Thanks for the explanation of terms. We call it a consumption meter or utility meter and only a demand meter if it records peaks rather than just recording total consumption. I see from Tesla's explanation that peak loads are a problem on some grids and I infer that most utility metering in your area include the ability to record peak demands and charge a premium for exceeding it.
Toronto is likely on the same grid as New York and Michigan and I know that area does have peak load times where brownouts occur.
Here in BC Demand meters are relatively rare except for the Electronic meters slowly replacing the mechanical types.
We mostly use them to monitor peak loading to identify excess capacity in a service or feeder.
