I can confirm I was able to travel with my first passport, the one associated with my initial citizenship, and the original eTA, without having to reapply to declare getting an additional citizenship.
Like with many other similar questions the answer is an unequivocal no. As long as you’ve been completely truthful at the time of the application, there’s never an obligation to inform the immigration authorities about material changes in your citizenships, jobs, marital status, residence address, and a myriad of other factors that may change between the time you apply for a visa and the time you travel to the country in question. Of course, Canadian immigration officers are free to ask you whatever additional questions they see fit at the border and that’s where you might have to disclose your second passport. But as far as the original ETA application goes you’re 100% in the clear.
Enjoy your stay in Canada.
