Rural and remote residents already get a slightly larger rebate, and as a city dweller, I think their share should be higher for exactly the reason you state. Also, keep in mind that at night time, which will typically be the only time people end up using resistive heat while on a heat pump, electricity is cheaper. Ontario’s ultra-low off-peak option is even more extreme. It’s probably cheaper to run resistive heat at night, than running the heat pump during peak times.
