Canada still has a lot of immigrants, if they wanted to be Canadian, they could go that route. But citizenship should be more than 'access to real estate and shopping malls'.

I'd simply make it so that residences (and real estate ownership), and maybe some other things like their financial positions (even like regular current accounts) are within the 'New Singapore' but otherwise they can go where they want and do as they please in Canada without any kind of border or whatever. And try to make a deal with US so that residents also have 'Canadian-like' access to the US, meaning visa free travel etc..

People who wanted to live in Van or Vic could apply for citizenship.
