When we received notifications for certain aquatic organisms we relied on DFO's fish science expertise to do that assessment. I was in Environment Canada when this was done. Environment Canada administers the reception of the notification; we take a look at its completeness; we have an MOU with DFO that establishes roles and responsibilities. We take care of their science knowledge, their expertise in that area, and from that they do the assessment. We work with them, we explain how the regulations work so the assessment is framed within the context of the regulations, and then we implement the next steps as we move forward. But in that case we rely on other government expertise.
