That's not an opinion, that's a fact, in both raw terms and relative terms. What do I mean in raw terms and relative terms?
In raw terms, there are 195 countries in the world.
Canada ranks 17th in the Human Development Index.
Canada ranks 10th in GDP (nominal), and 16th (PPP).
Canada ranks 14th in the Index of Economic Freedom.
Canada ranks 15th in the World Freedom of the Press Index.
Canada ranks 11th in the Global Peace Index.
Canada ranks anywhere from 6th to 19th in Life Expectancy (depending on which organization you ask).
Canada ranks 15th in World Happiness.
Canada ranks 18th in Gender Equality.
Canada ranks 2nd in Credit Rating.
Canada ranks 1st in Freedom of the World which measures civil liberties and political rights.
Canada ranks 13th in the Economist Democracy Index.
Canada ranks 13th in the Legatum Prosperity Index.
Canada ranks 13th in the Human Freedom Index.
Canada ranks 7th in the Global Food Security Index.
Canada ranks 111th in the Pollution index (a the higher the number the better, it's ranking the worst countries, so 1st is the dirtiest country)
Canada ranks 8th in the production of scientific research.
Canada ranks 15th in the Global Innovation Index.
Canada ranks in the top 15 (often in the top 5) in just about every category of "5-year survivability rate" for common cancers.
Canada is the 2nd most educated country in the world.
And, if you want to accept a more subjective assessment, Canada is regularly in the top 3 best countries in the world, even during the years of the dystopian rule of the tyrant Justin Trudeau.
Further, a lot of these rankings also include some very tiny countries (in both physical size and population, i.e. Lichtenstein), and sometimes even special administrative areas (like Hong Kong). If you remove those, our rankings go up.
Finally, if you look at the countries on either side of us in these rankings, they are all countries that just about anyone would agree are "good countries".
I'm not wearing rose coloured glasses. This is a great country.
Now, what do I mean by relative terms?
@QV claimed Canada was a shithole country. Even if you aren't happy with the ranking above, they nonetheless put us light years ahead of any country someone would ever consider "shithole".
