I then went on to completely and utterly forget about this hide - a waypoint on my GPS that never got looked at again... until I was driving by late this summer and had an "AH HA" moment! I managed to get back to this location just recently to see if my container had held up over this time. I was utterly disappointed at the amount of trash that has been left or blown into this location. 
I tried to figure out how to still use this location and the best I could do was make this a puzzle cache about garbage!!
I have provided a link to the Niagara Region Waste Management site - that will help you for most of the questions!
So here we go!
Assume that we are only looking for the final three numbers of the North and West coordinates. N 43 06.ABC W 079 05.DEF
A - look for the missing number (X) to contact Waste Management “905-35X-4141”
B - look for the missing number (X) in the max height limitation for alternate blue box container – “X1 cm”
C - number of people in the alternative rock band GARBAGE 
D - look for the missing number (X) in the phone number for Large Item/Appliance Collection for Niagara Falls "1-833-621-0X26"
E - look for the missing number (X) in the maximum weight in pounds for acceptable Grey Box Alternate Containers – “X0 lbs”
F - look for the missing number for a single family home garbage tag costs in Niagara? $X.50
You are looking for a test tube container. Good luck!
