What criteria guide the commissions when establishing the federal electoral boundaries?
In establishing electoral boundaries, each commission shall proceed on the basis that the population of each electoral district shall, as close as reasonably possible, correspond to the electoral quotient for the province. Commissions will consider the community of interest or community of identity in, or the historical pattern of an electoral district. A manageable geographic size for districts in sparsely populated, rural or northern regions of a province is also taken into consideration. Except in circumstances viewed by the commission as being extraordinary, the population of each electoral district in a province will remain within plus or minus 25 percent of the electoral quotient for that province.
