We have to be very careful that we don't regret our developments in a few decades because of the rapidly changing conditions we have.
Something you mentioned was road development. Road salts are heavily used in southern Ontario. They are in fact making the recovery of Ontario's lakes much more difficult, because they cause stratification of the water, and therefore more phosphorus is trapped in there and there are more algae blooms. This is recent science that came out of the University of Waterloo.
These results, and mitigation measures, have to be taken into consideration in these developments. How can you develop the road without having those impacts? This is something that Canadians have worked on for a long time, and I think it can be done, but we have to be planning for the hydro-climatic conditions of the mid-21st century, not for the mid-20th century, and that will be crucial for those things.
