Mason was born in Chesterfield, England, and was schooled until age 13, whereupon she went into service in Bradford with a family who ran an off-licence. She later married John Mason, a miner, in 1914, after which they lived together at Upton, West Yorkshire until John died in 1962. Mason spent time with John at Butlins in Filey and Skegness where she worked making sandwiches. Ada had an aunt who lived to 104.
Mason outlived all five of her children and attributed her long life to eating bread dripping with salt every day, along with clean living. Mason lived independently until the age of 110, after which she moved into a nursing home. Upon her death, then-110-year-old Florrie Baldwin became the oldest living person in the UK.
