I did a little searching on the internet to find out more about Tuck Creek and came across this group:
Field and Stream Rescue Team. A non-profit organization focused on cleaning and rehabilitating the areas left unattended within Halton Region's city limits.
This group reminded me of Geacaching CITO, so have a look at the FSRT website and the upcoming projects.
This group roots around in the same places cachers do, this can be an opportunity to find some nearby caches, place some new ones and do some CITO.
