Electricity is deregulated in two Canadian provinces: Ontario and Alberta. Both markets showed price spikes in the first year of dereguation, but then settled down into a volatile but reasonably stable environment. Alberta's market is dominated by fossil fuel generation and as such reacts more closely to the price of natural gas. Ontario's generation mix is about 50% nuclear.
Switching electricity supplier could shave pounds off your bills. But it’s not always about how much hard cash you could save. You might be fed up with poor customer service, you might want greater visibility of your usage through an app or you might want to choose your supplier based on their green credentials, or whether they supply a smart meter.
