According to Kinsella, Shifty was an okay guy deep down. If only we had been as privileged to know him as WK did, we'd see him much differently and so it's "farewell, good luck and God speed."
For a slightly different take there's Michael Harris' eulogy, "Goodbye Harper, Good Riddance. How do you sum up the career of a guy who betrayed every ideal he claimed to cherish?"
In this passage, Harris lays bare our once prime ministerial malevolence:
Stephen Harper was Donald Trump before Trump was Trump, right down to the bigotry, fear-mongering, divisiveness, scapegoating, and profound anti-democratic impulses that had Canada’s entire parliamentary structure tottering, according to experts like Peter Milliken and Robert Marleau.
While others will remember amusing episodes involving personal encounters with Harper, I will remember the look on the face of Canada’s former nuclear safety commissioner, Linda Keen, while she recounted her personal destruction at the hands of his government because she wouldn’t sell out her mandate.
It was the same look I saw in Richard Colvin’s eyes when the former diplomat was smeared by Harper and Peter MacKay for the high crime of telling what he knew about the as-yet-unresolved Afghan detainee affair.
WK may fawn over the guy but Harper was a mean-spirited, brutal prick as a prime minister and, as Harris notes, the country is well rid of him. Even the dregs of the Conservatives who carry on admit as much.
