3. Energy Consumption, by Energy Source

Table 4 presents the amount of energy consumed by commercial and institutional establishments in Canada in 2005 for each energy source, by region.

Natural gas accounts for the greatest portion of energy consumed, with 44 percent of all the energy consumed in Canada, while electricity represents 42 percent (as shown in Chart 4 on page 13). At the other end of the range, steam power represents 5 percent of energy consumed, followed by heating oil and other middle distillates at 3 percent.

From a regional standpoint, electricity represents a significant portion of total energy consumption in Eastern Canada, accounting for 61 percent in Quebec and 44 percent in the Atlantic region. Natural gas dominates in all other regions, accounting for 54 percent in Ontario, 53 percent in the Prairies and 43 percent in British Columbia.

The letter to the right of each estimate indicates its quality, as follows: A – Very good, B – Acceptable, C – Use with caution, F – Too unreliable to be published or eliminated for reasons of confidentiality.

¹ The residual category Other includes wood and wood residues and, to a limited extent, coal, solar panels that use solar energy to heat fluids and all other forms of energy used.

Due to rounding, the numbers may not add up to the total shown, and some numbers may differ slightly from one table to the next.

Heating oil and other middle distillates are used mainly in the Atlantic region, where they represent 23 percent of total energy consumption, but also in Quebec, where they account for 6 percent of energy consumed. Heavy fuel oil consumption remains low in Canada; only 1 percent of all commercial and institutional establishments use it. The Atlantic and Quebec regions consume 80 percent of the heavy fuel oil used in Canada, with universities and hospitals being the primary consumers.
