Canadian International Merchandise Trade (Balance of Payments Basis)
This activity consists of adjusting the values of Canada's imports and exports from the Customs basis to the Balance of Payments basis.
Detailed information for May 2015
Data release - July 7, 2015
This activity consists of adjusting the value of Canada's imports and exports from the Customs basis to the Balance of Payments basis. Information on imports and exports are inputs into the Canadian System of National Accounts, particularly in the Balance of Payments and Gross Domestic Product, and are used in the formulation of trade and budgetary policies. Governments, importers, exporters, manufacturers and shipping companies use trade statistics to monitor import penetration and export performance, monitor commodity price and volume changes and examine transport implications.
Canadian International Merchandise Trade (Customs basis) is the main source of data for trade in goods for the Balance of Payments basis. However, there are conceptual differences concerning the coverage, time of recording, valuation and classification of goods transactions between Customs and Balance of Payments that require adjustments to Customs data for use in the Balance of Payments.
Key differences exist between Customs and BOP based data. On a BOP basis, transactions are defined in terms of ownership change between residents and non-residents (i.e., BOP trade can sometimes occur completely within or outside of Canada). On a Customs basis, a transaction occurs when a good crosses the border. Other major differences involve the country of attribution for imports (BOP is country of shipment; Customs is country of origin) and valuation (most notably: freight for BOP purposes is moved out of merchandise trade and into transportation services).
BOP adjustments to Customs data are frequently carried out at aggregate levels (both for commodity and country groupings), making the direct relationship of detailed Customs data to the BOP data difficult where possible at all. BOP data are available for commodity groups and their aggregates at the national level and at the "all commodity" level for Canada's Principal Trading Partners (Algeria, Australia, Belgium, Brazil, China, European Union, France, Germany, Hong Kong, India, Indonesia, Iraq, Italy, Japan, Mexico, Netherlands, Norway, Peru, Russian Federation, Saudi Arabia, Singapore, South Korea, Spain, Switzerland, Taiwan, Turkey, United Kingdom, United States).
This activity is part of the Canadian International Merchandise Trade Statistical Program. The primary objective of this statistical program is to measure the change in the stock of material resources of Canada resulting from the movement of merchandise into or out of the country.
Canadian trade statistics are compiled according to the "General" system of trade as defined by the United Nations Statistical Office. The general trade system is in use when the statistical territory of a country coincides with its economic territory. Consequently, under the general trade system, imports include all goods entering the economic territory of a compiling country, and exports include all goods leaving the economic territory of a compiling country.
The closing of the statistical month for imports and exports is defined as the last calendar day of the month based on the date of clearance from Customs. Documents received too late for incorporation in the current month are assigned to the month the transaction took place and are published the following statistical month.

Data sources and methodology
Imports and exports of merchandise into and out of Canada.
The administrative data collected in this program is a census. Data are collected for all units of the target population, therefore no sampling is done.
Data are collected from other Statistics Canada surveys and/or other sources.
Data on Canadian merchandise trade are obtained on a Customs basis from the Canadian International Merchandise Trade (Customs Basis) - Statistical Program # 2201.
Additional inputs are sourced from other Statistics Canada programs.
The Customs basis data are aggregated by commodity and Principal Trading Partner, and pertinent adjustments are made to convert them to the Balance of Payments basis.
Overall, the adjustments on exports are more numerous and sizeable than on imports.
Aggregated data are subject to month over month and year over year analysis to detect errors and explain observed movements.
The models used to seasonally adjust are reviewed annually by the Business Survey Methods Division of Statistics Canada.
Statistics Canada is prohibited by law from releasing any information it collects which could identify any person, business, or organization, unless consent has been given by the respondent or as permitted by the Statistics Act. Various confidentiality rules are applied to all data that are released or published to prevent the publication or disclosure of any information deemed confidential. If necessary, data are suppressed to prevent direct or residual disclosure of identifiable data.
The Canadian International Merchandise Trade Statistical Program (CIMTSP) of Statistics Canada is similar to most other countries in its use of administrative data derived from Customs sources to produce merchandise trade data and its use of the 'passive suppression' approach for confidentiality. Passive suppression is based on the principle that confidential data will not knowingly be released. It requires that appropriate measures be taken only at the request of importers or exporters who feel that their interests would be harmed by the dissemination of data. The onus of notifying CIMTSP of suspected instances of the release of confidential data rests with the affected companies.
Revisions and seasonal adjustment
Merchandise trade data are revised on an ongoing basis for each month of the current year. Current year revisions are reflected in both the Customs and BOP based data. The previous year's Customs data are revised with the release of the January and February reference months as well as on a quarterly basis. The previous two years of Customs based data are revised annually and are released in February with the December reference month. The previous year's BOP based data are revised with the release of the January, February, March and April reference months. Revisions to BOP based data for previous years are released annually in December with the October reference month.
Factors influencing revisions include late receipt of import and export documentation, incorrect information on Customs forms, replacement of estimates produced for the energy section with actual figures, changes in classification of merchandise based on more current information, and changes to seasonal adjustment factors.
Revised data are available in the appropriate CANSIM tables.
The administrative data used to compile trade statistics is considered to be complete and accurate. Any anomalies or inconsistencies detected are verified with the source, and where necessary, adjustments are made to reconcile data with the conceptual framework of the series. The administrative agencies used are considered to be the best source available.
It is not unusual for the accuracy of export statistics to be adversely affected by undercoverage and/or country misallocation. While Statistics Canada does not have a direct measure of undercoverage, a monthly estimated adjustment is included within BOP based data. Country misallocation occurs when the country of final destination is inaccurately reported on the Customs documentation. This occurs most frequently when goods are routed through an intermediary country before continuing to their final destination with the intermediary country being reported as the final destination of the goods.
