Canada–United States Federal Comparisons
This section compares the financial situation of the Canadian federal government with that of the U.S. federal government.
In making such comparisons, it is important to note that there are fundamental differences in the accounting practices and responsibilities of the Canadian and U.S. federal governments.
For example, in the U.S. the Social Security system, which is the equivalent of the Canada Pension Plan (CPP) and Quebec Pension Plan (QPP), is considered part of the federal sector, whereas in Canada the CPP and QPP are not part of the federal government sector. As a result, U.S. federal financial balance and market debt figures reflect the substantial surpluses in the Social Security system, whereas such surpluses are not included in Canadian federal figures.
However, a reasonable comparison of the two countries’ fiscal situations can be made using the financial requirements/source of the Canadian federal government (rather than the budgetary balance) and the U.S. federal unified budget balance. This primarily compares the financial situation in both countries on a cash basis of accounting.
On this basis, the Canadian federal government posted a surplus of 0.4 per cent of GDP in 2001–02. By contrast, the U.S. federal government moved into a deficit position in 2001–02, recording a deficit of 1.5 per cent of GDP. In 2002–03 the Canadian federal government is forecast to have a slight surplus, while the U.S. federal deficit is expected to increase to 2.8 per cent of GDP.
Similarly, Canadian federal market debt (rather than federal debt or the accumulated deficit) is the most appropriate measure of debt to be compared with U.S. federal debt held by the public. As a result of continued surpluses at the federal level in Canada and the recent deterioration in U.S. federal finances, the difference between the federal market debt-to-GDP ratios in Canada and the U.S. has been nearly halved since 1999–2000, to 6.2 percentage points in 2001–02. In 2002–03 Canadian federal market debt is expected to decline to 38.8 per cent of GDP, while U.S. federal debt held by the public is forecast to rise to 36.1 per cent of GDP, further narrowing the gap to 2.7 percentage points.
