It certainly is explicitly only advisory, because the bill ends with the Chief Electoral Officer reporting the results to the Prime Minister, and that leaves it up to the Prime Minister.
I could imagine a situation, Mr. Reid, where perhaps the election had been contaminated in some way. I find it a little hard to imagine, but perhaps some kind of racism had been openly part of the election; the Prime Minister might decide then that this really was one case where he wasn't prepared to accept the outcome. This would, I think, be open under this bill, and I don't think it's an impossible scenario.
