Across the country, there's a pretty broad spectrum of cases. Some houses already have 200-amp service. In some cases, 200-amp service is roughed in to the electrical meter, and it's simply a matter of replacing the panel. In some cases, the house is 500 metres from the road, and it would require 500 metres of new electrical line to be trenched in, which could be in the tens of thousands of dollars. It varies, based on the case.
