Level 1 (Continue radiation)	Patients already on treatment at the onset of the COVID-19 pandemic will continue treatment unless they become COVID-19 positive (COVID+) or a person under investigation (PUI). Patients who convert to COVID+/PUI status will be placed on a treatment break unless they meet other criteria for urgent treatment. This level allows radiation therapy treatment for emergency and urgent patients for whom alternative management is not possible. Patients with highly symptomatic metastatic disease who are deemed by their physician to have a life expectancy of at least 3 to 6 months and those with rapidly progressing potentially curable cancer will be treated. Please refer to Table 1 for disease site–specific criteria for level 1.
Level 2 (Short delay of radiation acceptable if needed)	Routine situations requiring radiation therapy. Within each disease site, specific recommendations have been made. Patients should be contacted at frequent intervals to ensure they have not progressed to level 1.
Level 3 (Hold radiation)	It may be possible to delay these cases until the pandemic is over or omit radiation altogether. These are patients with benign disease or patients amenable to other therapy first (eg, systemic therapy or surgery when appropriate).

• Level 1 patients will be treated as described in Table 1.

• Level 2 patients will follow a structure determined by the disease site team leader and may have a delay in the initiation of treatment if needed.

• Level 3 patients will receive a video consultation with intervention delayed until after the pandemic has been cleared, if appropriate.
