While that is correct, here's a real world example of my last hydro bill. In that billing cycle, I used 269 kWh.
Electricity: $22.56
Delivery: $48.92
Regulatory charges: $1.80
HST: $9.53
Ontario Energy Rebate: -$8.67
Total: $74.24
They are always advertising their low electricity rates, but in light of the delivery charge (more than twice as much), the electricity rates don't make a huge difference. YMMV. I'd be interested in seeing the detailed cost at a higher consumption as the fixed cost part of the delivery charge might play a bigger role in my case than it does in other cases.
