Art lovers of Toronto, take heed. You have only a few days left in which to witness the comeback of a storied Canadian artist.

Milly Ristvedt was, in the 1960s and ’70s, a practitioner of abstract expressionism, in the vein of Mark Rothko. And while her work can be seen at the Art Gallery of Ontario, the Musée d’Art Contemporain de Montréal, the Boston Museum of Fine Arts, and in art textbooks across Canada, it has been over  decade since Ristvedt has shown her work in a public gallery.

Toronto’s Walnut Contemporary gallery marks Ristved’s return with “Breathing Space,” a showcase of her new paintings. Learn more about Ristved and “Breathing Space,” but don’t dally. The showcase closes Apr. 27.
