Table schema:
CREATE TABLE table_name_96 (area__km_2__ INTEGER, rank VARCHAR, municipality VARCHAR, province VARCHAR, status VARCHAR)

Question: What is the highest Area (KM 2) for the Province of Ontario, that has the Status of Town, a Municipality of Minto, and a Rank that's smaller than 84?
SQL: SELECT MAX(area__km_2__) FROM table_name_96 WHERE province = "ontario" AND status = "town" AND municipality = "minto" AND rank < 84
