In the risk-based approach that is in place for crop protection products, it is the company, it is the technology developer, that undertakes the studies that are mandated by government, and then government evaluators will take a look at that data and make the assessment. It's still the technology provider that is making the investment to provide the data, and then an independent body of scientists, PMRA, and under global joint review, this workload is shared with the EPA and other agencies that are part of the global joint review will take a look at that. In areas where it is unique to Canada, such as environmental, then clearly Canadian regulatory officials need to take a look at it.
How I would differentiate between a risk-based approach and a hazard-based approach is that the key difference is this exposure, as we talked about earlier. Many substances can be a potential or known hazard, but what is key is to understand the exposure to that hazard to understand its risk.
