Madam Speaker, as my hon. colleague heard me say in my remarks, it is not knowable what the cost will be yet, because many jurisdictions have yet to devise a system. There is a deadline in place, in September, when all the jurisdictions in Canada will have to have their pricing schemes in place. Otherwise, that will be backstopped by a federal process, but we cannot know those costs until that deadline arrives.
I would add, to revert back to my development charge analogy, that as with development charges, for carbon pricing or pollution pricing, there are some things we know the cost of, such as carbon capture and so forth, but there are many things we have a very hard time putting a figure on, like the impact on the health of our children, for example, or on the ecosystems around the world. These are things that are going to emerge as we understand what the jurisdictional programs look like. At that time, we will be able to understand the cost and the benefits much more clearly.
