Hi Dollylee & all...
There is a birth ( unlisted source) on the IGI - for an Emma Hannah Wood to Amos E Wood and Mary Anne Coll in Oxford Ontario...in 1869....
and there doesn't seem to be a marriage for that couple in England...
However as you've noted, no other Charles Wood come up under head of household as Amos...(no Emmas either-sheesh) ( in 1881)
This doesn't take away from your find, though...re: Hydro work, as that makes lots of sense.... & you never know, Charles might still have been born Canada, but married and had children in Wales
I do perhaps see Amos E. ( Woods) in 1901, widowed with only parents (WENTWORTH & BRANT N.) but no sign of same in 1881...

Ahhhhh, but then would we be having all this fun?
