mould removal

I need advice on who to talk to and contact about mould or mildew removal. We have just taken possesion of and are about to move into a rental house in Edmonton only to discover there is a mould problem in the floors (carpeting) of the basement. While I cannot see the mould I can smell it, and the smell is overwhelming to me, we spent one weekend in the new house and myself and my children all ended up with coughing sneezing stuffy nose etc, the children moreso as they chose to play in the basement. Who can I contact about testing which type of mould, the severity of the problem, and removing it. I do not believe the new landlord will pay for the testing and removal until we prove there is a problem, and we are on a extremely limited budget with moving costs and such. They did offer to clean the floors but i know this will only be a very time limited bandaid solution. The carpets have foam matting beneath. I am scared to move any furniture to the new house but we must be out of the previous house by the end of June. (** note my husband is ill too but thinks it has nothing to do with the mould in the basement as he cannot smell it **)
