Before you go
Fee amounts and trail closures at conservation areas change seasonally, so it’s worth a quick check of the linked source page before you drive out. Most conservation authorities around the GTA cap leashes at 2 metres (about 6 feet) — bring a standard leash rather than a long training lead. Pack water, a collapsible bowl, and check our pet travel checklist before a longer hike.
FAQs

The Mast Trail in Rouge National Urban Park, about 30–35 minutes from downtown, explicitly allows leashed dogs and is free to enter.
Do conservation areas near Toronto charge a fee for hiking?
Most TRCA, Conservation Halton, and Credit Valley Conservation properties charge $8–$9 per adult, plus HST. Rouge National Urban Park is free.
What leash length is required on these trails?
Most conservation authorities cap leashes at 2 metres, roughly 6 feet. A standard walking leash works; long training leads generally aren’t compliant.
Are there any trail closures to know about right now?

Do I need to book ahead to hike with my dog at a Conservation Halton park?
Reservations are recommended (with a small discount for booking online) but not required for a day visit to Rattlesnake Point, Crawford Lake, or Hilton Falls.
