Interestingly, some provinces place weekly or monthly limits on the purchase of tax-exempt smokes in order to combat this. However, their method of synchronizing the limits with retailers is laughably outdated and insecure (one province transmits drivers' license numbers and home addresses in plaintext using plain FTP or dial-up). Because of this, some retailers are able to forge the necessary ID to obtain limitless tax-exempt cigarettes which are then sold to non-Indians. Source: I worked as a network technician for several retailers across Canada who were later penalized for fraud of this sort. Yikes.
