I am in Toronto. This shrub is in bloom now and the bright pink flowers morph into crab apple size fruit in the fall. The shrub is in the sunny and I would suggest growing nicely in clay soil. It is an old specimen as we have lived in our house for over 30 years and the shrub was in the yard when we moved in.
Thank you for your question to Toronto Master Gardeners.
Based on your photograph, we believe that it is a Flowering Quince (Chaenomeles japonica).
Enjoy the growing season.
