Are the EZM and MP Meter Paks Dual Listed for both UL and CSA?

No. As a general rule (a few exceptions do apply, consult you local Utility for their specific requirements), UL Listed Meter Centers are configured as HOT Sequenced Metering, and
CSA Listed Meter Centers are configured as COLD Sequenced Metering.
Hot and Cold Sequence has to do with the location of each individual Tenant Circuit Breaker in relationship with each Tenant`s Meter Socket/Watt-Hour Meter position.
For Hot Sequence, when the Tenant Circuit Breaker is OFF current continues to flow through the upstream Meter Socket/Watt-Hour Meter (the Meter and Meter Socket remain Hot).
For Cold Sequence, when the Tenant Circuit Breaker is OFF current no longer flows to the downstream Meter Socket/Watt-Hour Meter (the Meter and Meter Socket is now considered to be Cold).
