The park features a large playground, a wading pool, a pizza oven, a basketball court, and an outdoor ice skating rink in the winter.

[2] The park is home to the Clay & Paper Theatre which stages outdoor plays in the summer as well as special events at other times of the year.

In 1998 artist Gene Threndyle in partnership with the Friends of Dufferin Grove Park created a series of gardens and a fountain marking the path of Denison Creek.

These ruins were identified in 2020 by artist and amateur historian Andrew Lochhead, and confirmed by Threndyle, as the long-lost remains of the second Toronto Custom House (1876-1919) designed by Richard Windeyer.

[5] The ruins, mostly keystones and some capitals, represent one of the few remaining local examples of the work of one of nineteenth century Ontario's most important and prolific architects.
