Foul-Smelling "Olives" in Ontario: Female Ginkgo Fruit

Question: Neighbor's tree drops 1-inch green fruits smelling like vomit/feces. What tree?

Answer

Female Ginkgo biloba (maidenhair tree). Fan-shaped leaves turn gold in fall. Fruits have foul-smelling pulp; nut inside is edible (Asian cuisine). Landscapers avoid females for this reason.
