The Canadian voluntary 4R Nutrient Stewardship Certification Program certifies nutrient service providers in the Western Lake Erie Basin, across Ontario and in Prince Edward Island (PEI), that apply or make recommendations on fertilizers in accordance with 4R Nutrient Stewardship principles (Right Source @ Right Rate, Right Time, Right Place). Program participants must go through an independent, third-party audit of a set of standards to demonstrate they not only understand 4R principles, but also follow them.

The 4R Certification program was first brought to Canada through implementation of the program in Ontario in close collaboration with the Nutrient Stewardship Council, the Ohio AgriBusiness Association and The Fertilizer Institute in the U.S. to ensure alignment between cross-border efforts.

The 4R Certification Program is funded and guided under a 4R Ontario Steering Committee comprised of a diverse set of stakeholders from industry, government, conservation authorities and grower organizations including Fertilizer Canada, the Ontario Agri Business Association (OABA), Grain Farmers of Ontario (GFO), the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA), the Ontario Federation of Agriculture (OFA) and the Christian Farmers Federation of Ontario (CFFO) and Conservation Ontario.

The PEI 4R Certification standards were developed by Certification Working Group and Steering Committee to create a set of standards are representative of PEI agriculture, landscape and nutrient loss pathways of concern. The standards are reflective of the best available science, technology and regulatory requirements for PEI conditions. Members of the 4R PEI Steering Committee represent a diversity of stakeholders including Fertilizer Canada; the PEI Ministry of Environment, Water and Climate Change; the PEI Ministry of Agriculture and Land; the Atlantic Fertilizer Council; the PEI Potato Board; the PEI Federation of Agriculture; the Kensington North Watersheds Association; and PEI agri-retailers.

This program is administered by Fertilizer Canada. To learn more about 4R Certification or to schedule an audit in Canada, visit or contact McKenzie Smith at msmith@fertilizercanda.ca
