Depends on how your country deals with it, like if you want to apply for a new passport.
Doesn't seem likely that Canada automatically shares the information, but the other country could request this knowing that you've resided in Canada.
If your country doesn’t allow dual citizenship then I wouldn’t take such chances. Need just one officer to find out and it is a crime and you could face fines

I am fortunate that my country of origin allows dual citizenship, but I can imagine how difficult it is to give up your country of origin's citizenship for some people, as you no longer have the option to return to your country as many and as long as you want to visit your parents and siblings ... etc without conditions or limitations, and who knows things may not work out in Canada in the long-term as you have wished, and then you are stuck.
Technically, I could simply apply to become a Dutch citizen again. Since my spouse is a Dutch citizen, I won't have to give up my Canadian citizenship.
Yeah, so while Canada doesn’t transmit citizenship info, it’s the other countries that do have safeguards (like the one year residence you mentioned) when they restrict or discourage dual citizenship. It does sound like you qualify to keep both nationalities under certain conditions since your spouse is a Dutch citizen.
My country of origin allows dual citizenship as well, but…nah. No thank you lol.
I think the answer to anyone having such doubts then is to stay as a PR in Canada. There is really nothing major you're missing out being a PR (you have all the key benefits) plus you can retain your birth country's citizenship as well.
Yep - you can always reapply and go through the process again. But if anyone has a ton of doubts about giving up their birth country's citizenship, then continue staying as PR. I know people who've stayed on as PR for 30 years in Canada.
