While living in Montreal, he had the opportunity to meet, and become acquainted with, many of the leading artists of the day including Homer Watson, William Brymner, Maurice Cullen, and later, members of the Group of Seven, in particular A.Y. Jackson.
During this time, he also acted as the Montreal correspondent for the leading English art journal, The Studio.
As an art critic he wrote in defence of the Group of Seven at a time when most other critics were attacking their work.
Around 1920, he left his position at the Mining Institute in Montreal to take up the post of Secretary-Treasurer of the BC Division in Vancouver.
In 1926, he opened a gallery on Robson Street with fellow photographer John Vanderpant.
Although their association was short-lived, the gallery continued and was a centre for music, poetry, and painting.
Among the artists showcased were members of the Group of Seven.
After his retirement from the mining industry in 1941, he himself began to paint, his works being exhibited in Montreal and Vancouver.

His work was widely exhibited and he was eventually elected an Honorary Fellow of the Royal Photographic Society.
For many years, he also fostered a keen interest in the arts, helping to found a small art club in Victoria and frequently contributing articles on the Canadian art scene to the Canadian Magazine and other periodicals.

Harold Mortimer-Lamb died in Burnaby, BC on 25 October 1970.
His daughter was Molly Bobak, well-known Canadian artist.
