I'd be happy to come back and give this some more thought. I was not prepared to speak to this subject today.
Certainly, if you increase the population, you need to increase the number of polling divisions so that there's not an inordinate number of people in each poll and they'll be better served. There may be requirements to increase the number of staff, not at headquarters as much as in the field, to support that increased balance and so forth. We'd want to look at that carefully before providing a definite answer.
Processing any significant increase in the voter population requires additional work and resources.
