I have not yet received ITA. I will get ITA in next draw. I got letter from my Organization stating all details of my employment in Canada.
Yes, I would like to get 50 points.
So once your contract is over what is going to happen? IMO you shouldn't be claiming those 50 points.
As long as you get an ITA and submit your application before your work permit expires you can apply for a bridge open work permit and remain in Canada while on implied status.
