Leon and PMM are incorrect in this matter. They forgot to read the rest of the Canadian Citizen Act.
Section 3 Paragraph 1 does state that a child born in Canada, is automatically a Canadian citizen but if you continue reading the act,
Section 3, paragraph 2. Specifically address children born to parent that are not citizens or permanent residents of Canada.
(2) Paragraph (1)(a) does not apply to a person if, at the time of his birth, neither of his parents was a citizen or lawfully admitted to Canada for permanent residence and either of his parents was
(a) a diplomatic or consular officer or other representative or employee in Canada of a foreign government;
(b) an employee in the service of a person referred to in paragraph (a); or
(c) an officer or employee in Canada of a specialized agency of the United Nations or an officer or employee in Canada of any other international organization to whom there are granted, by or under any Act of Parliament, diplomatic privileges and immunities certified by the Minister of Foreign Affairs to be equivalent to those granted to a person or persons referred to in paragraph (a).
@ Leon, before you start quoting a Canadian Act and giving advice to people, you should know your facts!
Maybe you should read the citizenship manual? http://www.cic.gc.ca/english/resources/manuals/cp/cp09-eng.pdf
7.2. Citizenship by birth on soil – A3(1)(a)Citizenship by birth on soil – jus soli
Citizen's date of birth: after February 14, 1977
This paragraph applies to individuals born in Canada. In most cases, a person born in Canada is automatically a Canadian citizen at birth.
Note: According to the Interpretation Act, “Canada” includes the “internal waters of Canada and the territorial sea of Canada”. “Internal waters” is further defined as "the internal waters of Canada as
determined under the Oceans Act and includes the airspace above and the bed and subsoil below those waters”. As such, children born in Canadian airspace, whether over Canadian waters or
over Canadian land, are considered born in Canada, as are children born in Canadian waters.
The interpretive clause in A2(2)(a) of the Citizenship Act is to be used only when a child is born outside of Canada. Any application based on birth in Canadian airspace or water should be
referred to OMC (nat-cit-operations @ cic.gc.ca) for consultation with Legal Sevices.7.3. Exception to birth on soil – A3(2)
A child born in Canada to an accredited foreign diplomat is not Canadian at birth unless the other
parent is a Canadian citizen or permanent resident at the time of the child's birth
3(2) of the Act).
