You'll get fewer points if you try to emigrate to Canada as a professional when you're 45+ years old.
Have many friends overseas who are still working & not as dishwashers
Don't hear complaints from them about this as for many of them its something to do. Not everyone can sit around & do nothing
Have you heards the saying "You can't teach an old dog new tricks"
Its harder to adjust to new surroundings when your older. The only person I know who returned from Canada was a nurse in her 40's. She told me it was the cold but it could also be that she was lonely(she's single). If you go there with the right attitude you'll soon have a circle of good friends.
Working in Canada is less stressful than Spore. I'm reminded of this whenever I meet up with old schoolmates who come back to Spore for holidays. They look so much younger & fitter, and they smile more. When I was working in Canada it was barbecues at the bosses house, house warming parties at a colleagues house, fishing trips,.... Life is more than just about work
I remember going out with friends after work, after all office hours was only from 8 to 4pm.
If you have kids I'm sure you'll want them to have an NSless life
You'll have more quality time with them & if you are kiasu about education you can send them to the many elite schools, unlike in Spore where only foreigners are allowed in those International schools.
Canada has many fine Universities & they offer scholarships to PR & citizens. I remember meeting a korean chamber maid at the hotel I was staying & she proudly told me about her son who'd won a scholarship to study in the US.
As a Canadian you can work in Europe & US
The PAP gov't allows anyone to work in Spore but have not bothered to get the same concessions from foreign gov'ts.
You can of course wait until 50 before deciding to emigrate but many Sporeans can't wait that long
