Initially we started on the environmental aspect for oil spills, and we worked with the Canadian Coast Guard, Environment Canada, and it was strictly for oil spills.
There was a huge change in Canada's policies regarding oil spills, and the Canadian Coast Guard started outsourcing work. They are no longer a responder; they are simply an observer. They don't respond. It has gone to private industry. So to have a suitable business model that would make sense, we had to go and look at something where there was a daily occurrence of a spill. The oil sands industry invited us to take a look at tailings.
