As usual with listings like this, I went to the Toronto city directories to indulge my morbid curiosity: how many more birthdays did she get to have? The answer appears to be about three. The 1929 directory lists Margaret Sintzenich at 552 Balliol and she appears in the 1932 directory at that address. (In the latter, she is listed as the widow of Maurice.) She does not appear in the 1933 directory.
552 Balliol Street appears to be a nice semi-detached house in the Davisville neighbourhood. It looks like it hasn't changed much since Ms. Sintzenich celebrated her 90th birthday there.
