Honestly, this happens every few months/years at YYZ and other Canadian airports. They "pilot" against Nexus to keep everything in the bags including liquids, electronics, etc. Then suddenly they will halt the pilot and go back to the usual MO. Rinse and repeat. While I love the current Nexus approach at YYZ, just chuck your bag in the bin and that's it, I'm not going to hold my breath this is the new 'standard' for more than a few weeks or month.
