We'll look into it, and I thank you for the suggestion.
We are looking at cards that are issued by government--I think NEXUS is, I'm not familiar with it, but I think it is--cards that are related to an ID of a particular individual, not a group of individuals, and cards that enable that individual to do something, so if it fits into that category.... I would welcome suggestions of other cards that fit into that category. As the point was made here, people do like clarity; it helps them, so the more government-issued IDs we could actually list, the better. That's not to say that they're government IDs; some that are not there may be valid, but people do want them to see what they are.
We'll look into NEXUS and anything else you care to suggest. That's welcome.
We are getting suggestions from different parts of Canada and we're examining each one. We're trying to make it as easy for people as possible to comply with the rule.
