In Canada, which bands may amateur radio operators use for radio control of models?

In Canada, amateur radio operators are permitted to use their frequencies for the radio control of models (like RC planes or cars) but with specific restrictions. The regulations stipulate that this activity is only allowed on amateur radio bands that are above 30 MHz. Frequencies below 30 MHz (the HF bands) are designed for long-distance propagation and are subject to congestion and unpredictable ionospheric skip. Limiting radio control to VHF, UHF, and higher bands ensures line-of-sight control and prevents accidental interference from distant operators, which could dangerously disrupt a model's operation.
