Its a switch! Power, ground and signal to ecm. If cluster is bad, it's not the actual cause. Its just not providing one of those 3 things. In other words, shouldn't matter if Canadian or US cluster.

Its just dial markings. Everything else is just signal. Does ECM care how fast you going...YES. Does it care if you are doing KMH or MPH? Don't know, but it's just a conversion so both the same really.
