Comment American Pressure did it. (Score 2) 121
I think the reason this was done was because of american diplomatic pressure. The US state dept has classified Canada as a 'pirate country' right up there with China, and other countries that make billions from counterfeit knock-offs just because we have different copyright laws. Further, the US has pushed hard, and successfully to have the the 70 yr term included in the new (quasi secret) Trans Pacific trade treaty. None of the other countries wanted that term but the US got it in there anyway. Canada finds it very difficult to do things the US is strongly opposed to; and once the Treaty was approved we would be stuck with 70 years anyhow. This is very much a case of 'Resistance is Futile' and the Borg is the US state department.
