Ecologists are trying to get the U.S. government to invoke trade sanctions against Canada over Ottawa’s s failure to pass a law to protect endangered species.

After 25 years of having an endangered-species law south of the border, a U.S. wildlife coalition ran out of patience waiting for Canada to follow suit.

“Look Canada, you’ve got to get going,” said Bill Snape of Defenders of Wildlife. “Now is truly the time, or the president of the United States will have the authority to impose trade sanctions upon you.”

Canada promised to lead the world in protecting endangered species in 1992. A bill was introduced in 1997, but it died when a federal election was called.
