Personally, I'd suggest you do both of those things. No, it isn't unethical; the retirement residence construction will take a while in any event, and you are under no obligation to take it if it doesn't suit you or your needs. Don't worry; it won't go begging. This is just the beginning of the boomer bump.
I'll try to find more information from l'Association québécoise pour les droits des retraitéEs (AQDR) and La Fédération de l'Âge d'or du Québec (FADOQ). I think they have some information in English; if not, I can summarize it for you.
