I would have to think SG can easily pull off a lower tax rate though. You're the size of Toronto only. Our infrastructure is spread, we're unconsolidated, vastly different systems Province to Province creating inconsistency, just a myriad of issues with our size and minimal population.
Canada is going to be an inefficient country, its the trade-off of having a low population over a massive beautiful landmass. Obviously we could let in other countries or ourselves completely rape it for its natural resources and bolster for a period of time, but that does not appear to be what the majority of Canadians want.
SG is smaller than Rhode Island.
42 KM × 23 KM. I think, if I remember correctly.
Most Expats will feel extremely uncomfortable with the heat, humidity and
freedom 
SG is efficient because it is tiny. No natural resources whatsoever and surrounded by 280 million Muslims.
There is absolutely no beauty or landscape in SG.
But you can easily fly to Thailand , Philippines, Bali, New Zealand or Australia. Not expensive.
You won't like SG. Work for 10 years or so get the money get connections for SEA or East Asia business and retreat back to Canada or wherever. That's usually what expats do.
