Most recently the FCC added the Multi-Use Radio (MURS) solution. Superhigh frequency for devices are comparable in Canada, however MURS can not be utilized there.
Back when consumer cordless products were first introduced, these wireless products utilized the 49MHz frequency spectrum.

These quiet codes maintain your radios peaceful unless an additional radio is configured on the same channel and silent code.
