From what I'm seeing, reading and understanding, there's not going to be a move of the HQ anytime soon. CWB's asset growth has been middling and stagnant over the last two years, and it seems like National Bank is going to be using CWB as their vehicle for growth in Anglo Western Canada since they're mainly focused in Quebec.
It honestly could be good news in terms of growth, both in asset and jobs for the future, especially if they're trying to make the Big Five into the Big Six.
Personally wouldn't mind us as Anglo Montreal of the West in this regard.
