There are official details about what docs one should take along when going on CIC website.
However, basically it is a list (and copy) of all items you are taking along, your actual documents (passport, letter of introduction (that the embassy will give you as proof of acceptance for work permit, LMO, Job offer etc.).
You should tell them how much money exactly you are carrying specifically if it is more than 10k CAD.
Also you need to have your employer contact details including address, phone number etc.
It is likely that the visa officer would ask you of employer details and might as well call them up to confirm your case before actually issuing a temp work permit.
