One of Canada's leading voices on environmental issues over the last half century says environmental rights for all Canadians should be enshrined in the Constitution.
David Suzuki says working to see that done is now the "last great fight" of his life.
The 80-year-old says that's the only way to ensure environmental policies cannot be overturned with the hottest political flavour.
He's pointing to the outcome of the US presidential election and says it's a real warning that something deeper is needed to protect against the fluctuations that come with political change.
U.S. president-elect Donald Trump has called climate change a "myth," and said the concept of global warming was "created by and for the Chinese in order to make U.S. manufacturing non-competitive."
Suzuki says he likes Prime Minister Justin Trudeau's environmental talk, especially his commitment to the Paris Agreement, a new climate deal signed by 195 countries that calls for limiting
the temperature rise since the industrial revolution to below two degrees Celsius.
But he's questioned Trudeau on pipelines and says he told the prime minister the Paris targets can't be met if pipelines are built.
