I wrote twice to Cauchon (the previous Justice Minister), without getting a reply. I wrote to Cotler's Montreal office in January, and got a reply from someone there simply saying that they forwarded my letter to Ottawa - where I assume it was also ignored.
However, Cotler does have a "human rights" background, and he praised the Pivot report when making a speech to UBC law students, and said it was time for the 3 levels of government to change the laws to protect sex-trade workers. That sure sounds as though he likes the idea of decriminalization.
I guess the lack of a reaction from the media shows people's attitudes may have changed in Canada. Not long ago any politician backing decriminalization would be called crazy. I guess the examples in Europe, Australia, and New Zealand help show it's a realistic idea. The obvious tolerating and/or licensing of escort agencies, MPs, and incalls also show that the existing laws have become insignificant and must be reformed. And if the laws are declared unconstitutional, the politicians will be forced to make decisions instead of ignoring this matter.
