This is what I found from The Personal Insurance, which is my broker:
Estimated replacement cost of your house
Means the amount we estimate it would cost to replace or rebuild your house. We base this estimate on information you've given us about your house -- its size, construction, workmanship, features, and the quality of materials it's built with -- and with information from Statistics Canada indexes and industry sources. We don't consider the value of the land your house is built on when we estimate this amount.
Perhaps different company uses different terminology, and it's normally included in the quote.
