The secret ballot happens under two circumstances, if I'm not mistaken. I'm looking to the Clerk for confirmation. Yes. One is, of course, for the election of the Speaker, and the other one is for private members' business.
I'll hand it over to Mr. Gagnon, who will be able to answer that much better than I will, because it happens so rarely. It's only happened once to me while I've been here, since 2004, with a slight interruption in 2011.
Mr. Gagnon.
