In 2031 the city of Hamilton was destroyed by ballistic missile. The city began to rebuild however due to the scale of the damage at the economic collapse of 2035 the city was never rebuilt and all the former residence and survived had migrated to other parts of Canada. In 2039 the former site of the city of Hamilton was purchased by the agricultural company green tech. This company converted the former site of the city into a large hydroponic agricultural facility that provided fruits and vegetables for Canada, and for export. This helped improve the economy of Canada. Eventually this facility was acquired by the Republic of new Toronto which later became known as the Republic of Ontario. This facility was the most advanced hydroponic facility in North America and really helped foster the hydroponic food movement of the of the late 21st century which helped the agricultural crisis that the world was facing during a century due to intense irreversible climate change.
