The master tech did that -- he said the plug for the cluster is ok. He put an oscilloscope on various parts of the CAN BUS network and he said the relevant sensors and ECUs are sending signals correctly.
Given that the CAL IDs for US and Canadian cars are the same, he surmised that there's some firmware or other difference between the US and Canadian ECUs that codes the signals from the ABS sensors into miles and kms respectively. He thinks that the US and reprogrammed Canadian clusters just can't process the odometer message that the Canadian ECU is sending.
