In terms of the two-year patent term restoration, as I understand it, if a patent rights-holder applies for a drug to get regulatory approval in Canada, the length of time it takes to approve that drug currently counts against the time they can market it free from competition, so they question why they should have their patent term eaten up by a slow regulatory process. You pointed out that the extension of up to two years would apply, even if they themselves are guilty of the delay.
