The Sydenham river begins at the edge of Ontario, closer to Detroit than Toronto, and runs through a smattering of small towns along the border. It’s a place of freshwater mussels and sprawling farmland. It’s also where Larry Towell has spent his entire life. He grew up along the river in rural Lambton County and, in 1975, he salvaged lumber from a bulldozed barn and built a raft. He perched a shed on top and floated down the waters. He wrote songs; he lived off catfish. After graduating from York University’s visual arts program, he spent two solitary years on the raft. “Being rooted in your own life gives you a position to look outward,” he says. Look outward he did: Towell spent the next 40 years capturing images at home and abroad, more than a hundred of which will be on view in Boundaries, a retrospective running until March 14, 2026, at the Judith and Norman Alix Art Gallery in Sarnia, Ontario.

He moved on to Guatemala, where he documented soldiers, protesters and relatives of the “disappeared”—people who’d been abducted and likely murdered by government forces. In El Salvador, he boarded an old school bus bound for the far side of the river, occupied by the Farabundo Martí National Liberation Front, known as the FMLN. When government soldiers searched the vehicle, Towell crawled onto the roof. Nobody inside said a word. When they crossed the river, he found himself in guerrilla country. He spoke to campesinos and FMLN fighters who came into town and loitered in the streets. And he photographed them.

In 1988, Towell sent his shots to the world-renowned Magnum agency. That year, he became their first........
