Canmore Park is nestled in a residential neighbourhood in Highland Creek. It's a lovely place to stroll through, and you'll almost always see kids playing on the grass, especially on cool summer evenings. The cache is a small pill bottle wrapped in black tape. Please replace it in the exact orientatation you found it; this will make it less visible to muggles on the sidewalk. Also, make sure to stay stealthy while retrieving it, especially during the school year, as there are two schools bordering the east and west ends of the park.
Happy hunting!
