When we had the OMAFRA office doing research they gave an unbiased opinion. "Now when we go for our seed, who do we have to rely on," Renaud wonders. Renaud adds that OMAFRA is putting an end to "third party research," leaving the companies actually making the product to do their own research "rather than Guelph University." She says it means for individual companies "your results can be whatever you want them to be.” --Ellie Renaud, Provincial Director in Leeds County for the Ontario Federation of Agriculture.
