Dover was elected to council the same year as the City’s youngest mayor (to date) – Don Mackay, who had been an alderman since 1945. Dover was elected on the 13th count in what was called a “long, drawn-out struggle for the eight vacant seats on city council”. Ballot counting and re-counting occurred through election night (November 23) and continued until early afternoon the following day, when the final candidates were officially declared elected. Dover joined fellow woman Alderman Rose Wilkinson on council. The women were supported by opposing slates – Dover by the C.G.A, and Wilkinson now running as an Independent.
Early in her council tenure Dover got involved in a contentious issue that resonates today – that of compulsory vaccination. At a council meeting in April 1950 Dover suggested vaccinations be made compulsory for Calgarians. This prompted backlash, particularly from the Alberta Anti-Vivisection and Humane Education Society – it was reported that “the mayor, aldermen and school board … were deluged with pamphlets, letters and resolutions” from the Society. The main resolution “asked Mayor D. H. Mackay to get full guarantee of the safety and effectiveness of vaccines, serums and anti-toxins from manufacturers, doctors and so on”, and demanded “that no further expenditures of Calgary taxpayers’ money shall be wasted on purchases of these poisonous products, on their administration by doctors or nurses, or on falsely publicizing them as preventatives and cures for diseases”.
In response, a Calgary Herald editorial pointed out that while the anti-vivisectionists “argue … that anti-smallpox vaccination is useless, they do not explain how smallpox has been practically stamped out in most civilized countries since vaccination became a universal practise”. The author of the letter referred to the anti-vaccination campaign as having “the appearance of a fanatical and dangerous agitation which ought to be explicitly and publicly condemned”. Regardless of her advocacy and campaigning on the matter, Dover’s push for compulsory vaccination was defeated and the issue would not arise again during her tenure on council.
Dover was re-elected again without much fanfare or issue on November 22, 1951. In June of 1953 Dover was one of three candidates to represent the federal Liberals in the Calgary South constituency. She was defeated by local barrister Edward J McCormick, whose nomination she initially contested.
Possibly wounded by the federal loss, Dover chose not to seek a third consecutive term on Calgary council in 1953. She was nominated again as a Liberal candidate in the 1955 Alberta general election and campaigned hard to be elected but lost handily once again. Dover suffered another blow the summer of 1955 when her husband passed away in August.
Dover kept busy in community activities through the 1950s. She also continued to advocate for good and forward-looking city building, including the preservation of buildings of historical interest.
On September 21 Dover made her aspirations to return to politics official as she was chosen as a one of a slate of six aldermanic candidates to represent the United Citizens’ Association (formally replacing the old Civic Government Association). She was advertised as “a former Alderman, a perceptive critic of civic affairs, and a staunch individualist” who was “one of the first to make public her views on all issues, favours more local industry, better liquor laws, more beautiful buildings, and the Canadian Flag”. Dover’s campaign included a position “wholeheartedly in favour” of introducing fluoridation of the public water system.
Dover was elected on the seventh count on October 17, 1956. She was the only woman in the aldermanic race, joining fellow woman Alderman Isabella Stevens who was already on council (elected on an alternating term). An article from the October 18 Calgary Herald quoted Dover as being “terribly thrilled about being elected”. When questioned about women in politics, Dover said she believed more women should run for public office. “Mind you, I’m not a violent feminist. But we women have our place. I think women have a knack and a patience for detail that men often lack. Women take a lot more trouble to find out the answers to problems and when they make a decision they have a feeling of satisfaction, knowing they’ve put their best into it. It’s the way women’s minds work.”
Dover was an active and gregarious Alderman for the next four years on council (being elected once again in 1958). She was markedly interested in city building and urban planning issues – many that continue to resonate in Calgary today. She was an ardent supporter of refurbishing and repurposing old buildings rather than tearing them down. This included the Bruce Robinson building, an old warehouse structure located on 9th Avenue and 4th Street that Dover first tried to save by proposing investment and alternate use (the building was demolished in 1958).
