The park is situated on land the Fosters (Ed and Jill) sold to the City of Parksville in 1994, on the condition that it was turned into a park. The house, located in the park, was built in 1957 by the Fosters, and is now the caretaker residence.

Friends of Foster Park was started by many friends of the Fosters and was registered as a society in 1995. The Friends of Foster Park society has worked tirelessly to speak up on behalf of the park and gather community support for various projects within the park.

In 2015, a PowerPoint presentation of the history of Foster Park was updated. You can download a pdf version of the presentation here.
