That's not quite right. What I was explaining was that the law changed, and when the first-generation limit on citizenship by descent was imposed on April 17, 2009, it continued to minimize the difference in treatment between children born abroad to Canadians and children adopted abroad by Canadians who access citizenship through the direct route. Those two groups are treated equally by the law in the sense that they're both impacted by the first-generation limit.
