Looking at the idea of special circumstances

Normally when one is thinking about electoral boundaries, the term special circumstances is only used to allow ridings with populations that are too low, why not do it to allow a population that is too high?

I am having trouble thinking of a place where one could do this. I was looking at the Capital Regional District and seeing what happens if you lose an MLA, but a single larger riding does not seem to be able to make up for the population over run in the rest of the ridings.

I am thinking about this because I am trying to see what tools there are to achieve better representation in rural BC.
