So what did they leave in their platform?

Liberal Party of Canada
Discover the Liberal Party of Canada and the Liberal team, and what it means for you to choose forward with a positive plan for a strong middle class, a clean environment, and a growing economy that works for everyone.

This is their latest policy statement.
Of note is number 3. I’m surprised that is placed that high and may support a previous an analysis that they may be planning to quietly increase defense. I’ll believe it when I see it though.
Number 9 is an interesting one.
I also bet that UCB becomes a center of their next election platform. So committing to balanced budgets would conflict with a lot of their platform. In particular UCB, 4weeks vacation, primary healthcare, affordable housing etc.
Of course, some of this may not translate into campaign promises.
But it will keep or get NDP votes to head their way if it looks like a CPC win becomes a more solidified thing.
