The approach we took was to have panels of experts. That leaves over 30 modelling experts from across the country to look at more than one methodology. It's not a single model, but they work pretty much constantly to update what the model's parameters would be, based on published information but also based on the Canadian models around the country. It is not a singular methodology, but one that takes into account many different ones.
