Read a Canadian business electricity bill

Start with the account, not the headline price

Write down the serving utility, customer class, tariff code and billing period. A retailer and a distributor may be different organisations. A rate from a household example, another province or an earlier period may be useful context, but it does not establish the charges on this account. Keep the original document privately; a public discussion or planning calculator does not need the account number or meter identifier.

Build an electricity-only subtotal

Separate electricity from gas, previous balances, deposits, late-payment charges and unrelated service items. Then identify the energy charge, any delivery components, the fixed service charge and billed demand. Record tax, credits and exceptional adjustments separately. The amount payable and the charge for this period can differ, so choose the quantity that matches the question you are answering.

Keep every unit attached to its number

A price in cents per kWh must be divided by one hundred to express dollars per kWh. A demand charge in dollars per kW is multiplied by tariff-defined billed demand, not by total kWh. Daily basic charges need the actual billing days. A block allowance needs its stated billing period and any required proration; silently treating a monthly block as a daily allowance changes the calculation.

A worked example with explicit assumptions

Consider an illustrative account using 5,000 kWh at CAD 0.10/kWh, with 40 billed kW charged at CAD 12/kW and a CAD 30 fixed charge. Energy is CAD 500, demand CAD 480 and fixed charges CAD 30: CAD 1,010 before tax. An assumed five percent tax adds CAD 50.50. The modeled total is CAD 1,060.50. These are teaching assumptions, not a Canadian market tariff or a quote.

Investigate a difference without announcing an error

First check dates, meter-read type, units and which charges were included. Then compare operating hours, weather exposure, equipment and occupancy. If the tariff depends on kVA, minimum demand, seasonal history or credits, obtain those inputs before deciding the difference is a billing mistake. Ask the utility to explain the specific charge and retain its response with the account records.

Choose a useful next step

Model the known components in the Canadian calculator, keeping the unknown ones visibly outside its scope. For a supplier discussion, compare supply and administration on equivalent terms while retaining regulated delivery. For an equipment project, inspect demand and capacity as well as energy. A clear record of the question, inputs and missing information makes a discussion with the utility or adviser more productive.

Find the applicable official publication

Open the province and territory source directory, then follow the serving utility’s business schedule. Keep its version and effective dates with the account.
