Possibly interesting.
A Daniel Staveley born 1894 in Burnley, England, enrolled in the Canadian Expeditionary Force (CEF) in 1917:

His next of kin is his mother Annie in Montreal.
In 1901, Daniel was in Burnley with parents John and Hannah, and
brother Charlie aged 13 (born about 1888).
That is the Charles born in 1887 in Burnley that I mentioned way back.
(Ann and Hannah were often interchangeable.)
In 1911 the parents and other children are in Burnley and Charles is also there separately.
However, Charles is married by 1911.
He is a cotton mill worker.
D Staveley born 1893 travelled to Monteal in 1912.
The other passengers match the family from Burnley:
H female 1968 (mother Hannah)
JT male 1866 (father John)
A female 1896
JT male 1903
Wm male 1889
That Charlie just does look a lot like the one in the passenger record lilybell posted:
British Reservists
Staveley Charles
3Rd E Lancs
Age 25
Country of Last Permanent Residence Canada
Country of Intended Future Permanent Residence England
This passenger record puts his DOB as 1889.
The military record I mentioned previously indicates he was in the Territorial Force.
That Charles's wife, Florence Maude Smith, was almost 10 years older than him.
And there are no children born to them after 1911 (assuming Smith was her birth name - no Staveley births in Burnley at all 1911-1918).
Maybe that marriage did not last and he joined his family in Canada.
There is no death to match him in England.
There is also no death for a Florence M Staveley. Nor do I see an identifiable remarriage for her under that name ... but she could have remarried under her birth name ...
