Travelling to Singapore
Singapore is a small island nation south of Malaysia, near the equator. See http://wikitravel.org/en/Singapore. From Canada you can fly Vancouver-Tokyo-Singapore, Toronto-Hong Kong-Singapore, Chicago-Tokyo-Singapore, Chicago-L.A.-Singapore and such. While Singapore is not cheap to get to, travelling around South-East Asia is cheap from Singapore, with its low cost airlines: http://wikitravel.org/en/Discount_airlines_in_Asia#Southeast_Asia.
