It could be, however, that use of channel 37 for TV in Canada in some areas near the US border would in fact be forbidden, if the authorities (Canada's "FCC") thought a Canadian station on that channel might interfere with U. S. radio astronomy operations.

Besides the somewhat spotty ban, receiver makers probably found it easier to include the capability rather than explain to buyers that they didn't need it.
