From what Rosie and Pennines have found above, looks like he left her in 1926, going by that shipping manifest that Rosie has posted details on.
The family remained in Carnwath Road didn't they. Valuation Rolls only go up to 1940 currently on SP (they are slowing adding years online).
Not sure how you would find further details of his life in Canada. Maybe start a new thread on the Canadian Board here on RC and add a link to this thread so that others can see what Pennines and Rosie have already found.
Rosie has posted his death details too so again you have definite info and records to work with.
