A progressive group says it’s baffled that the Canadian government has worked at the NAFTA negotiating table to protect a dispute resolution system that allows companies to sue governments, estimating it has cost Canadian taxpayers $314 million. The Canadian Centre for Policy Alternatives says in a report to be published Tuesday that Chapter 11 provisions in the North American Free Trade Agreement have cost Canada $95 million in unrecoverable legal fees, calculated based on data it obtained through an access to information request. …The CCPA says Canada has been the target of more claims under Chapter 11 than its Mexican and American partners and the trend is getting worse as Canada has been sued over twice as many times as Mexico and the U.S. combined since 2010.
