John Redpath emigrates to Canada from Scotland and walks from Quebec City to Montreal to get his first job. 

John establishes his building business, works on several major Montreal landmark buildings:

The Montreal General Hospital

The Lachine Canal

Notre Dame Cathedral

The Theatre Royal

The Bank of Montreal

The Montreal Water Works

The National Schoolhouse

John develops his financial and mercantile investment portfolio and takes up directorships within several companies, as well as extending his philanthropic efforts to aid the poorer citizens of Montreal. 

The "Canada Sugar Refinery" is build in Montreal on the banks of the Lachine Canal. 

The Canada Sugar Refinery opens for business August 12, 1854. 

The C.S.R. becomes "John Redpath and Son, Canada Sugar Refinery".

John Redpath dies on March 5, 1869, Peter Redpath (John's eldest son) becomes President. 

With the introduction of new production technologies (that reduced the production cycle from 10 to 12 days down to 18 to 20 hours), the C.S.R. is the first sugar manufacturer to introduce boxes and barrels of loose granular sugar to the Canadian market, replacing the earlier retail product of hard sugar cones. 

The "John Redpath and Son, Canada Sugar Refinery" becomes incorporated as a public company as "The Canadian Sugar Refining Company Ltd." 

The John Redpath signature, used formally as the company logo for the previous 15 years, is officially registered as the company's trademark. Peter Redpath retires and George A. Drummund becomes President. 

"Redpath" introduces tabletop (1lb and 2lb) ready-packaged sugar to the Canadian market, the first company in Canada to do so. Women join the plant workforce in the new packaging department. 

Canada's sugar industry is effectively placed under Federal Government control as part of Canada's wartime economy during the "Great War". 

The cane-based "Canada Sugar refining Company Ltd." merges with a former competitor, the beet sugar processor, the "Dominion Sugar Co. Ltd." to become "Canada and Dominion Sugar Co. Ltd".

The entire Canadian sugar industry comes under Federal Government control for the duration of World War II. 

 Tate & Lyle Technical Services of England is hired for the construction of a new factory in Toronto.

Tate & Lyle PLC acquires a minority shareholding. 

The Toronto location begins production on May 21, 1959. The official opening, by her Majesty Queen Elizabeth took place on June 29, 1959. Tate & Lyle PLC becomes the majority shareholder on December 6, 1959. 

Following significant diversification into non-sugar business, the company restructures itself to form a holding company, "Redpath Industries Ltd." With "Redpath Sugars Ltd." as its main component.

The Redpath Sugar Museum opens for public visitation and the provision of educational tours and programming. 

Production at the original Montreal refinery ends. Warehousing and distribution continues from the Lachine canal site until 1985, when a new distribution facility is opened. 

Tate & Lyle PLC divests itself of the non-sugar elements of RIL and acquires all outstanding minority shareholdings within Redpath, becoming sole owner. 

The Redpath Toronto refinery undergoes a major expansion and modernization of its production systems, almost doubling its output potential. 

Tate & Lyle PLC sells Redpath Sugars to ASR sugar company group.

The Redpath Toronto refinery installs a new bulk raw sugar crane on its dock that has the capability of unloading more than double the volume of sugar that the original two cranes could in an equal length of time.
