ref letter -- past employer has changed his organisation

[nig]

I am applying under NOC 3111.One of my previous employer (then HOD) has changed his work place,works in a differnet hospital now.
Since the Ref Letter has to be on the letter head where I have worked with him,I contacted my past employer and informed him about it.He has prepared a ref letter on same hospital letter head (where I was working with him) but he can't put stamp of that hospital as he no longer works there nor can he use his present stamp as it has diffeent hospital name.He has put his desigantion as Ex-Hod. and signed the ref letter.what should I do about stamp part.
Also I don't have contract from this place of work.There was no such thing in place.If I arrange an employment letter, will that serve the purpose.What should be the contents of employment letter.
Any suggesstions please?

I think you should contact hospital where you had worked .
