It's nice to see that we no longer trust privatization as a the magic wand that solves public institution problems.
That said I think the 52% support for non-union gig work in Canada Post is indicative of the mindset that needs shifting if Canada is to change course in a way that makes most people better off long term.

Here in Ireland, the government postal service diversified and now also provides financial services to remain relevant and liquid. You can set up a current account with them, or withdraw cash through a post office if you already have an existing current account with another bank. I think An Post also allows you to buy bonds. They have also even entered mobile carrier service.
Other postal service in many parts of the world should follow the same model to remain relevant. These new additional and modernised services would be beneficial to serve remote communities not easily covered by mobile carriers, banking institutions and/or still rely on traditional mail service.
