General information
Purpose of survey
The purpose of this survey is to obtain information on the supply of, and demand for, energy in Canada. This information serves as an important indicator of Canadian economic performance, and is used by all levels of government in establishing informed policies in the energy area. In the case of public utilities, it is used by governmental agencies to fulfill their regulatory responsibilities. The private sector also uses this information in the corporate decision-making process. Your information may also be used by Statistics Canada for other statistical and research purposes.
Data-sharing agreements
To reduce respondent burden, Statistics Canada has entered into data-sharing agreements with provincial and territorial statistical agencies and other government organizations, which have agreed to keep the data confidential and use them only for statistical purposes. Statistics Canada will only share data from this survey with those organizations that have demonstrated a requirement to use the data.
Section 11 of the Statistics Act provides for the sharing of information with provincial and territorial statistical agencies that meet certain conditions. These agencies must have the legislative authority to collect the same information, on a mandatory basis, and the legislation must provide substantially the same provisions for confidentiality and penalties for disclosure of confidential information as the Statistics Act. Because these agencies have the legal authority to compel businesses to provide the same information, consent is not requested and businesses may not object to the sharing of the data.
For this survey, there are Section 11 agreements with the provincial and territorial statistical agencies of Newfoundland and Labrador, Nova Scotia, New Brunswick, Quebec, Ontario, Manitoba, Saskatchewan, Alberta, British Columbia, and the Yukon.
The shared data will be limited to business establishments located within the jurisdiction of the respective province or territory.
Section 12 of the Statistics Act provides for the sharing of information with federal, provincial or territorial government organizations. Under Section 12, you may refuse to share your information with any of these organizations by writing a letter of objection to the Chief Statistician and returning it with the completed questionnaire. Please specify the organizations with which you do not want to share your data.
For this survey, there are Section 12 agreements with the statistical agencies of Prince Edward Island, Northwest Territories and Nunavut.
For agreements with provincial and territorial government organizations, the shared data will be limited to business establishments located within the jurisdiction of the respective province or territory.
Record linkages
To enhance the data from this survey and to minimize the reporting burden, Statistics Canada may combine it with information from other surveys or from administrative sources.

Reporting Instructions and Natural Gas Definitions
Question 1: OPENING INVENTORY
1a: Opening inventory of base or cushion gas
Report total amount of base or cushion gas held by the establishment on the first day of the month under review. This should equal the closing inventory of the previous month.
Definition:
- Base gas, also referred to as cushion gas is the amount of gas that must be present in storage at all times to maintain a storage facility’s pressure.
1b: Opening inventory of working gas
Report total amount of working gas held by the establishment on the first day of the month under review. This should equal the closing inventory of the previous month.
Definition:
- Working gas is the amount of gas that can be withdrawn from storage while maintaining a storage facility’s minimum operating pressure.
Total opening inventory of natural gas
Report total amount of natural gas held by the establishment on the first day of the month under review. This should equal the sum of the base/cushion gas and working gas.
Question 2: CLOSING INVENTORY
2a: Closing inventory of base or cushion gas
Report total amount of base or cushion gas held by the establishment on the last day of the month under review.
Definition:
- Base gas, also referred to as cushion gas is the amount of gas that must be present in storage at all times to maintain a storage facility’s pressure.
2b: Closing inventory of working gas
Report total amount of working gas held by the establishment on the last day of the month under review.
Definition:
- Working gas is the amount of gas that can be withdrawn from storage while maintaining a storage facility’s minimum operating pressure.
Total closing inventory of natural gas
Report total amount of natural gas held by the establishment on the last day of the month under review. This should equal the sum of the base/cushion gas and working gas.
Question 3: HEATING VALUE OF STORED NATURAL GAS
3: Average heating value of stored natural gas in gigajoules per thousand cubic metres
Report average heat content of your natural gas held in storage for the month under review.
Question 4: INJECTED, WITHDRAWN AND INVENTORY ADJUSTMENTS OF NATURAL GAS STORAGE
4a: Injected in to storage
Report total amount of natural gas received by the establishment for month under review.
4b: Withdrawn from storage
Report total amount of natural gas delivered by the establishment for month under review.
4c: Other adjustments
This calculated amount is the difference between (1) opening and closing inventories and (2) injections and withdrawals. This difference includes discrepancies due to meter inaccuracies and/or leakage or other losses. Inventory adjustments can be a positive or negative value.
- Inventory adjustments = (closing – opening inventories) – (withdrawals – injections)
Net withdrawals of natural gas from inventories
This calculated amount is the difference between (1) withdrawals and (2) the sum of injections and inventory adjustments. Net withdrawals can be a positive or negative value.
- Net withdrawals = withdrawals – (injections + inventory adjustments)
Question 5: NATURAL GAS HELD IN THE UNITED STATES
5: Natural gas in storage facilities in the United States
Report total amount of natural gas held by the establishment in storage facilities located in the United States for eventual use in Canada.
