I don't know that Canvas supports SAML logout.

And those are definitely insufficient changes to make logout work, if you mean full on SAML logout. The changes required are documented in the wiki, and include turning on HTML local storage via that property, and setting idp.session.secondaryServiceIndex = true

But it depends what kind of logout we're talking about.

Potentially, yes.
