In 1964 when Willie was applying for his old age pension he contacted The Loyal True Blue & Orange home in Richmond Hill, Ontario to try and establish his proof of age. 
According to their records:-
Registered as -  William Woods.
Date of Birth -  Jan 1 1901.
Place of Birth -  Wales.
Date of Admission to the Home – Sept 19 1907.
Former Residence – Nipigon, Ontario.
Father – Charles Woods, Nipigon, Ontario
Mother – Deceased.
Date of Discharge – Mar 19 1910.
Adopted by – Mr. Henry Thistlethwaite, Norwood, Ontario.
I may have found a possible death for the mother but it doesn't quite fit the above data:
Name: Edith Wood 
Died: 29 Oct 1907 
Location: York  
Gender: Female  
Estimated Birth Year: abt 1884  
Birth Location: England   
Address:  612 Wellington Ave  (Very Poor Image-address may be incorrect?)
Occupation:  Housewife
Informant:  Charles Wood
Cause:  Mitral Stenosis-Edema Lungs - 10 Days
If this is correct, the children were given up prior to their mothers death?  There is a chance that Edith became ill and the Doctors told Charles that she would not survive.  Preparing for the worst, he may have arranged their care prior to her death.  This is all speculation though?

Update: It looks like the above is probably incorrect.  I found a child born linked to the death:
William Charles Wood 
Birth: 30 Sep 1907 
Gender: Male  
County: York  
Father: Charles George A Wood 
Mother: Edith Underhin  (Andrews crossed out)
Address:  612 Wellington Ave
Occupation:  Labourer
***** I doub't that Charles would have named two children William.
