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.
