Artists have long painted outdoors, but by the mid-nineteenth century, working in natural light became particularly important to the Barbizon School and the Impressionists. This trend soon took root in Canada, which already had a tradition of painting out-of-doors that was connected to military pursuits. This exhibition looks at the work of some of the nation’s best-loved plein air artists, and features important views of the London area--of the Thames River, well known edifices, early neighbourhoods, and more -- by historical and contemporary painters.
