Superior Creek was a stream draining into Lake Ontario in the former village of Mimico, Ontario, Canada.[1] It was approximately 3 kilometers long, with headwaters near the present intersection of Kipling Avenue and The Queensway.[2] The lower reaches of the creek had become polluted, and were buried in a sewer in 1915.[3] In 1954, citizens of Mimico living in newly built houses near the upper reaches complained that the creek flooded, and lobbied to have the creek replaced by storm sewers, and a study was prepared. According to HTO: Toronto's water from Lake Iroquois to lost rivers to low-flow toilets, the creek was buried around 1965.
The creek west of Superior Creek was Jackson Creek, while the creek east of Superior Creek was Mimico Creek.
