Although Canada restricted dual citizenship between 1947 and 1977, there were some situations where Canadians could nevertheless legally possess another citizenship. For example, migrants becoming Canadian citizens were not asked to formally prove that they had ceased to hold the nationality of their former country. Similarly children born in Canada to non-Canadian parents were not under any obligation to renounce a foreign citizenship they had acquired by descent. Holding a foreign passport did not in itself cause loss of Canadian citizenship. Wikipedia

Your parents had to choose for you in 1970, to be a Canadian or a U. S. Citizen at time of birth.

Maybe you can figure this out for yourself, since Ted had to renounce his Canadian citizenship in 2014.

Is that “born in Canada” for non-citizen parents traveling in Canada, or to parents who have settled in Canada? Teds father had applied for Canadian citizenship, and was a Can citizen before they moved to TX. To my knowledge Teds mother has never gone on record one way or the other about whether she had applied or been granted Can citizenship.
