I’m saying they praised him as a hero, despite him being a Waffen-SS soldier
These are not connected thoughts. Someone who saved a cat stuck in a tree, who is also a murderer, is still a cat-saving hero. The murderous act does not invalidate the cat heroism.
which, notably, is exactly the combat service they’re praising him for, although again, not my point
There is an issue to be found in the speech because of this fact, but not related to the assertion that he is a hero. The heroism call had specific direction and it was not directed at his membership in the Waffen-SS. But since this is not your point anyway...
it doesn’t bode well foe their ability to decide on policy that will affect millions of people.
Under the Canadian democratic system, the representatives' job is to represent the people, not to make decisions for the people. This is like saying that a janitor failing to recognize a feature of the human anatomy does not bode well for his ability to perform open heart surgery. It truly doesn't bode well, but it would be quite silly to have that boding expectation in the first place.
