One common question that people ask me about cremation is whether or not it is illegal to scatter ashes. Here is information directly from the Government of Ontario website. ..
“The practice of scattering cremated ashes is an integral part of religious burial ceremonies for several faith communities in Ontario. Any individuals or families who wish to scatter the cremated ashes of their loved ones on Crown land and Crown land covered by water in Ontario can do so.
Individuals and families are permitted to scatter cremated ashes on unoccupied Crown land, and those Crown lands covered by water. There is no need to obtain government consent to scatter cremated ashes on or in such areas, which include provincial parks and conservation reserves, and the Great Lakes. Individuals wishing to scatter cremated ashes on private land, or private land covered by water, must obtain the owner’s consent.
In all cases of scattering cremated ashes, it is expected that ceremonies will be conducted in an environmentally responsible manner. Individuals and family members who scatter cremated ashes should ensure that only a handful of leaves and flowers – if they are a necessary component of the religious burial ceremony – accompany the scattering of these ashes.”
