I only charge my car in off-peak hours, which is probably the case with most other EV owners in Ontario with TOU pricing. The Government of Ontario is moving to a fixed rate for electricity of $0.128/kWh - no more TOU pricing. The price over the winter for non-peak (at least in Toronto) was $0.101 - so the price we pay to charge is going up by 27% if you charge in off-peak.
The good news is that On-peak electricty will also be priced at $0.128 so you will spend less during the day when your AC is running.
I did some analysis a few years ago and my electricity consumption ranged from 72% off-peak (in the winter) to 58% off-peak (in the summer). I have a large house with two ACs, lots of electronics, a hot tub and a swimming pool so people with smaller homes may see even a higher percentage of usage in off-peak. For my historical usage from 2014-2017 using the most recent TOU pricing vs fixed rates I would pay an additional $3 per month on average. That is less than a 1% increase as my bills average over $500.
Note that these rates are all the variable rate - there are various other surcharges and fees that increase your total fee for electricity.
