The issue of the 92 years is not really a statistical issue. This is an issue for genealogists and historians. The tradition has been in Canada that after 92 years, generally speaking, public records become accessible, and that used to apply to the census.
A long time ago, the 1918 Statistics Act applied to the censuses conducted prior to it. Then the Statistics Act came along and said that all data was confidential and gave the impression that it would be in perpetuity.
The issue was raised about whether the data from Statistics Canada should be made public. There was strong lobbying by genealogists and historians that this data were important, and in making data public after the normal life expectancy shouldn't be that controversial. Proposals were adopted in the Statistics Act that asked for consent. They've been ineffective in getting people to respond to them, let alone whether they.... Some people won't respond for their children, because they want to wait until they're adults. Other people won't respond for their spouse. Other people never get to that question and stop before they get there.
Even the noes aren't necessarily noes and the result is that genealogists have lost a significant level of access. It's no longer a 100% record. They would like to see it restored.
We thought there might be an impact on Statistics Canada's operations if, in fact, we did not ask for consent. It was seen that that's not the case, so we, Statistics Canada, during my appointment when I was there, were of the view that we saw no harm in accommodating the genealogists and the historians in making the data available without bothering to ask for consent after 92 years, or any other period that Parliament might want to adopt: 108, 114, the maximum life expectancy of a Canadian.
In terms of the ability of Statistics Canada to carry out its mandate, this is not critical to Statistics Canada's operations, so it really is a decision for Parliament to decide whether they would like to continue with consent, whether they'd like to go back to the case where Statistics Canada information is no longer available ever, or whether Parliament wants to adopt the 92-year rule and automatically make the data available to the public archives after a fixed period of whatever length.
