Clark's idea to ban the export of  thermal coal from BC is dumb. All that will do is kill more Canadian jobs all under the 'green' umbrella. To address the American softwood lumber tariff do one of two thins: 1) place a large set of tariffs on US  coal entering Canada and a 'handling fee at the port, or 2) simply ban the import of thermal coal from the US. Interesting though she is only addressing this one type of coal. 

Of course doing this will certainly signal an all out trade war with the US. This may be what is needed to finally get Canada to broaden our customer base reducing the dependence on the US. This action is decades overdue especially in the lumber, mining, oil and gas and manufacturing sectors.

The American definition of ' fair' means they have a distinct advantage. Fair in other countries means fair. Yup, that is the American way. Bully, penalize, litigate, etc. They don't even bother to recognize and accept WTO rulings which do not go in their favour.
