Culture Days is a Canada wide movement to promote art and culture. It is happening September 30, October 1st and October 2nd. There are a wide variety of activities in Toronto, across Ontario and across Canada. At the moment some of them are still accepting participants for activities or you can create your own activity/venue and submit it for inclusion in the event.
The list is quite extensive and a bit overwhelming. I suggest using the Advanced Activities Search if you’re trying to find events in a specific city. There is also a list of venues that are seeking participants and if you have a venue you would like to offer you can do that too.
One thing that looked pretty cool was free lamp-working at Tank Studio in the Distillery District. I’ve done lamp-working (glass bead making) before and it’s not the easiest thing but it is a lot of fun!
Here is the Canada wide link, go to the Activities link and use the Advanced search option to find events in your area:
