Hi Zakout76, if your IELTS Exam is prior to Nov.28, 2008 then it is no longer valid. Remember that the test is valid for 1 year. If you are apllying now for FSW1 then your test should be from Jan.2009 at the most.
For initial application, you do not need to sit for IELTS. You could claim the 5 points you need to make it to 67 and if you receive AOR, during the 120 period prior to sending the full documents to your local visa office, re-take IELTS. Also, the better your english skills are, the easier it´ll be to settle in Canada once you arrive. No use in going if you can´t speak the language well...in my opinion.
Good Luck!
