Density Reviews
& Rate Classes

Learn more about our rate classes and why we periodically conduct density reviews for our customers.

 

Density Reviews

We periodically conduct density reviews using a Geographic Information System (GIS) tool to identify clusters of customers who may require a rate reclassification as well as verifying that customers are properly classified according to density.

If you’re affected by a density review, we’ll send a letter with information on your new rate class as well as the associated bill impacts.
 

What is my rate class?

To determine your rate class, please check page two on your bill. Below is an example of a residential customer with a medium density.

Residential Rate Classes

(excluding Norfolk, Haldimand, Woodstock, Orillia and Peterborough service areas)

These classifications apply to year-round and seasonal residential properties.
 

Residential customers

A year-round residential property located in our service area is considered to be customer's principal residence and may include additional buildings served through the same meter, provided they aren't rental income units.

Residential seasonal customers

The residential seasonal service includes residential customers that don't meet year-round rate status. It includes dwellings such as cottages, chalets and camps. To qualify as a year-round residential customer:

  1. You must live in this residence for at least four days of the week for eight months of the year and you must not reside anywhere else for more than three days a week during eight months of the year.

  2. The address of this residence must appear on your supporting documents such as your driver's licence, credit card invoices, property tax bill, etc.

  3. If you're eligible to vote in provincial or federal elections, you must be enumerated at the address of this residence.

  4. In addition, you must represent and warrant that for as long as you have year-round residential rate status for this residence you won't designate another property that you own as a year-round residence for the purpose of our rate classification.


To help us determine whether you qualify as a year-round residential customer, we require you to complete and submit the Declaration to Apply for Year-Round Rate Status Form.

How are rate classes assigned?

We base delivery rates for each rate class on the cost of delivering electricity to that type of customer and meeting their electricity supply needs.
