What with the down American economy and the SARS scare keeping many tourists out of Ontario, the last couple of years have been a struggle for the Shaw and Stratford festivals, southern Ontario’s duelling theater showcases. The numbers on the latest season are out this week, and Stratford posted a modest surplus, while Shaw announced its first deficit in a decade. Still, Stratford exceeded 600,000 ticket-buyers for the fourth year in a row, even after having to cancel six shows as a result of the massive power outage which hit the northeast in August.
