I'll draw to the attention of my colleague the human rights treaty signed on May 27 by both Colombia and Canada in Bogota at 11 a.m. Bogota time. And that's a binding agreement on both Canada and Colombia. The amendment, which my colleague has a copy of, refers to that agreement. But it's a binding treaty with the same powers of a trade agreement or any other agreement between two sovereign countries.
On June 1st, 2010. See this statement in context.
