HRSDC confirmation

[fedone]

Hello everybody,
Probably at the end of May I will go to Ontario with an open work permit valid for six months.
The idea I have is to find a job and apply for an extension of my stay. The problem I have is that I will have to ask for a HRSDC confirmation.
Question is:
1) How can be difficult to get any confirmation?
2) I know that a permanent contract is needed. Is so difficult to get it?
3) Do you think I could go through a "practice firm" program to get a job quicker? Or it is a bed idea?
4) Do you have any advices?

Many thanks for your time and consideration

Regards
