Since the first-generation limit was put in place in 2009, those born abroad in the second generation to a Canadian parent, as this committee is aware, are not automatically Canadian citizens. A Canadian parent needs to sponsor their child for immigration to Canada. Once the child becomes a permanent resident, they can obtain a grant of Canadian citizenship.
With this drafting issue with the bill, the provision is moving the application of the first-generation limit out to 2015, which means that those children born since 2009 who have been granted citizenship automatically become Canadians from birth. It's converting them from a grant of citizenship to citizenship by right.
When you obtain citizenship by right, you are impacted by the first-generation cut-off and cannot pass on citizenship to your future child born abroad. That is the impact of what this provision would do in the absence of the subamendment that's being discussed.
