I have just one comment about the irritant of having candidates outside of a church building.
The EFC publishes an election readiness kit that stipulates that the only activities that are permitted in a church legally, or from Revenue Canada's point of view, is an all-candidates debate, where every single candidate shows up for a comment forum together, not on separate days of the week. They all have to be together. It has to be a forum in which all of them can participate in agreed-upon formats.
