This country's government is now behaving with all the sophistication of a chimpanzee's tea party. So amazingly destructive has Canada become, and so insistent have my Canadian friends been that I weigh into this fight, that I've broken my self-imposed ban on flying and come to Toronto.
So here I am, watching the astonishing spectacle of a beautiful, cultured nation turning itself into a corrupt petro-state. Canada is slipping down the development ladder, retreating from a complex, diverse economy towards dependence on a single primary resource, which happens to be the dirtiest commodity known to man. The price of this transition is the brutalisation of the country, and a government campaign against multilateralism as savage as any waged by George Bush.
Until now I believed that the nation that has done most to sabotage a new climate change agreement was the United States. I was wrong. The real villain is Canada. Unless we can stop it, the harm done by Canada in December 2009 will outweigh a century of good works.
In June this year the media obtained Canadian briefing documents which showed the government was scheming to divide the Europeans. During the meeting in Bangkok in October, almost the entire developing world bloc walked out when the Canadian delegate was speaking, as they were so revolted by his bullying. Last week the Commonwealth heads of government battled for hours (and eventually won) against Canada's obstructions. A concerted campaign has now begun to expel Canada from the Commonwealth.
The purpose of Canada's assault on the international talks is to protect this industry. This is not a poor nation. It does not depend for its economic survival on exploiting this resource. But the tar barons of Alberta have been able to hold the whole country to ransom. They have captured Canada's politics and are turning this lovely country into a cruel and thuggish place.
