Quick answer: Some of the best low-key things to do in London, Ontario after a little cannabis are walking the Thames Valley Parkway and Springbank Park, browsing Museum London (free admission), joining a free public night at Western’s Cronyn Observatory, grazing your way through Covent Garden Market, or staying in for a movie or game night. Consume at home or where it’s allowed, keep the amount low, and never drive. You must be 19+.
London has plenty of easygoing things to do that pair well with a relaxed mood: long river trails, a free art gallery, a historic market and a university observatory that opens to the public. Here’s a local’s list, with the practical rules so your day stays fun and legal.
Before You Head Out
- Consume where it’s allowed. Not inside museums, markets, restaurants or on patios, and not within 20 m of playgrounds or school grounds. See where you can smoke weed in London.
- Start low. A puff or two, or 2.5 mg of THC in an edible, is plenty for being out in public. Edibles can take up to 2 hours to kick in.
- Don’t drive. Walk, take the LTC bus, or use a taxi or rideshare.
- Bring water and snacks, and dress for London weather.
1. Walk the Thames Valley Parkway
The Thames Valley Parkway is London’s main multi-use path: 45 km of paved trail along the Thames River, connecting to more than 150 km of other pathways across the city. It’s an easy, scenic walk at any pace. Springbank Park is a favourite stretch; the City notes some Springbank sections may close at times for safety, with signed detours, so follow the signs.
2. Browse Museum London (Free)
Museum London, at 421 Ridout Street North by the forks of the Thames, has free admission. It’s open Tuesday to Sunday from 11 AM to 5 PM, with a late night until 8 PM on Thursdays, and it’s closed Mondays. Art can feel extra absorbing when you’re relaxed, but consume beforehand, keep it light, and be respectful of other visitors.
3. Stargaze at Western’s Cronyn Observatory
Western University’s Hume Cronyn Memorial Observatory runs free, drop-in public nights, usually on Saturdays, for people of all ages to explore astronomy. Upcoming dates listed include Saturday, November 14 and Saturday, December 12, 2026. Check the observatory’s website before you go, since events depend on the schedule and sometimes the weather.
4. Graze Covent Garden Market
Downtown’s Covent Garden Market has been a London food market since 1845, with farmers, specialty food vendors and local producers under one roof. It’s the perfect munchies mission. Check the market’s hours before you go, and remember you can’t consume cannabis inside. Want more food ideas? See our guide to the best munchies spots in London, Ontario.
5. Stroll Downtown and Dundas Place
Dundas Place, the pedestrian-friendly stretch of Dundas Street downtown, is an easy place to wander, people-watch and grab a coffee. If caffeine is part of your plan, read our tips on coffee and weed first.
6. Catch Live Music
London has a busy live music scene, from downtown venues to summer festivals in Victoria Park and Harris Park. Check each venue’s cannabis policy first; most indoor venues don’t allow it. Our guides to weed gummies for concerts and whether weed makes you a better dancer have more tips.
7. Stay In: Movies, Games and Cooking
When London winters hit, the best plan is often at home. Line up a movie marathon, try our list of the best video games to play when high, or cook something with homemade CBD butter. Need supplies? Weekday orders placed before noon are delivered the same day in London.
If You Overdo It
Find a quiet spot, sip water, and have a friend stay with you. It will pass. Our guide on what to do if you’re too high walks you through it, and dealing with dry mouth helps on long walks. For the full rules, see Ontario cannabis laws.
