I was doing some local history research and trying to find out more about the history of Ottawa's political borders and got the whole story
. When the city first became a municipality in 1850, it was carved out of the Township of Nepean, with it's border at the Rideau River to the east, a line corresponding to what is now Gladstone Avenue & Mann Avenue to the south, and Booth Street to the west (except north of Albert, where the city extended a little further to the west to include all of Lebreton Flats). So basically, just present-day Lowertown, the northern two-thirds of Sandy Hill and Centretown, Lebreton, and Chinatown. These were unchanged for nearly 40 years and were Ottawa's borders at the time of Confederation.
Ottawa's borders were expanded in 4 waves. One in 1887-1889, another in 1907-1910, another in 1950, and finally in 2001.
The first of these waves, in 1887-1889, brought New Edinburgh, the Glebe, and Little Italy into city limits. At this point, the northeastern border of the City of Ottawa reached its final pre-2001 form. The southern border became the Rideau Canal and the western border became the railway line that is now Line 2.
Around this time period, a bunch of villages sprouted up just past the city's borders. Old Ottawa East (then just called Ottawa East), Hintonburg, Mechanicsville, and Westboro were founded in the Township of Nepean, while Janeville, Clarkstown, Clandeboye, and Rockcliffe Park were founded in the Township of Gloucester just east of Ottawa's border. Of these, Ottawa East and Hintonburg became independent municipalities while the remainder remained within Nepean and Gloucester.
So the situation in the 1890s and into the first years of the 20th century was one of the City of Ottawa immediately bordered by several village suburbs, the largest of which were independent municipalities.
A major amalgamation (the second wave of expansion of the city limits) occurred in 1907. The municipalities of Ottawa East and Hintonburg were annexed to the City of Ottawa; at the same time, more bits of Nepean Township were annexed as well, covering Mechanicsville, what is now Old Ottawa South and the Civic Hospital area. A small triangle around what is now Westgate was added a bit later, in 1909. In the east however, none of the villages were added to the city at this time; the three villages of Janeville, Clarkstown, Clandeboye were merged to form the independent municipality of Eastview (renamed Vanier in 1966) while Rockcliffe Park remianed entirely separate, eventually separating from Gloucester to form its own municipality in 1926.
This map below (drawn by me) thus shows Ottawa's municipal borders as they were during both world wars.
This is the City of Ottawa as its border existed from 1909 to 1948. In orange, I outlined the city's original 1850 borders, and in red, marked the limits of the 1889 annexation. The 1909-1948 City limits roughly incorporated all of what could be called the "urban" part of the city, minus Westboro and Vanier (then called Eastview) which existed as developed communities but were independent. It's interesting to note that what is now Tunney's Pasture and Carleton University were located just outside the city's limits.
It's also interesting that the western limit of the Village of Hintonburg that the city annexed in 1907 was at Western Avenue (which is probably how that street got its name--it was the city's western border!); it did not extend to Island Park, which is what people typically think of as the Hintonburg-Westboro border. This actually explains what I call "the great gap"--the sort of dead area along Richmond from about the Superstore to about Western Avenue that isn't really a part of either Westboro's or Hintonburg's urban form--Hintonburg didn't actually extend past Western Ave to directly meet Westboro.
By the time World War II happened the city had filled up all the land inside the borders and needed expansion territory. With the rapid population growth and the beginning of the baby boom and the home ownership boom, new land was needed. In 1948, this triggered a major review of municipal governance in the area. A small area consisting of the northern half of what is now Carlington (roughly north of Shillington Avenue from Merivale to fisher) was immediately annexed to Ottawa while this review was underway. The first proposal, published in May 1948, would have had Ottawa annex all of Gloucester, Nepean, Vanier (then Eastview), and Rockcliffe Park; this would have brought into the city all of what is now the urban area minus Kanata-Stittsville and eastern Orleans. Here's an online archived copy of the Citizen from May 17th, 1948 in which the proposal was published (scroll to page 13) -

This was rejected as too extensive. Interestingly enough, judging by the newspaper coverage of all this, it wasn't the outlying residents worried about losing autonomy (like in 2001) that caused the complaints; it was actually residents of the City worried about the City having to spend too much money to expand city services out to the newly annexed areas. People in the outlying areas (especially Westboro and Bells Corners) were actually excited about the idea of being amalgamated and getting all the fancy city services.
Instead, it was decided that Ottawa would annex large chunks of Nepean and Gloucester (thus bringing Westboro into the city) and Eastview and Rockcliffe would remain independent. This came into force on January 1st, 1950, thus expanding Ottawa's border to its final form pre-2001 amalgamation. At this time, Ottawa thus had a large amount of rural land within its borders which was rapidly developed as suburbs in the 1950s and 1960s. However, Ottawa filled to these borders soon enough, and with the rump areas of Nepean and Gloucester by then seeing rapid development too, they made the decision to form the two-tier Ottawa-Carleton government in 1969.
(Aside: one fascinating thing I discovered when poking around all of those newspaper articles from the late 1940s was how different foreign affairs coverage was then. It was way more focused on Britain and the British Empire than it was on the United States--all kinds of details about Atlee's reforms and the situations in dissolving British colonies like India and Palestine were on the front pages but very little about anything happening in the USA).
