With respect, I think your assertion that moving yards to an area you have designated is misplaced. The present yard serves industry centered on the Hamilton Harbour, and that access needs to continue. HOPA continues to invest in infrastructure in the harbour and projects further growth in tonnage and products. This is all ready a busy Great Lakes Port.
I am not sure of the lands you are designating for a new yard, but the idea may run into issues with protected farm lands in those areas related to the tender fruit growers. That I need to look at as I am working from memory here. I also assume somewhere there will be a budget for CN to move the yard,.
I understand that the waterfront land and access to waterfront is valuable. I get that and have argued for it elsewhere. In this case I think you also need to balance that need for these lands against the services provided to industry and employment in the immediate area, plus the greater reach of the port.
