NMS Timeline: How Long Does It Take?
One of the most common questions we hear: how long does it take to get an NMS approved? The honest answer is it depends — but here's a realistic breakdown.
Typical Timeline
From initial farm visit to final approval, most NMS projects take several weeks. This includes on-site assessment, nutrient calculations, plan preparation, and OMAFRA review.
What Can Cause Delays?
Incomplete information, complex operations, or seasonal backlogs at OMAFRA can all add time. Starting early is the best way to avoid delays.
The Bottom Line
Don't wait until you're ready to build. Starting your NMS early gives you the best chance of staying on schedule. Delays can cost you a full growing season.

Frequently Asked Questions
Do I need an NMS to build a barn in Ontario? In most cases, yes — if you are increasing livestock or nutrient storage capacity, you will likely need a Nutrient Management Strategy (NMS) before construction can begin.
What are nutrient units? A nutrient unit is a measurement used under Ontario's Nutrient Management Act to determine the regulatory requirements for your farm. It's based on the type and number of livestock you have.
When do I need both an NMS and an NMP? Typically when your farm operation exceeds 300 nutrient units, you'll need both a Nutrient Management Strategy (NMS) for storage and expansion, and a Nutrient Management Plan (NMP) for land application of nutrients.
How long does approval take? Approval timelines vary depending on the complexity of your operation. Most plans take several weeks from farm visit to final approval. Starting early is critical — delays can cost you a full growing season.
