That's a complicated question, and I don't think anybody has the complete answer to that yet. A huge number of factors affect bee health—habitat loss, parasites, diseases of bees, management of hives, and pesticides play a role in acute deaths—but I don't think we actually have a complete answer to what all is contributing to pollinator health. The Senate's doing a big study now.
I think it's a combination of a number of factors that are leading to the current situation. I think in Canada we haven't seen any widespread reductions in colonies, or reductions in the number of beekeepers or in honey production. It's very local, as Pierre said. It's targeted at some very concentrated areas with a couple of crops. We just aren't seeing those kinds of deaths associated with canola production. Canola production and bee production seem to be thriving equally in the western provinces.
We believe there have been some problems with acute incidents that have been largely rectified by changing formulations of seed treatments and by changing agronomic practices, but in terms of overall pollinator health, it's very complicated in terms of what is actually causing deaths when we see colonies collapse and things like that.
I would probably defer to Pierre for more of the science—
