This is my first attempt at a puzzle cache.
THE CACHE IS NOT AT THE POSTED COORDINATES.
It can be found by coming up with the solution to the following:
Lanark Gardens, Hallmark Apts., Rideau Towers, Edgewood Estates, 9 Mandalay Dr, Aura Tower, The Marquis Village, Blair House.
There may be multiple options , but there is just one correct answer.
CONGRATS TO JB. ON THE FIRST TO FIND!!!
