First, a Mixed Member model as recommended by the Law Commission of Canada will keep local MPs from both urban and rural areas. You get both a local MP and some diverse regional MPs.
So we’re not talking about classic “list-PR” with candidates appointed by central parties.
When many people say “urban,” they mean “large urban.” Stats Can classifies “large urban population centres” as “larger than 100,000.”
So it’s not just rural areas that fear their community will lose their MP accountable to no one else. Small and medium population centres, and even ten population centres over 100,000 like Guelph and Moncton, have only one MP representing them.
We’re talking about 44% of the population of Canada.
Second, MMP will not change the urban/rural balance at all.
Fair Vote Canada's principles include “We must give rural and urban voters in every province, territory and regional community effective votes and fair representation in both government and opposition.”
The numbers of MPs from each province stay the same. Within each larger province, the number of MPs from each region stays the same (Northern Ontario will still have nine MPs north of the French River.)
Within each region, three present ridings become two larger ones, or five present ridings become three larger ones. That doesn’t change the urban/rural balance.
An urban myth: rural areas are
