It was typical of the time period for many newly minted master silversmiths to branch out and start their own workshops. Whereas many of the apprentices of Georg Jensen had set up their own shops within Copenhagen, in 1929 Carl Poul Petersen left Denmark with his wife, Inger Jensen, and emigrated to Canada.

Once he arrived, he was hired immediately by Henry Birks and Son Ltd. , a silver company specializing older styles and trends, as their resident goldsmith. Birks had specialized primarily in older styles and fashions such as Rococo and Neo-classical, to which Petersen's Jensen-like style sharply contrasted. 

In 1937, Carl Poul Petersen moved on from Birks to set up his own workshop, however, this was cut brief by the lack of silver brought on by the World War. It was during this interim that he contributed to Allied wartime efforts manufacturing brass and aluminum parts for the Mosquito fighter planes. Once the war had ended, however, in 1944, he resumed his work in silver, opening up a shop in Montreal where he was assisted by his three sons, Arno, Ole, and John Paul. There, they made very fine, handmade silver. Much like Georg Jensen, he was quite extensive in the breadth of pieces he produced, including 11 flatware patterns, a variety of hollowware pieces, including tea services, candleholders, as well as a full line of jewelry. His fine pieces are scarce and desirable today.
