For some residents across Toronto, this tree’s fruit is anything but sweet
An increasingly common non-native tree species in Toronto has become a point of contention for local homeowners. The female ginkgo tree, introduced to the city from China several decades ago, is now reaching maturity, leading to an annual autumn phenomenon that residents describe as a significant nuisance.
For residents like Alan Page, a Leslieville homeowner for over 20 years, the ginkgo tree in his backyard has shifted from a benign landscape feature to a source of persistent odor and maintenance issues. The tree produces fruit every October that is both sticky and notoriously foul-smelling, with residents and arborists alike comparing the scent to a mixture of dog waste and vomit.
The issue has reached the municipal level, as residents seek permission to remove healthy ginkgo trees from their private property. Currently, city bylaws require a permit for the removal of any tree with a diameter of 30 cm or greater, with potential fines for unauthorized removal reaching up to $100,000. These regulations are part of a broader city strategy to increase Toronto’s tree canopy to 40 percent by 2050.
City forestry staff have thus far maintained a firm stance, recommending that appeals for removal be denied. The city argues that these trees provide essential aesthetic, social, and economic benefits to the urban forest. However, the pressure on local officials is mounting. Coun. Josh Matlow has requested that forestry staff explore creative solutions for residents struggling with the noxious fruit, suggesting that the city may need to reconsider its rigid approach to these specific trees.
Future Implications
The situation may evolve as more female ginkgo trees reach maturity across the city. If city council chooses to follow the recommendation to deny removal appeals, residents may continue to face the challenges of decaying fruit, which attracts insects and local wildlife. Conversely, if the council decides to loosen removal rules, as suggested by Coun. Matlow, it could set a precedent for managing other non-native species that pose similar quality-of-life concerns.
A possible next step involves the forestry staff report requested by council, which is expected by 2027. In the interim, homeowners like Page, who has offered to plant five new trees to replace one removed ginkgo, may continue to wait for a policy shift that balances environmental mandates with the concerns of those living in the shadow of these trees.
Frequently Asked Questions
Why is the ginkgo tree suddenly causing problems for homeowners?
The trees were planted several decades ago and are only now reaching maturity. As they mature, the female trees have begun producing fruit, which is responsible for the foul odor and sticky residue.
Can homeowners simply cut down the tree if it is on their property?
No. A permit is required to remove any tree with a diameter of 30 cm or greater, even on private land. Unauthorized removal can result in fines of up to $100,000.
What is the city’s current goal for its tree canopy?
The city is working toward achieving 40 percent tree canopy coverage by 2050. Currently, the canopy is estimated to be at approximately 30 percent.
How should a city balance the need for a robust urban forest with the daily comfort of its residents?
