3-5 Cameron Street were demolished in late February 2021.

3-5 Cameron Street are 2, Second Empire Worker's Cottages that date to 1885. Cameron Street was laid out in the 1870s and was first built on in 1876. The street is named after the Hon. John Hillyard Cameron (1817-1876) - who was a Ontario-based businessman, lawyer, and politician that owned the lands the street is now on.  During World War I, the Royal Canadian Ordnance Corps Warehouse was located immediately north of this row of houses (at 15 Cameron Street). This later became the headquarters of the post-war Unemployment Insurance Commission Office. 

The original 19th century and early 20th century Cameron Street streetscape was virtually obliterated in the late 1960s during the construction of the housing projects now synonymous with the Alexandra Park neighbourhood. In 1899, there were 62 houses on Cameron Street. By 1924 this number had reduced to 58. Subsequently, the number of houses had reduced to 43 houses in 1967; 15 houses by 1968; and 6 houses by 1969. These remaining houses were mostly in the row of Second Empire Workers Cottages of which 3-5 Cameron Street are the last surviving of. The rest of this row - including 1 and 7, 9, and 11 Cameron Street - were expropriated and demolished in the 1970s to allow for the creation of a driveway and parking area for a nearby Canada Post depot.  Only a few years later - circa. 1980 - the lowrise apartment building was constructed on adjacent 7 Cameron Street.
