up here 400 amps is pretty common. We have cities that zone for "intergeneration" houses which are basically a 3-4 bedroom house with a bungalow hanging off the side. Since they dont want people buying these and using the bungalow as an income suite they wont let them be separately metered or heated. Since in quebec we are majoritarly heated with electricity a house this big on a single service needs a big entrance. One house i visited with a collegue had an electric forced air furnace heating a 4 bedroom house and a 3 bedroom bungalow attached, the furnace alone called for 150 amps. The bungalow had a 100 amp panel and the 4 bedroom a 200 amp panel. I have a feeling when it gets cold in the winter and that furnace fires up you will get a breeze from the disk on the meter!
