The answer lies in the last sentence. It should say the same thing in English. It reads:
The Chief Electoral Officer proposes an amendment to section 20 of the Canada Elections Act by dividing it into two parts: one part for those temporary employees directly involved in the preparation for and the conduct of elections [...]
So it would be those who are involved in the intensive preparation for elections. So we are really talking about the preparation.
I do not fully agree with Mr. Proulx when he says that elections are being prepared--he forgets minority governments--over four years. Of course he does some work, but it is mainly during the fourth year of a Parliament that he starts to ask his returning officers to do an inventory of locals. The second part of section 20 would apply to other temporary employees he would need to carry out his duties.
You may ask for additional information but we, in the Bloc Québécois, support the proposal.
