I was on 3rd break during an international trip. I awoke to go to the bathroom. A flight attendant stopped me and asked if I knew what the issue with the plane was. After hearing this; I called to the front and asked what was going on. They said to come up and they would fill me in. I did. I sat down in the right seat and noticed we were on arrival at 20;000 FT somewhere over PA. I was told that we lost the left engine hydraulic pump; followed by the left hydraulic quantity over Canada. Checklist had been run; conferences calls made on SATCOM and landing data performed. The decision was made to land at destination and taxi to the gate. After reviewing checklist with the list of lost items; I saw nothing to prevent us from safely doing this. I accomplished the pilot not flying duties until an uneventful full stop.
B767 First Officer is informed by the flying crew upon returning from the third break; that the left hydraulic system has failed and the flight is continuing to destination.
