AC is constrained by Canadian legislation from sharing personal information without the individual's consent, other than using it for the purpose for which it was collected.

So it's OK to tell LH that Mr. X is connecting from ACxxx ex. YYZ, but it is not OK to tell LH that he lives at such and such an address for LH to mail him a promo flyer.

(AC can, however, mail anything it likes on behalf of LH).
