To commemorate Juneteenth today, Grotto and Core are inviting our community to learn and reflect about Black history as well as support local organizations and Black owned businesses.
Today, we'll be donating proceeds from our day passes to in Guelph, and in Cambridge.
We invite you to support, learn, and reflect today and every day.
