New MY owner here. Ontario is moving from the current fixed billing of 12.8 cents/kWhr back to Time of Use (TOU) billing in November, but is giving the option to switch to 2-tiered billing. Houses on TOU previously will automatically go on TOU, with rates of 10.5, 15 and 21.7 cents/kWhr. However, your local utility website should have an application to switch to 2-tired billing, which is 12.6 cents for the first 1,000 kWhr (600 in summer) and 14.6 cents/kWhr for greater than 1,000 (or 600 in summer). If you elect to switch to 2-tiered, you can switch back to TOU at a later date. I looked at my last 2 invoices, and the cost under 2-tier is $3-5 cheaper, but without the worry of watching TOU. I use about 500 kWhr/month for EV charging, which I normally do overnight. Has anyone else looked at switching to 2-tiered billing?
