Toronto's man-made peninsula, the Leslie Street Spit, is still growing, and will be for the next few decades to come as dredged material from the city's harbour continues to be deposited along its shoreline. The artificial peninsula extends five kilometres into Lake Ontario and is over 500 hectares in size. Once removed from the channel bed, the mix of debris and sediment is transported to the Leslie Street Spit for "proper containment" in a "cell" or Confined Disposal Facility (CDF). "Cell 1 has been very successful to date with reports of significantly increased fish populations and the return of pike and muskie to the harbour," PortsToronto notes on its website. With the completion of Cell 2 capping, the TRCA notes that it is no longer accepting fill (including concrete, bricks, or blocks) at the Leslie Street Spit.
