I was quite specific in mentioning westernized/industrialized countries, and countries that are quite large.
Haiti -Haiti isn't bilingual their creole is a creole of french. It's not a country split between languages, it's a country where people pick and choose what language they want to speak at a given time, as their culture is creole and their world is french.
Paraguay-Similar but totally different it's properly bilingual and is a country focused on a dual spanish-amerindian heritage.
Afghanistan
India
Israel
Kyrgyzstan
Pakistan
Sri Lanka
Timor Lestel
None of these are politically stable in the long term, not a list of countries canada want's to be part of.
Philippines- Hard to predict, held together by a strong sense of nationalism, largely based on a christian heritage, frequently getting tangled in with muslims/indonesians. FYI, each island has more or less it's own language/dialect. In that sense yes the two countries are very similar. People have suggested before Canada is like an archipelago of island nations, it's closer to the truth. If you look at a population map with no geographic features you'd never guess it's a singular landless.
Singapore- It's a city demographically comparable to Toronto ironically. It isn't remotely like Canada but it might give us a hint in what Toronto could be like in 30 years. A quadlingual defacto pseudo state(where french isn't spoken).
Belgium-comes up all the time, turns out the country is a postage stamp in size, there's no reason to be together but no reason to part either.
Belarus- Not politically stable, totally totally uncertain if it's a country that'll exist in a few months forget years.
Finland- Only on paper the Swedish speakers are a small minority.
Ireland- No one speaks Gaeilge
Bosnia and Herzegovina
Kosovo
When they phrase balkanization is used about a country, best not to use Baulkan countries as proof the country isn't gonna balkanize.
Luxembourg- Not really a country quite literally, it's closer to a multi lingual suburb. Point is you don't split a tiny city in half.
Malte-I'll be honest this is literally the only one on the list I don't know much about.
Norway- You mind want to use google on that one. It's absolutely not bilingual.
Swiss- That's a tangly mess.
Not touching African nations.
To the point which if any of these countries above will exist in 300 years? Finland being
