mr. trudeau,
nobody cares about deficits. and, nobody cares about free trade, either - especially not the people writing these free trade deals.
the combination of creating a domestic carbon tax without a border adjustment and opening up trade with countries around the pacific rim, including mexico, is going to make canadian manufacturers less competitive, and lead to outsourcing and job losses. while this may technically reduce emissions in canada, the process this will spur is not a carbon transition, but one of deindustrialization - similar to the emissions reductions we saw in 2008, at the height of the last economic crisis.
this needs a border tariff to work.
and, nobody is going to care, either. nobody is going to take this ideologically pure liberal position on border taxes - well, at least, not anybody that wasn't going to oppose you, anyways.
liberals in the modern era are supposed to be pragmatic rather than ideological. this is a good example of a scenario where that pragmatism is necessary.
otherwise, this is not just incoherent, but potentially damaging.
