On March 7, 2017, the Senate Standing Committee on Social Affairs, Science and Technology presented its report on Bill C-6, without amendments but with comments. The Bill is now back in Chamber for a third and final reading. Several changes have been proposed by Senator McCoy. They essentially concern the provisions of the Bill about revocation of citizenship. Of particular interest, no amendment to the provisions regarding the total and annual presence in Canada has been proposed.
