It sounds as though the amplifier was subjected to serious overvoltage or simply has a switch failure. The 3B-ST/NT-212 design is simple and fairly rugged, but even the newest of these are getting rather long in the tooth. Service and shipping heavy equipment to Canada can be expensive. If the problem is only the power switch, the repair should be simple and the part inexpensive. Testing with a dummy load and a multimeter to (measure the voltage delivered to the load) should indicate if the output section is damaged. Using a loudspeaker to test the amplifier risks damage to the both, but is also a possibility.
