Yes !!

Fascinating to watch a boat go through the hand operated locks. On my bucket list is a leisurely trip on a houseboat from Ottawa to Kingston.

Churchill Falls Hydroelectric Generating Station

Quote:
The Churchill Falls Generating Station is a hydroelectric power station located on the Churchill River in Newfoundland and Labrador. The underground power station can generate 5,428 MW, which makes it the second-largest in Canada, after the Robert-Bourassa generating station...


After years of planning, the project was officially started on July 17, 1967. The machine hall of the power facility at Churchill Falls was hollowed out of solid rock, close to 1,000 ft (300 m) underground. Its final proportions are huge: in height it equals a 15-storey building, its length is three times that of a Canadian football field. When completed, it housed 11 generating units, with a combined capacity of 5,428 MW (7,279,000 hp). Water is contained by a reservoir created not by a single large dam, but by a series of 88 dikes that have a total length of 64 km (40 mi). At the time, the project was the largest civil engineering project ever undertaken in North America.[10]

Once all the dikes were in place, it provided a vast storage area which later became known as Smallwood Reservoir. This reservoir covers 2,200 sq mi (5,700 km2) and provides storage area for more than 1,000,000,000,000 cu ft (2.8×1010 m3) of water.

The drainage area for the Churchill River includes much of western and central Labrador. Ossokmanuan Reservoir which was originally developed as part of the Twin Falls Power System also drains into this system. Churchill River's natural drainage area covers over 23,300 sq mi (60,000 km2). Once Orma and Sail lakes' outlets were diked, it added another 4,400 sq mi (11,000 km2) of drainage for a total of 27,700 sq mi (72,000 km2). This makes the drainage area larger than the Republic of Ireland. Studies showed this drainage area collected 410 mm (16 in) of rainfall plus 391 cm (154 in) of snowfall annually equalling 12.5 cu mi (52 km3) of water per year; more than enough to meet the project's needs. Construction came to fruition on December 6, 1971, when Churchill Falls went into full-time production.

Transcontinental railway?

The CN Tower which was for some thirty years the coolest thing in Canada. It has since been passed by many buildings, but still very impressive.

The Avro Arrow which would have really put Canada on the map for aviation.

The Welland Canal, part of the St. Lawrence Seaway. While parts of it are US, much is Canada.

Queenston-Chippawa Hydroelectric Plant (Sir Adam Beck Hydroelectric Generating Station)
Completes 1925

Queenston-Chippawa Hydro-Electric Development National Historic Site of Canada is located at Queenston, Ontario, at the Niagara Falls. Built between 1917-1925, it was the first large hydro-electric project in the world, and was created by Ontario’s Hydro-Electric Power Commission (HEPC). The HEPC created the project in response to increasing urban and industrial demands for more electrical power in Toronto and southwestern Ontario. The site consists of a very large crescent-shaped site stretching approximately 22 kilometres from the mouth of the Welland River where it meets the Niagara River, through the city of Niagara Falls to the hydro-electric generating station situated on the Niagara River between the Whirlpool and Queenston. Official recognition refers to the entire development associated with the power project from its intake at the junction of the Welland River and Niagara River to the outtake at the Sir Adam Beck No. 1 Generating Station near Queenston including the gatehouse, penstocks, and powerhouse on their footprints.

HERITAGE VALUE

Queenston-Chippawa Hydro-Electric Development was designated a national historic site of Canada in 1990 because:
- it claimed to be the first true hydro-electric mega-project in the world
- the design of the Queenston-Chippawa installation presented unique problems and required construction equipment, power conversion units, and a power canal of a size not seen prior to their use at Queenston-Chippawa.



Also at the top of the Horseshoe Falls The Toronto Hydro Power Plant built in 1906, a much smaller but historically important project.

Pont Victoria, Montreal. At the time it was built, it was the longest bridge in the world:

No matter what people think the Olympic Stadium got to be there. Tallest inclined tower in the world still to this day.

Still one of the first Stadium to had a retractable roof. However, the engineering of it was more complex than anything ever built.

Fairly certain this is now the worlds tallest inclined tower

The Lethbridge viaduct.
1909 - 1,624m long
Longest and highest trestle and there are no weight or length restrictions so toughest too. The CP engineer responsible also was responsible for the Spiral Tunnels.

Not human engineering but...

The world's largest beaver damn in Wood Buffalo National Park AB. 850m long.

Not as long, but built 1906-1908 in Quebec City's suburb of Cap-Rouge.
