Global Entry Members at NEXUS/SENTRI Lanes
There are no additional requirements for a member to use the NEXUS lanes coming into the U.S. However, Global Entry cards are not valid for entry into Canada via the NEXUS lanes and kiosks; travelers must apply separately for NEXUS.

Travelling with non-NEXUS members: If you are travelling into Canada or the United States (U.S.) with non-NEXUS members, you must use the regular lanes. The driver is responsible for ensuring that all travellers in the vehicle are NEXUS members. If there is a non-NEXUS member in the vehicle, regardless of his/her age, it will result in the loss of the driver's NEXUS membership
Então, se você tentar isso com crianças sem cartões GE, você estará em apuros.
