With the release of Provincial Economic Accounts on November 7, 2002, we will be implementing the chained Fisher formula of calculating real GDP.
For trade data, we will be aggregating the 679 commodities to 57 commodity groups. These are the Input/Output (IO) defined 57 commodity groups. This does not alter the quality of the total trade estimate as the chained-Fisher estimates based on 679 commodities and those based on 57 commodity groups were shown to be similar.
The Income and Expenditure Accounts (IEA) include quarterly estimates of Canada's international trade broken down to trade in goods and trade in services, as defined on a Balance of Payments (BOP) basis. IEAD also publishes annual estimates of each province's international trade, with the provincial distribution of the trade commodities originating from the detailed commodity Input/Output system.
The total trade estimate obtained by summing the provinces equals the national published total trade on a BOP basis, however, the total goods and the total services do not sum to the national totals. This is due to the different classifications of goods and services between the BOP and the IO systems.
The following details why we will no longer publish the breakdown of goods and services; and for many of the same reasons we will no longer publish the breakdown of goods and services for inter-provincial trade data:
