As much as I try and keep up with these things, I totally missed this....
Electricity Prices | OEB
They are optimizing cash flow not only based on Time of Day, but also Time of Year !
I'll leave it at, to stay within forum rules.

Your OEB time-of-use prices are all below our fixed rates. Off-peak @ 7.2 cents is more than 50% less.
A 4500 watt storage-type electric heater (those based on heating up a masonry mass) run for 10 hours overnight would cost 4.5 x 10 x $0.072 = $3.24 per day. Or about $98 per month. 4500 watts would be similar load-wise to an electric water heater.
I've never tried one of those heaters. Here is an example of 1,320 watt to 10,800 watt residential units.
Room Units Overview
Their Sizing page shows a 4-6 watt per sqft/hour heat loss for typical construction.
A room 12' x 24' = 288 sqft x 6 watts per hour = 1728 watts/hour.
A 2500 watt storage-type electric heater run for 10 hours overnight would cost 2.5 x 10 x $0.072 = $1.80 per day. Or about $55 per month.
I'm not sure how that stacks up to other heating options. Probably on the expensive side to do a whole house, but could be a reasonable solution to make one room comfortable as an auxiliary.
