10 reasons with each building upon the previous (T.L.;D.R. in bold throughout):

1. Quebec hosts the second-largest french-speaking city in the world. With 8,6 million speakers in the whole province, of which about 85% are native french speakers, Québec is a destination that makes a lot of sense for French citizens who want to expatriate, but still continue to live in French.

2. For French people looking for an "american experience", Quebec is much more business friendly and pro-capitalist than France, while still being more progressive and collectivist than the rest of North-America. Hence, it's perceived as somewhat of a Goldilocks for ambitious French people, not as cutthroat capitalist as the US, but not as overbearing as France.

3. Because of common history, France and Quebec share a lot of reciprocity agreements that make professional mobility easier between both regions. French credentials and experiences are more likely to be appreciated and respected in Quebec vs. other parts of North America. The objective evaluation that allows migration to Quebec (distinct from the Canadian process), favours a French person or someone from a French culture quite simply. It's welcomes lots of french-africans, vietnamese, Haïtians, and people from other french cultures.

4. Lots of the province, which is already five time the size of France with a bit under 1/5th of its population, is wild and undeveloped territory with pristine wildlife and vistas. Quebec benefits from 4 sharply contrasting seasons which allow a whole range of activities and sports. In summary, you can own land for cheap, you can own lots of it, you can live away from it all, and you can enjoy a greater diversity of climates in comparison to France.

5. Although, Québécois have a reputation in North-America for being rude and opinionated. From the French perspective, Québécois are rather accommodating, reasonable and pleasant to be around. Often, French perceive their own society as one of extremes, while Québec is seen as more care-free and mellow. Both French and Québécois share that Mediterranean blood which enjoys and values passionate debate. French will argue with anyone, truth be told, but Québecois are amongst the few that understand implicitly the non-antagonistic nature of that method of communication when it comes from them. Both cultures are candide with their thoughts and opinions. There is little doublespeak. Expressing disagreement passionately and aggressively, but without malice, is very hard to grasp for many cultures. If French people could argue as well in english as they do in French, they'd get shot hours upon landing in some parts of the US. Instead, they just come across as snobbish as they think you a fool, but lack the means of explaining it to you.

6. The "accent" of French people is perceived as sophisticated in Québec and is seen as charming to most Québécois women, who are also more forward with their romantic interest than french women. French men are also seen as more open about their feelings. Québécois men on the other hand are perceived as being a bit more rugged, while also being more respectful of women and maybe less arrogant. French people don't struggle finding romantic partners in Québec. Québécois generally have no problem as individuals or as a society with people dating anyone, from anywhere.

7. Moving out of France often means a downgrade in terms of food options for most French expats, Québec however has a lot of the "essentials" at a comparable or at least acceptable level while offering other more novel food items that are unpretentious and pleasant to a French palate. Québécois enjoy wine, beer, cheese, bread, and other fine foodstuff that the French also consider essential.

8. Québec, for the size of its population, has had for decades now a very strong cultural output. If you were to look at Canada's showings in international festivals and competitions, you'll often find that 80% of the time Québécois talent is behind it. Especially if you look beyond the anglosphere. Quebec has many of its own cultural industries (cinema, TV, books, news, magazines, video games, art, poetry, theatre, music, performance arts) and many of its best products end up exporting themselves to France. Like people who romanticize Korean or Japanese culture, Quebec has its (small) share of French people who romanticize Quebec to an extent. Quebec from a French perspective is an intriguing proposition: a former french colony, abandoned for nearly 100s of years surrounded by "enemies" and the wilds, that somehow persisted, and has evolved into its own distinct society. Québec is seen as an interesting unknown.

9. A lot of the worst societal debates in France are simply not present in Québec. Many younger French people have very negative outlooks on their country. Québec seems unburdened by these troubles, while also being safe and peaceful. What the US use to represent to the anglosphere, a land of opportunity, is a quality that many French people still see in Québec. With the added bonus that Québec is one of the most safe and peace-loving societies on earth.

10. If you are a professionally ambitious french person, your name, your gender, your background really, truly, will never matter as much in Québec as what you accomplish. Compared to France, the work culture in Québec is significantly less tolerant of sexism, racism, classism, or anything similar. France, for all its qualities, has many glass ceilings that feel bulletproof for young professionals. France is a former colonizer, Québec a former colony, and that kind of shows in its hierarchical structures. France has a lot more family dynasties that monopolize politics, business, and the upper stratas of its society.
