Detour Coffee began at a single counter on King Street West in downtown Dundas, and that counter still pours espresso under the same name. The roasting side of the business grew outward from here — beans now carry the Detour label well beyond Dundas — but the original address never became a showroom or a warehouse desk. It stayed a cafe, a storefront on the town's low-rise main street. Ordering is done at the counter, the coffee is the house's own, and the short kitchen menu is built to sit beside what's in the cup rather than upstage it.
The kitchen leans on sourdough from Dear Grain, whose loaves turn up under most of the lunch menu. A pesto chicken sandwich carries house pesto, garlic mayonnaise, sundried tomato, red onion and arugula on Country sourdough; a caprese sets Italian mozzarella against basil pesto and balsamic glaze on the same loaf; an open-faced egg salad — roasted red pepper, arugula and alfalfa sprouts — is built on toasted Silhouette. There is a ham and cheese croissant with Black Forest ham, Swiss, yellow cheddar and house dijonnaise, and a roasted beet and goat cheese salad with golden and red beets, spiced honey pecans and balsamic. Breakfast stays on all day: smashed avocado with cherry tomatoes, goat cheese and hot honey; a porridge bowl built from steel-cut oats, quinoa, hemp hearts, golden raisins and candied pecans; yogurt under house fruit compote and Morning Glory granola. The all-day list runs to a BLT, challah French toast and the house Detour Breakfast, and behind the espresso — cappuccino, latte, mocha — sit a London Fog and a maple oat milk latte, with scones and a buckwheat dark chocolate cookie on the pastry side.
What holds all of this together is a preference for making in house and buying the rest close by. The bread comes from one named bakery rather than a broadline supplier; the condiments — pesto, dijonnaise, hot honey, fruit compote — are made on site; and the produce-led plates rotate with the season instead of holding a fixed card year-round. It is the logic of a roaster carried into a kitchen: source narrowly, control the process, and let a few good inputs carry the plate. The result reads less like a coffee shop that added food as an afterthought and more like a kitchen that happens to share a counter with an espresso machine. The salad in July is not the salad in November, and that is the point.
Kaelin McCowan founded Detour, and the Dundas cafe was the first one, opening in January 2011. What began as a place to drink carefully made coffee turned into a roasting company; the beans that started as something to serve across the counter became a wholesale line. And yet the original storefront never got repurposed into something more corporate — it went on doing the thing it opened to do. Fifteen years later the counter still opens every morning at eight, and the kitchen still cooks off a menu that changes with what the season hands it.
The visit pattern is fixed and unfussy. The cafe runs daily from eight to five, but the kitchen stops at three, which makes the food a breakfast-and-lunch proposition rather than a dinner one. Guests order at the counter and carry it to a table inside or, in the warm months, out to the patio; there is takeout, delivery and order-ahead for anyone who would rather not sit down; and beer and wine are on hand for the late-afternoon stop that wants to slow down. By mid-afternoon the kitchen has gone quiet and it is coffee and a pastry until close — the shape the place kept from before there was a roasting company attached to its name.
Detour's first cafe has served King Street West since 2011, giving the roaster a long-standing neighbourhood home.
House-made condiments, seasonal produce and Dear Grain sourdough give the breakfast and lunch choices a clear point of view.
Indoor seating, a seasonal patio, takeout, delivery and order-ahead service cover both a sit-down cafe break and a practical meal to go.
