Give the capital a day and a half on your way from Montréal to Toronto — a photographer's circuit built on rivers, locks and light.
You shoot remote coastlines and big geometry. Ottawa hands you a compact capital built on moving water — three rivers, a canal that climbs the city in a staircase of stone locks, bridges, a waterfall, and a Gothic parliament for a skyline. Here's a day and a half that keeps you in good light and never far from the water.
Wednesday, July 15 · Settle in, walk the old town, and cross the river for the shot you'll come home with.
Drop your bags at the design hotel in the middle of the Market — five minutes from the water-taxi jetty and walking distance to everything below.

Ottawa's oldest quarter and its liveliest few blocks — a patio lunch to land you in the city.

Walk the Hill's grounds (exteriors — Centre Block is mid-restoration), then down the flight of eight locks where the UNESCO-listed Rideau Canal staircases to the river beside the Château. The little Bytown Museum sits right in the lockstation.
Leading lines down the locks; the Château looming above; lock-keepers and canoes for scale.

Board the 100% electric Aqua-Taxi at the locks jetty and cross the Ottawa River to Gatineau — no schedule to chase, just a slow vantage you can't get on foot. (It also stops at Richmond Landing by the War Museum if you want to hop off.)
Mid-river is the spot: Parliament, the Alexandra Bridge truss and the Château stacked in one frame.

Douglas Cardinal's curved, fossil-stone building is a geometry study on its own, and the Grand Hall of totem poles is the best interior in the city. But the prize is the riverfront plaza: the postcard reverse-angle of Parliament across the water, ripening toward golden hour. Stay for the light.
Float back to the locks as the light turns gold.

Behind the National Gallery, this bluff is the sunset perch — an elevated sweep of Parliament, the river, the bridge and Gatineau beyond. Two minutes from the Gallery doors.
Dinner a short walk or quick ride from the hotel.
Tonight, Bluesfest at LeBreton Flats has Conan Gray headlining, with Natasha Bedingfield and fingerstyle guitarist Yasmin Williams down the bill — stage light and festival crowds are their own kind of frame. Otherwise the Andaz rooftop (Copper Spirits & Sights) is a quiet city-lights nightcap.
Thursday, July 16 · A morning on the water, then the city's best moving-water shot — before the train south.
If you're a first-light person, the locks and Nepean Point are a five-minute walk from the hotel for glass-calm frames before the city wakes.

Daily through the summer (~10:00, weather permitting): colour, ceremony and motion on Parliament Hill. A short walk from breakfast, and it sets up the next stop.
Tight on the bearskins and red tunics; wide for the column against the Gothic façade.

A 90-minute electric cruise from behind the National Arts Centre (1 Elgin St) up the canal to Dow's Lake and back — the canal, the Museum of Nature's "castle," and the lake basin delivered from the water.
Low water-level angles on the bridges and lock stations you walked yesterday — a different read on the same geometry.

A short hop to the Dow's Lake Pavilion for lunch on the water, the Dominion Arboretum's green hills rolling up behind it — or a five-minute stroll into Little Italy.

A short ride south to where the Rideau River pours over layered bedrock at Prince of Wales Falls — a quick, flat walk from the lot to the overlooks. The most dramatic moving water in the city, right in your seascape vocabulary.
Long-expose the cascade; the angled rock strata are the composition.

Back downtown: Moshe Safdie's glass-and-granite Great Hall is pure architecture, and Louise Bourgeois's giant spider Maman guards the door — one of the most photographed sculptures in the country. An easy indoor finale before the station.
Ottawa Station is a short ride from downtown — board well-fed and well-shot.
Base yourself downtown / ByWard and the whole circuit is on foot. All mid-to-upper range.
Heart of the Market, five minutes to the Aqua-Taxi jetty, the locks and the Gallery. A rooftop bar (Copper Spirits & Sights) with skyline views makes it a natural base for someone out chasing light — the walkable centre of gravity for this whole plan.
Stately and central, facing Confederation Park and the canal, steps from Elgin Street's restaurants and a flat walk to the Hill. A touch more traditional than the Andaz, reliably well-run.
Roomy suite layouts beside the Rideau Centre and a short walk to the Market — good value and extra space to spread out gear.
Sleek and design-forward near LeBreton Flats — handy if Bluesfest or the War Museum is the draw, though a few minutes outside the Market core.
