I asked a question about NEXUS (frequent traveller program) at the CBP Info Center and received a response in about 3 days. As a Canadian with a criminal record, if I have an I-194 waiver, can I apply for and be granted a NEXUS card? Thank you for contacting the CBP Info Center. If you have a waiver, it is unlikely that you will be eligible for NEXUS membership based off of the general eligibility requirements and checks (ie: criminal background check).
