Before I get into explaining those scenarios, I think it's fair to say that it would be an extreme situation and one that we would not do lightly. We've never done it, and we've faced very significant challenges in our history and have never cancelled an election. If you go to the authorities in the act, it's an authority that's riding-by-riding appreciation, so it's not for general use.
On a riding-by-riding basis, if the conditions are such that, in my view, it is impractical to conduct the election—and it's a very specific criterion—then I may recommend to the Governor in Council that it be cancelled.
It can also be postponed by a week. That is perhaps less likely in a pandemic situation, because that is not likely to change all that much in a week. In all likelihood if that were to occur, the writ would be withdrawn and replaced within three months by a new writ.
