William Cubitt and Company had several important commissions including: Covent Garden Market, Euston Station, repairs to Westminster Bridge, extension to National Gallery, etc.
In 1853 Charles Thomas travelled to Canada to work with Worthington Brothers, a well known Toronto-based building contractor that specialized in sandstone construction.
The Cobourg Star for July 7, 1858, reported on the progress being made by Charles Thomas on the main entrance to Victoria Hall (see photo, right), saying: "a vast amount of stone cutting has been accomplished ....
These carvings together with the fine bearded face which forms the keystone of the arch [see photo above] are the work of Mr Thomas, contractor for the stone cutting and they certainly do him very great credit".
The bridge was designed by Thomas Curtis Clarke of Port Hope, Ontario, Canada, who would soon become one of the most celebrated civil engineers in North America.
In the fall of 1867 Charles Thomas was supervising the lifting of rocks on a derrick when the structure collapsed, crushing his left leg.
The deceased gentleman was, during the erection of the Departmental Buildings in this city, Chief Superintendent of Works, under Messrs. Jones, Haycock and Co., and in that capacity earned for himself a high reputation for zeal and integrity.
Mr. Thomas was for sometime Superintendent of Public Works under the Imperial Government of Bermuda, which place he left for Canada about the year 1852; since then and up to the moment of the sad accident resulting in his death, he was engaged as subcontractor in the erection of many important buildings on this continent.
The present national monument at Queenston reared by a grateful people to the memory of the "Gallant Brock," was erected under his supervision, so was the Montreal Bank and Town Hall in Cobourg, the latter considered to be one of the handsomest buildings in the Dominion.
In his death the St. George's Society experience the loss of a most indefatigable member, and with us, they mourn over the sad event which has removed him from our intercourse, and deeply sympathize with his bereaved widow and afflicted family."
