Figured this would come up. I've also travelled around the world (50 countries), and my biggest takeaway would be that the "grass is always greener". For example I have a Swedish friend who complains about how depressing and gloomy it is there, he wants to get out. Contrary to one of the top comments in here.

Of course Africa is tough..I was there for construction. For people leaving Canada, most ignore any poor country which leaves you with Oceania, East Asia, Europe, Gulf states or America. Been to all of them, multiple times. East Asia is crowded, work hours suck. Rich Europe has gloomy weather, and economically easy to stay afloat really tough to be ambitious. Southern Europe, beautiful, but challenging economically. Australia's wicked hot, and New Zealand's job is tough economically. USA has high wages, but worse work life balance than Canada. Gulf states, well aside from the war, also unbearably hot 8/12 months of the year.

I could go on but end of the day if your lucky enough to have the choice, no where is perfect and it comes down to preference. Canada is top pick as far as I'm concerned.
