There are also similar versions of this fare from YYZ / YUL, ~$3300 r/t a/i. Fare basis PLU7WCA2. They can be routed through JFK / ORD to have the long legs on the new 777-300ER; also possible to build in a stopover in TYO + another in the US / CA.
For whatever reason Matrix has a tough time pricing these, but they are bookable- I have one ticketed.
