Welcome to the website of the Ontario Plein Air Society (OPAS)

If you are a plein air artist practicing in Ontario, then you should be a member of OPAS. OPAS is the one central organizing body for plein air artists in this province. By joining and participating, you help raise the profile of plein air painting in Ontario and beyond.

As a member you can post paint-outs, events and competitions. You can check out a list of Canadian plein air events, ask other members for input on any kind of questions you have and, of course, post your own work for all to see.

It's easy to join. Click the Sign Up link at the top of the window and fill in the forms that follow. Membership is $30 per year.

Everyone is welcome to browse through the site. There is a large number of very accomplished artists here who sell to the public. 

For art groups looking for instructors, contact us and we will put you in touch with members who teach.
