I'm at page 94 of the bill, subsection 281.6(1), “Every person present at a polling station or at the counting of the votes shall maintain the secrecy of the vote.”
I would posit that this secrecy obligation lasts a lifetime. Of course that's not to the extent that official results have been made public. However, if an elector were able to be identified during the count of the votes, of course the person noticing that would be bound to secrecy for an extended period.
