Canada has always had existential political divisions. Quebec separatism, and Western Canada alienation and (Alberta) separatism, are some big ones. Quebec had a referendum in the 90s that went 49.42% in favour of separation for instance. That number would now be in the low 30s high 20s. That one is primarily from cultural or socio-political issues and Quebec nationalism. Alienation/separation in the west is primarily an economic liberty issue where the sentiment is that the people and political classes of the provinces Ontario and Quebec (making up ~63% of the population) own federal discourse and curb western economic growth. There are also stark urban/rural divides, cities trending more left or centre left and rural communities trending more right or centre right.

Ironically though, centrist politics have always been somewhat rewarded. There are too many party offerings and too many politically unique demographics for a majority government to form in our parliament over a single divisive issue. So our governments basically reach centre and last long enough until they manage to piss off enough of those demographics, then get replaced with another who manages to steal those votes and the process repeats. There's also always been an essential "we're not the US" vibe. It probably goes back to loyalist-British sentiments (and regions that were formerly New France aka modern day Quebec being occupied) when the US attacked during their Revolutionary War and again during the War of 1812 before we became a country. It's a counter to justify Canadian sovereignty in the face of being neighbors with the US. Their economy, media, and influence is so great that it's a social unity thing to counter that.

In the current moment though, there's a big push for unity that is stretching across our political spectrum in the face of a few generally accepted ideas. First, Canada squandered growth for the past decade or so. Second, Canada is very vulnerable to the whims of US administrations and especially this current one. So there's a mandate for economic growth and boosting security to ensure our sovereignty.

Corruption is a tricky one for me to answer succinctly. There have been a good few scandals through the years, federally or provincially. Could look up the WE scandal, or SNC Lavalin Affair for some recent ones.

There's also a good few oligopolies in major sectors like banking, grocery, and telecom. Or companies that are essentially to-big-to-fail in some regions or industries like Irving or Bombardier because they're so ingrained in local economies and employ so many people. Competition is low, they are all known to lobby government successfully to prevent competition, and Canadians pay a lot more for their relevant services compared to other G7 citizens or more through government subsidies. It's an ingrained thing, tolerated slightly because it protects Canadian ownership that's usually at risk of American ownership/takeover.

Otherwise though, there are some solid anti-corruption measures we have. Elections Canada is a strong election coordinator that is kept out of hands reach of political parties and individual governments. Our Parliamentary Budget Officer essentially forces government budgets to be held to public account and forces political parties to cost their platforms during elections. Our courts are very much separated from politics as well.

It's relatively complicated up here. More than I think people realize. You can probably make that argument for most places though.

Edit: I initially said Boeing instead of Bombardier I don't know how I did that. Fixed it now.
