That would suck.
Right now I am getting WT+ (T class) YYZ-LHR-ISB fares for C$3300.00 per ticket (which will bring the cost down to around C$1800 per person with this offer), and I can't get any availability on other airlines under $3-4k per person in Y.
The W fares, however, are approaching C$5000 per ticket - too expensive
