With a spectacular outfall similar to the ones at Krueger's Dungeon and the Dundas & Mississauga drains, Giant's Causeway is another Mississauga marvel worth looking at even if it's just for the outfall.
There really isn't too much to say about it except that it's a real sight to behold. The actual 600m creekwater portion of the drain is rather boring and void of interesting features that make a drain worth while.
If it wasn't for the thousands of dollars spent on intricate churn blocks and ramps this drain would be less interesting than a 500mm sidepipe.
