section 3 of the Charter, and was rendered of no force or effect. The federal National Register of Electors is updated to reflect various changes in the Canadian population, including address changes, reaching voting age, naturalization, and death. Every year, about 3,000,000 address changes are processed by Elections Canada from information obtained from the Canada Revenue Agency, Canada Post (via the National Change of Address service), provincial and territorial motor vehicle registrars, and provincial electoral agencies with permanent voters lists. Every year, about 400,000 Canadians reach voting age and 200,000 Canadians die, resulting in changes to the National Register of Electors based on information obtained from the Canada Revenue Agency, provincial and territorial motor vehicle registrars, and provincial electoral agencies with permanent voters lists. Additionally, over 150,000 individuals a year become naturalized Canadians, and are added to the National Register of Electors by Elections Canada based on information obtained from Citizenship and Immigration Canada. Canadian citizens abroad Section Three of the Canadian Charter of Rights and Freedoms provides that "every citizen of Canada has the right to vote", including those residing abroad, although the voting age is set by legislation at 18 years of age. From 1993 to 2019, in practice only those citizens 18 years of age or older who reside in Canada or have been abroad for fewer than five years could vote in federal elections. Exemptions to the five-year limit existed for members of the Canadian Armed Forces, employees of the federal or a provincial government stationed abroad, employees of certain international organizations, and their cohabitants. The five-year limit was originally enacted as part of Bill C-114, An Act to Amend the Canada Elections Act, in 1993; these amendments extended the special ballot to certain prisoners, and Canadians "living or travelling" abroad. In September 2005, Jean-Pierre Kingsley, then the Chief Electoral Officer of Canada for 15 years, explicitly recommended in his official report that Parliament remove the five-year limit by amendment, but no action was taken. In May 2014, a court decision from the Ontario Superior Court of Justice invalidated the five-year limit as an unconstitutional restriction on the right to vote, in violation of Section Three, leading to a period of fourteen months during which all Canadian expatriates could apply to be on the register of electors. However, the decision was reversed 2-1 on appeal at the Court of Appeal for Ontario on July 20, 2015,
