“CSA Approved” means that the product has been approved by CSA (Canadian Standards Association) to the appropriate CSA standard for that product.
“Approved to UL standards” means that the product has been approved by a third party test agency to the appropriate UL (Underwriter’s Laboratory) standard for that product. In this specific case, CSA did the evaluation to the UL standards.
