Proof? Just look at public records. Many cases of willful negligence the cause for many spills. Yes, many. Over 400 since 2003. KM has a history of having to taken to court to live up to their cleanup responsibilities.

I don't think most people are against jobs created, whether in BC or Alberta. Nor do they want to adversely affect people's livelihood. But the economic damage one oil spill would do to the fishing industry is also at risk.

There are other safer ways to transport oil, such as not going through coastal waterways.  It comes down to profit, and doing things where an oil spill would have less of an ecomonic impact are not in KM interests.
