Canada's Senate endorsed the Kyoto Protocol in a voice vote on Thursday night, clearing the way for the Canadian government to formally ratify the agreement , local press reported Friday.
The ratification of the 1997 United Nations' pact on greenhouse gases now requires only the signatures of Prime Minister Jean Chretien and four of his cabinet ministers.
Canada's Commons endorsed Kyoto Tuesday after months of wrangling between the federal government and the provinces.
Canadian Environment Minister David Anderson is expected to personally deliver the signed ratification documents to the United Nations in New York next week.
The next major step on the Canadian parliament is expected in February, when a federal budget will have to start providing the first installments of the estimated 1 billion Canadian dollars (about 660 million US dollars) in eventual direct annual costs for the implementation.
