Free events in Toronto this week are so novel, they'll make you happy you stayed in town for the final leg of summer. Learning to dance like the girls in Justin Bieber's "Sorry" video before heading to the beach to watch a movie on a floating big screen? Sign me up.

Here are my picks for things to do if you've spent all your money on a new air conditioner.

Beginner Bieber Dance Class at Union Summer (August 16)
You might have noticed the summer-long market happening outside of Union Station. Well it's more than just food stalls and (actually fun) entertainment. They're also helping improve your club life by giving a one-off Bieber dance class courtesy of the Underground Dance Centre. It starts at 8 p.m.

The Gata: Water Ceremony (August 18)
The streams and dripping fountains of Sherbourne Common are already very cool. Let this performance show make them ever cooler. Starting at 6:30 p.m., this three hour piece moves through the spaces of the park with voice, dance, and live music. Come and watch as you please.

Sail-in Cinema (August 18-20)
It's finally here! The outdoor movie series that you can watch via a massive floating screen out on Lake Ontario. Boats pull in to watch from the water as you watch from the shore of Sugar Beach. Pre-movie activities at 6 p.m., movies at sundown.

Final Tragically Hip concert screenings (August 20)
The list keeps growing, but check out the link above to see where you can watch this legendary moment in Canadian music history, all for free. Bring your tissues and singing voice; it's going to be an emotional ride with the band as they perform live from Kingston.

Open Streets (August 21)
Ever want to star in an action film about post-apocalyptic Toronto? Empty streets, only lucky survivors? A few rats... etc. Well now you mostly can. From 10 a.m. to 2 p.m., Bloor St. (from Dufferin to Parliament) and Yonge St. (from Bloor to Queen) will be closed to cars and opened solely for people. Run Free!
