"Starting today, any individual will have to show his or her face when taking the oath of citizenship. Recently I received complaints from members of the Parliament, citizenship judges and even participants in citizenship ceremonies to the effect that it is difficult to ensure that the individuals whose faces are covered are really taking the oath," Kenny said.
"But this is not a simple or technical measure, far from it, this is really a matter of pure principle which is at the very heart of our identity and our values with respect ti openness and equality," Kenny said. "The oath of citizenship is basically a public gesture, a public declaration that shows that you are joining the Canadian family and this has to be done freely and openly, not secretly. Isolating and separating a group of Canadians or allowing that group to hide their faces while they are becoming members of our community is completely counter to Canada's commitment to openness and social cohesion."
"The new rule requires the citizenship judge to see the person's face as the oath is being spoken. Once the oath is completed and the national anthem sung, the individual can cover her face and begin a new life in Canada as a citizen,"
