I'll give you my answer, which is yes. The basis for it is my sense of members and constituencies, which is the same issue we have in the northern parts of Canada where the constituencies are very small in numbers but huge in size. It's also true in the northern parts of the provinces. I think we're entirely justified in having fewer constituents per member in the north.
When we get to the south, I have not yet seen a really good study of constituency work by MPs. I've done some work myself, and I am satisfied that the big-city MPs—and it very much depends on riding—have enormous workloads, and some don't.
