Regulatory Recovery Surcharge for Canadian corporations

I recently negotiated a new contract with a tier1 for IP transit in Canada and just got the invoice. I saw a "new" Regulatory Recovery Surcharge of 10% the MRC (before taxes) that I've never seen before. Do any of my Canadian fellows on this list are paying this outrageous surcharge? Other than saying "it's in the MSA", our rep, their tax and billing department are not useful at all. The actual rate is not specified anywhere in the MSA or in the contract.
