Glyphosate formulations, which include both the active ingredient and other formulation ingredients such as surfactants and solvents, are assessed by the PMRA for their hazard and the risk they may potentially pose to human health under actual conditions of use. The Pest Management Regulatory Agency (PMRA) only approves those products, which do not pose an unreasonable risk of harm to human health or the environment.

In Canada, all components of the formulation, including the non-active ingredients such as the emulsifiers and solvents, are subject to health hazard and risk assessment and regulation by the PMRA. And the same PMRA safety threshold of “reasonable certainty of no harm” (PMRA , 2015
In April 2015, the PMRA released their latest review of glyphosate and declared that the weight of evidence indicates that glyphosate does not present unacceptable risk to human health.
