The cache is in a green, army surplus, ammo container with green 'Official Geocache' stickers on either side. You can easily access it if you are riding a bicycle, or walking. It is located down in the Don Valley, so the TTC does not come very close. You can take the bus to Pape Ave. and O'Connor Dr., and then walk down Beechwood Dr.
If you are driving, you can park near the Toronto Police Dog Services located at the end of Beechwood Dr. The coordinates where you can park are N 43° 41.772 W 79° 21.273 (WGS84). You can also park at the Charles Savriol Conservation Reserve, which is located at Don Mills Rd. and the Don Valley Parkway. The parking lot here can be found at coordinates N 43° 42.225 W 79° 20.011 (WGS84). The cache is approximately 1km from either parking spot.
Follow the paved bicycle path, between the two parking spots, as far as you can. Eventually you will have to leave the bicycle path for rougher terrain.
