Ontario Parks pass.

Summary/Review: "A daily vehicle permit is a great way to explore a provincial park for the day. Bike, hike, swim, picnic and make some magical outdoor memories. Includes entry at any operating provincial park for one vehicle and its passengers. Most permits are valid from 8:00 am to 10:00 pm, but can vary by park. Enjoy a park in every season. Daily vehicle permits are available year round – each park has its own operating dates so check ahead to plan your adventure"--ontarioparks.com/dayuse.
