You may be a Canadian citizen. Then again, you may not...

The WSJ reports that an amendment to Canada's Citzenship Act automatically restores nationality to many children of Canadian citizens forced to renounce it or born outside the country, and to their children's children:

Eligible individuals automatically become Canadian citizens. But they don't get proof of that citizenship unless they apply for it, meaning other countries -- including those that allow people to be citizens of only one nation -- won't be alerted, according to the immigration office spokeswoman. Those people also may renounce their citizenship rights, she said.

The citizenship bonanza is the byproduct of a decades-long struggle by a motley group of people who claim they were unfairly denied or lost their Canadian nationality. Canadian families who crossed the border in 1947 to 1977 to have their babies in a U.S. hospital found those children weren't recognized as Canadians unless the families registered them with the government. Some foreign brides of Canadian World War II servicemen lost their citizenship if they stayed out of the country for a decade or more.

Then there are the Canadian Mennonites who moved to Mexico in the 1920s to the 1960s. When their children and grandchildren returned to Canada, many found their nationality unclear.

Some such cases languished in litigation for years. Others surfaced in 2007, when new U.S. rules requiring passports for travel between Canada and the U.S. uncovered significant numbers of people who thought they were Canadian, but weren't.
