Agree, I also live in T.O. and my SCE bill went down about $50 but I changed the pool equipment to run during the TOU period. That won't work in the summer but for now it's additional savings.
I leave the pump for our pool on Super Off Peak. If we plan to use the pool during peak hours, I just turn it on then, and off when done swimming.
Still cheaper than moving the pump back to Peak hours in the summer
