Canada’s London had its Great Fire in 1845. This destroyed one-fifth of the downtown’s buildings including St. Paul’s Cathedral (rebuilt the following year). Industrial modernization was much in evidence with the introduction of gas streetlights, new rail connections and telegraph service extending into Quebec. A mayor and town council structure came into effect, and, in 1855, London was incorporated as a city with seven wards. Legacies of these 19th century years range from The London Free Press newspaper and an urban police force to landmarks such as St. Peter’s Cathedral and Grosvenor Lodge.
