About Energy retailer
The company that you mentioned must be an electricity retailer. To decide whether it is a save for you to sign a contact or not, you have to compare only one component-electricity charge. If you search Hydro Ottawa's website on Residential rates (
https://www.hydroottawa.com/residential/index.cfm?lang=e&template_id=118), you will find the following components on your each bill:
Residential Customer Rates
Electricity Charge*
• Consumption up to 750 kWh per month $0.0500/kWh
• Consumption above the 750 kWh per month threshold
$0.0580/kWh
Delivery Charge
• Transmission
$0.0107/kWh
• Hydro Ottawa Delivery
$0.0171/kWh
• Hydro Ottawa Fixed Charge
$5.98 per month
Regulatory Charge $0.0062/kWh**
Debt Retirement Charge $0.00694/kWh***
If you sign contract with a retalier, you still have to pay the same Delivery, Regulatory and Debt Retirement charges. However, they will offer you different deal on Electricity Charge which you need to compare to.
Hope it helps.
