Absolutely.
Whether we need it or not, I think it is extremely useful mainly for three reasons—not in any particular order.
The first reason is to have access to locations. There are locations like schools that will not be available on a weekday during a pandemic. No school will give us access to their premises with children in the school. That's a major consideration.
The second consideration is poll workers. We cannot recruit on a Monday and hope to recruit younger working-age Canadians in the same numbers that we can on a weekend, so the recruitment consideration is critical.
The third has to do with distancing. Providing two days allows us to spread the vote. If we vote on a Monday, there will be distancing. That distancing will take place in lineups on the streets in the rain or in the cold, so it will be safe, but certainly more unpleasant for voters who have to line up two metres apart on the sidewalk.
