Who would you consult? First off, there's an organization in Toronto called the Ontario Multifaith Council. Various religious groups come together to discuss areas of mutual concern. I don't know if that exists nationally, but consulting various faiths and cultural authorities to address the multitude of concerns they have when planning their funerals I think would be a good step.
I think you have a wealth of knowledge among the funeral directors of Canada that practise this day in and day out. Funeral directors cooperate readily with uniformed personnel, be they fire personnel or police services. I think there are a significant number of Canadians who have a great deal of expertise in this regard, and I think they could easily generate a group to discuss this and come up with a consolidated program.
In terms of how to put it on the website and make it easy to read, having various options in point form I think would be perfect, because in all likelihood, as we've found with funeral services, this information may well be required on a Saturday afternoon in Prince George, British Columbia.
I didn't clearly understand what the phone-book approach meant. We want something we can refer to, in areas of Canada where there aren't experts readily available to interpret what should normally happen, so that we can put it into practice.
