I've lived here, UK, Canada (East Coast) and the USA (West Coast). If you've enjoyed Switzerland you'll probably appreciate Canada. The open spaces, the respect for the environment but freedom as an individual. Federal tax rates have come down in the last couple of years. The Government is running a surplus because of the revenues from natural resources but you'll also need to consider the additional bite of provincial taxes. Consider BC - beautiful place to live, laid back but a vibrant economy.
