Hospitals in BC cancelled elective surgery across the province yet only certain regions are struggling to provide service. The reason for the struggles is a combination of lack of staff (illness, stress, leave without pay) and increased need to provide support to those infected with covid. It is not one problem, its many and it depends on where you look.
My sister works on the surgical dept in my city. This is what she told me is going on. They are not overrun with covid cases there, they are short staffed.
