There are appear to be some fairly important schedule changes going on right now for Spring/Summer - and it feels more significant than what we may have experienced in previous years. There is another thread on equipment change within Eastern Canada (CRAs to DH4) and I have noticed a few weekend changes where they are swapping E75 SKY service between YOW-YYZ back to mainline. Those are the few I have noticed, but I am sure there is more that has yet to pop up!
