It's difficult to say whether the legislator intended to create confusion. However, the bill certainly creates confusion between the notion of national interest used in the bill and the notion in constitutional law.
We often hear the phrase “national interest”. A number of years ago, former prime minister Paul Martin said that child care was of national interest. We must be careful. In constitutional law, matters of national interest are clearly defined by the Supreme Court. These projects go beyond provincial interests in well‑defined matters or issues, and are clearly distinct from provincial jurisdictions. However, the current bill doesn't seem to meet these conditions. It still carries a significant risk of being overturned by the courts, given the reference regarding the Greenhouse Gas Pollution Pricing Act and the most recent reference regarding the Impact Assessment Act, which was struck down in part.
