If you mean entire country, I would rank as follows:
1. Switzerland
2. Belgium
3. France
4. Canada
If you just mean French speaking parts then
1. France
2. Quebec
3. French part of Switzerland
4. Wallonia
I agree with you on the French speaking parts, but not on the countries as a whole
On the entire countries it's:
1. Switzerland
2. France
3. Belgium
4. Canada
I'd say until the last quarter of a century or so, Belgium was definitely more conservative than France, but Belgium has really liberalized and secularized in the last 20-30 years (think of it kind of like Ireland)
And funnily enough, Flanders is quite economically rightwing and quite nationalist/anti immigration, but it's probably the more socially liberal half of Belgium. Belgian politics aren't straightforward in terms of comparisons.
But even then, even comparing the immigration/citizenship laws for example, Belgium has more liberal ones than France, and in terms of say abortion laws, Belgium basically has the same ones as France (that being said, abortion was illegal in Belgium). Belgium also legalized gay marriage first, with the majority of opposition coming from Wallonia. France got to it a decade later with a lot more opposition.
And then even on economics/fiscal policy they're quite similar. Really the only thing that really sticks out as being more conservative in Belgium at this point is they still have their monarchy while France doesn't.
