Sault and Seneca weed out the weaker pilots and students to assure a standard is met. This standard should, in an indeal situation allow someone to hire a Sault or Seneca grad and know they've got a quality pilot. When you pass UWO on your ability to fork out money to do extra training that takes away the exculisvity of the Sault and Seneca programs.
I started Sault with around 90 pilots, we finished with a handful over 20. If you think you're going to be one of the 70 that couldn't meet the standard, then I would suggest a pay as you go operation. If you're willing to work hard and apply yourself to the flying, go to Sault or Seneca. Your pilot education will be second to none within Canada.
