My grandfather was born in Toronto in 1883(of English immigrants to Canada) and subsequently immigrated to the US about 1903. As far as I can tell he never became naturalized. According to what I've read , my mother who was born in the US in 1917, would be a Canadian citizen. I was born in 1952 long before the law was changed. I understand I "may" be considered a Canadian citizen...does anyone know what the determining factors are?
