I am glad there's change. In the past sometimes a question to a company would results in a ton of spam as they'd "assume" you would be ok with receiving their stupid updates.
I also hope Canada will implement a similar law for junk mail. So many idiots come in to my home, disregrard the "no junk mail" sign and throw a bunch of their stupid flyers. A few times I'd get back home after a rain to find a whole lot of mess on the ground with all that paper in 1000s of pieces
