The only active bases outside of CAN right now are primarily...
for the A330 crowd there are two bases within Australia.
for the 787 last week they finally announced AKL as a base and it will be built up shortly.
YVR nor any European bases have began.
There are currently NO bases for the 777.
There are rumours that YVR may switch back to the 777 and then it or LAX may become a base, but for now any 777 driver (there are 35 foreign pilots on 77) must either move to CAN or commute.
Hope that helps.
