The available data on interstate claims including those made by Canadians residing in USA for 1992, 1993 and 1994 revealed the following:
Revenue Canada requires 25 per cent of the benefit amount be retained at source for income tax. The total number of claims represents the actual number of claims received but not the number of claimants who actually were eligible for benefits. This information is not readily available. We have no available data to distinguish if the recipients are non-Canadians, or their state(s) of residence.
Revenue Canada taxation does not require that employers report premiums per individual social insurance number. Therefore we cannot specify how much was collected from these recipients. We do not have statistics on the claim types such as maternity, parental or sickness benefits.
Historically the volume of such claims has been too minimal to warrant the design of computer programming to keep such detailed information as requested.
