Good news, you are allowed to scatter ashes on Crown land in the Ontario area that is unoccupied – including those covered by water. Even better you don’t need a permit. Crown land includes provincial parks and conservation reserves, and the Great Lakes.
The Authorities ask that you carry out any ceremony an environmentally sensitive way and that if accompanying leaves or flowers that are necessary for religious rites, then these be kept to the minimum.
Individuals wishing to scatter cremated ashes on private land, or private land covered by water, must obtain the owner’s consent.
