Based on what i have seen in the past, its not always the case where your file moved to LVO for final processing. Even if you look at old threads...around year old, while it can generally be assumed that final processing happens at LVO, there are many cases of Abu Dhabi cases being handled by the london office etc. Its about load sharing and since everything is digital and the file never physically moves anywhere thanks to EE, this can be alloted to anyone with excess capacity and that explains why London used to handle many outland cases a year back. I think that they now probably have the option or the capacity to handle cases at Ottawa too! So my conclusion is that USUALLY, cases are handled in the final stage at LVO but not necessarily. They will decide where it finally goes based on division of labour. They are just sharing the load and why not. It doesn't matter who processes it since I am sure the goal is to finish it as soon as they can instead of burdening it with an overworked LVO!
