Most of the $70 billion Canadian market, 60-odd percent of it, is from Canadians travelling within Canada domestically. The ability to incrementally increase that percentage faces a question mark, and it is a lower-yield market. In other words, a Canadian traveling in Canada is a lower-yield traveller than one from further away. The Canadian Tourism Commission and others in Canada, such as Ontario Travel and so on, are promoting more to the mid- and long-haul U.S. markets, those that are less price sensitive, because the close-in border just isn't coming back.
