Metrocosm:

The globe displays one year of global air passenger traffic. The data comes from modeled estimates compiled for the Vector-borne Disease Airport Importation Risk project (available for download at WorldPop). In 2010, the year for which the data was modeled, there were roughly 30 million commercial flights around the world carrying about 2.8 billion passengers.

This is an incredible data visualization. You can click on individual countries to see their incoming/outgoing traffic (Canada’s is unsurprisingly small) or zoom in to see individual details.
