Ottawa is 5 hours behind London right now. Flying west gives hours back: you can arrive at a local time earlier than you left, which most people adjust to more easily than the eastbound trip.
Crossing a border: entry rules for Canada depend on your nationality and change without much notice, so we do not print them here. Check the IATA Travel Centre — the same passport and visa database airlines check at the gate — and confirm your passport has enough validity left, since many countries require six months beyond your return date.
