Yes it is, according to an article from the Independent in the UK the flight also had 213 passengers on board. The BA 787's seat 214, that is one nice full flight. Perhaps BA can make a go of YYC still?
Despite this being a 787, keep in mind that if it was an engine fault that would be a Rolls Royce issue in this case (BA has their Trent 1000 engines on the 787).
