Having a threshold amount should mean that the two signatures are only needed on bigger ticket items. That would eliminate the problem for normal costs of photocopying, shipping things to cons for auction, etc. The distance (if not the difference in laws) and the time involved, might be a good thing - requiring better planning and communication to get big things done. The most recent admin would be the one to handle day-to-day activities.

Having a US and Canadian administrator at the same would be harder, though.
