I'd only apologize for something that I should have known given the information I had at the time.
Most mistakes are only mistakes in retrospect, but at the time seemed like good or at least reasonable ideas. I don't apologize if I've done my due diligence at the time.
And I'm Canadian, saying sorry is like our favourite pastime :)
That said, sometimes I'll convey that I wished I had seen things better in the past, and sometimes that comes out like an apology (eg:sorry folks, I wish I had known this tech was totally unsuitable here).
