Lee, in Ireland a citizen changes name via a deed poll. A non-citizen requires a license to do so. This license is provided by the Aliens Act of 1935. As far as I'm aware that's the act that needs to be substituted for ONTARIO CHANGE OF NAME ACT.
This Notice was originally posted as a notice to be given in lieu of identification...
