Canada 3000: And where are they now? Maybe they did not do all that well overall. Kaput 18 years ago. The story of many a LCC over the years in Canada.

Here it is from Wikipedia: On November 8, 2001 the company suddenly collapsed with no warning for travelers or employees. The company filed for bankruptcy, citing a downturn in air travel during the weeks following the September 11, 2001 terrorist attacks on the United States. The fleet was left grounded at various airports around the world, leaving 50,000 vacationers stranded. September 10, 2001 was a record booking day, but within a few days air traffic declined by 50%. The airline was offered a $75 million loan guarantee from the Canadian government under the condition of a 'viable business plan' being produced. By November 7, 2001, the airline had $260 million in debt, and only had $1.49 million in cash. In secret, it had applied to the Canada Labour Board for permission to cut labour costs by 30% by closing its Royal division immediately. The Board would not approve without union agreement. Union offers to cut 700 pilot and flight attendant positions did not provide enough savings immediately and the airline applied for bankruptcy protection on November 8, while it planned to continue flying. By the end of the day, airport authorities in Toronto and St. John's, Newfoundland has seized planes under court authority and the company directors decided to cease operations.
