<prompt> Human: As noted, my mom was a Canadian citizen when she had me in the 70s. She naturalized a few months after I was born. I had always thought I missed an opportunity to get dual citizenship as it used to be I needed to request it by age 18. Now, in 2009, they allowed anyone who was born outside of Canada to a Canadian citizen to have automatic citizenship but you must request a certificate. Am I getting a good opportunity with medicine, travel, etc? Or am I going to get stuck with dual Tax bills? Anyone been here before? I still p,an on living in the US, but visiting Canada 1-2 times a year family still there.  <response>: Being a Canadian citizen will not entitle you to free health care unless you also reside in Canada. So, if you live in the US thats out.Unlike the US, Canada does not make its citizens file an income tax return if they live outside of the country and have no domestic income.About your only advantages would be easier travel to Canada, and the ability to move there if you want.
