Mills Family of Bruce Mines, Canada

I am looking for my dad's relatives in Canada.  He was James Ernest Mills 1927-1990; his parents were John Wesley Mills 1904-1945 & Elsie Harrison 1902-1989.  The family was from Bruce Mines-my Grandfather, John, worked on trains & the family immigrated to San Francisco CA where my dad was born.  I have located my Grandmother's youngest brother.  I would like to find cousins.
