The Château Laurier in Ottawa. Completed in 1912 by the Grand Trunk Railway, along with Union Station across the street, it was built on the southern end of Major's Hill Park which has essentially been a city (now Federal) park since Colonel John By founded Bytown in 1826. Thanks to the support of Wilfrid Laurier, a parcel of the park was allowed to be sold to GTR.
The opening was delayed by a few months when the President of the GTR, Charles Melville Hayes, perished in the Titanic in April 1912.
A pedestrian tunnel connecting the hotel and station still exist and a rail tunnel was built between the hotel and Rideau Canal to accommodate the Canadian Pacific Railway right of way and Hull Electric Railway's terminus station. That tunnel served as the Canadian Museum of Photography for a few years before it was converted to committee rooms by the Harper Government. A bicycle rental business occupies a part of the tunnel, including the Hull Electric Railway turn-around tunnel.
The hotel an east wing was added in1929 and a parking garage at north end in 1969, though it was demolished last spring.
To this day, the Château holds a place of honour in the heart of Ottawa at the top of the Canal's Entrance Bay locks, between Parliament Hill and the Byward Market. Through old Union's days as a grand railway station were brought to an end in 1966, it served as a Government Conference Centre until just a few years ago when it was closed for renovation and a new vocation as the Upper House of Parliament during renovations to the Centre Block.
Several expansions have been proposed since the 2016 for the site of the parking garage at the Major's Hill Park side of the hotel. I've posted the various renditions at the end of this post. The last one was approved by City Council on the condition the architect goes back to the drawing board (try to wrap your heads around that one). The City wants more depth variation to the façades, more limestone and a re-drawn roof to better emulate the peaks of the existing.
Here's the Château Laurier as it appeared on opening day on June 1, 1912.

Here are some similar views of the 4* versions formally presented to the public.
*Note that the first and second version we pretty much the same, so they both be defined by the first picture.
