You're absolutely right that Canada is the worst performer in the G7 since both 1990 and since 2005, the two baseline years.
What is needed is a collection of effective measures that will meet or exceed the next target. We're not in the business of setting a target. You mentioned 60% or something else, but we're in the business of assessing performance towards the committed target, which is 40% to 45%.
They need a package of measures—and it's their choice as to what the measures will be—that are effective and that will meet the target. How much they will get from each measure is up to the government to decide, but it has to be something that is at least 40%. As I said earlier, because they've tended to miss their targets over the past 30 years, they may need to aim higher and then hope to get to the minimum of 40%.
