I'll say what nobody is willing to say out loud. Canadians are past caring about the climate when the situation in the country is poor (as they perceive it). I say this as a climate hawk who supports carbon pricing. Maslow's hierarchy applied to political priorities. That's why you see the generation most impacted by climate change making the biggest change to the Tories.
The LPC has lost the argument on climate policy by failing to make the connection between climate policy and quality of life. This is especially true when we demand lots of sacrifice from individuals (as they perceive it, because the average person doesn't understand carbon pricing and rebates) and then have record population growth of a million per year driving up emissions while imposing very little control on industry (particularly the one responsible for over a quarter of the country's emissions).
Nor do they prioritize climate policy in routine decision-making. Where is the equivalent of GBA+ for climate impact? Instead, this government seems to prioritize social policy and particularly those ideas that result in direct transfers to individuals. Even their marquis climate policy is a form of wealth transfer, with the top 20% supposedly subsidizing the bottom 80%. Meanwhile, the sat on HFR for their whole first term, put in token unding in their second term and only started on definition work in earnest in their third term. This is for a project that has the potential to reduce flying and driving. Even transit capital funding at peak ($3B) will be less than 0.7% of the federal budget.
It's hard to not feel like climate change is an excuse for this government to implement other goals or simply a talking point to win votes. And tokenism is a harder sell when people are struggling.
You might argue that the Tories will be disastrous and revisionist. And I mostly agree. But in Canada, people don't vote in new governments. They vote out the old. Poilievre could kick puppies on live TV and still get elected. That's not because anybody thinks he offers a great alternative. It's a testament to how upset voters are with Trudeau's LPC.
