I'm not sure Percy. My son grew up in Canada and married an American and moved south of the border. When he took up US citizenship he had to renounce his Canadian citizenship. However he did that in the US so it probably wouldn't make any difference if he wanted to come back to Canada,
One of his sons was looking at working in Canada but it seemed that there was an age cut-off around 19. However, as you have never lived in Canada I would doubt that you are a citizen but you could possibly apply for citizenship although I would think that you would have to show that you intended to move up here.
Someone mentioned taxes and Canada, unlike the US, does not tax Canadians that are resident and earning in another country. My wife is dual having grown up not far from you in Boston and the IRS is a nightmare to deal with. She hasn't lived in the US for nearly 38 years and yet every year we have to not only fill out a US tax form but also the FBar form and now it looks like they have added another one. I have never been able to get a straight answer to any inquiry from the IRS.
He has told you, O man, what is good ; And what does the LORD require of you But to do justice, to love kindness, And to walk humbly with your God.
