When did you exactly submit your application Feb __, 2008?
If your case is under the simplified process, you should have received the letter from CIC with your file number by now and the letter will tell you when they started to process your application and how long is your waiting time.
You can use the file number to double check in cic website under the online services, and it will show the status... ofcourse, if you trust your agent that much, just believe in what they say but will not cause you anything anyway to double check right?
Under "Online services"
Click the "Client Application Status" and you will see this page. https://services3.cic.gc.ca/ecas/?app=ecas&lang=en
then just follow the instruction.
As I know though, that if you are already under the new policy which is on or after Feb 27, 2008, they will not start the process until they have released the list of in-demand/urgent skills required in Canada. I've read that they will release it by Aug. 15.
Hopes this helps!
