Management Strategy (NMS) is a regulatory document required under Ontario's Nutrient Management Act (O. Reg. 267/03). It focuses on how nutrients are generated and stored on your farm — particularly related to livestock housing, manure storage, and farm expansion.
If you're building a new barn, expanding your livestock operation, or increasing nutrient storage capacity, you will likely need an NMS before construction can begin.
When Do You Need an NMS?
Building a new livestock barn
Expanding an existing barn or livestock operation
Increasing manure storage capacity
Your operation generates 5+ nutrient units
Construction of new or expanded nutrient storage facilities

Timeline
The NMS process typically takes several weeks from initial farm visit to final OMAFRA approval. Starting early is critical — delays can cost you a full growing season. See detailed timeline.
Cost
Cost varies based on the size and complexity of your operation.
