Thank you, first, for the question. It's a very practical question and an important one.
I would initially look at geography over population, although they both have to be factored in and a balance has to be struck.
For example, in the city where I am right now in Hong Kong, as I mentioned, there are almost 400,000 Canadians living here. If ridings were based purely on population relative to other regions in the world, there might be a disproportionate number of seats coming from here, and that would create advantages and disadvantages, depending on a person's perspective.
I think, initially at least, that would be better looked at if that were not the case—if it were divided up geographically, not necessarily with an equal number of population per riding but through an approach established collaboratively through various sets of stakeholders—committees like this one, for example, or one like it—so that there is geographic representation.
The idea of Canadians abroad conjures ideas that we're talking about the entire planet, and there needs to be representation within a range of populations across a relatively equal number of regions across the planet.
