How should I record my payment to my sub contracted workers vs the employees option that QBO offers?

If I'm not mistaken, sub-contracted workers (non-employees) are self-employed.  Therefore they should be giving you an invoice for their services, and you should enter them as a Supplier/Vendor and pay their bills accordingly.  Just beware if they are working solely for you and have no other 'clients', the relationship could be deemed by CRA to be employer/employee and you would then be on the hook for all their CPP and EI, both portions.
