They also provide vital habitat for native species. PHASE 02: WATERWAY DEGRADATION 1793 1884 Toronto’s booming population leads to rampant pollution of Garrison Creek, as well as its use as a recreation site. Several bridges are built across it, while the slopes are logged for housing. The stench from the area grows. 1850 1900 1950 2000 1800 1750 1700 PHASE 03: SEWER 1884 Present Over the course of 35 years, the city converts Garrison Creek to a large, enclosed sewer running along the Creek’s old path. The combined sewer is still in heavy use today, and the sound of rushing water can be heard at times.
