Had a government bill worked its way through to the Senate and not been voted on at third reading by the time prorogation occurred, then it would be off the Order Paper in both houses. So, this is quite unique and it's a unique rule to the Senate.
Si un tel projet de loi était parvenu au Sénat à l'étape de la troisième lecture, mais sans que le vote ait lieu, au moment de la prorogation, il n'aurait plus été inscrit au Feuilleton de l'une ou de l'autre Chambre.
