Not Social Security - Name Change in Canada

In Canada, it's difficult to get a sense of what women are doing. In most provinces, women can still simply assume their husbands' surnames and no one keeps track. However, in Quebec, women must retain their names when they marry. In Ontario, women may still assume their husbands' names, but if they wish that name to show up on a credit card or driver's licence, they must legally change it. Of 67,644 marriages in Ontario in 1993, 12,758 women legally adopted their spouses' names. If you look ahead to 2,000, of the 65,395 marriages, 3,535 decided to change their names.

From those statistics, it might appear that the majority of Ontario women are bucking the trend in the States and keeping their names. However, bearing in mind the Wedding Bells survey, perhaps they're simply assuming their husbands' names to the world, and not bothering to change the documents because of the time and expense.

I haven't found any statistics for the US - anyone know of people who don't do a social security name change, or passport name change, or DMV, just due to the time and expense?
