The Nexus people at Halifax International - both US Customs and CBSA told me it was fine for Airports.
Did it last year on my way to and from the World Shoot in Florida - through Pearson.
Going to the US, I did nexus and when I met the officer to hand over my receipt, I declared I had firearms. She sent me into get them checked.
On the way home, I pressed the "I have firearms" button on the keyosk and went in and was sent in do my inspection.
Saved me time going into the US but coming home, the "efficient" baggage handlers at Pearson ensured that any convenience I gained from nexus was outweighed by the delay getting my bags.
Looks like land crossings are handled above.
In air mode you will make a declaration on the Nexus kiosk which says you have a firearm so the machine knows you required a mandatory inspection.
I have't flown with a gun since last October, but up to that point in time, in dozens of trips, I have never encountered a Nexus machine that had a question about firearms.

Unforeseen circumstances prevented me from hitting Custer today. Thanks for all the info.
It's curious to hear about the vastly different experiences. I did find on the Canadian site:
Restricted, Controlled and Prohibited Goods
If you have any goods that are considered to be restricted, controlled or prohibited, or if the goods you are importing require a permit, such as firearms, you may not use the NEXUS lane, in any mode.
Haven't found anything on the US side yet.

It asks you if you have marked "yes" to any questions on part A of the form, which is where the first question is "any firearms or weapons".
