In partnership with the Ports Toronto, we attempt to pick up as much surface debris within our marinas and several waterfront slips such as York, Peter and Portland as possible. Surface debris such as cups, wrappers, "weed", waste, feathers and small bits of driftwood may accumulate depending on rain quantities which flush out river basins, weather and wind direction. Smaller sized debris located in corners or hard to get at locations is picked up manually by hand by our Marine Crew aboard our small work boat. Larger debris such as logs, branches or other navigational hazards found within the harbour or waterfront slips are picked by the Ports Toronto using the William Rest and a barge. Visit The Ports Toronto Harbour Hot Line for details.
As of March 2012 our access to orange City of Toronto owned slip cleaning machines was terminated. Since all debris must be removed using small tools such as pitch forks and nets. You can imagine this is difficult, wet, hot hard work and is vastly slower than using the machines. Once collected debris is transferred by hand to a small barge located at the east end of the harbour in preparation for disposal.

Aquatic plants are an important element of the marine environment. They provide habitat for numerous aquatic species and help retain water quality for starters. Excessive plant growth at the surface in marinas is a challenge in many boating regions especially in July and August as water warmth expedites growth. Eventually plants reach the surface and become the nuisance we all see. Zebra Mussels complicate things further by filtering particulates which make the water clearer allowing a greater amount of sunlight penetration. This also promotes plant growth. In addition, other locations around the Inner Harbour and Lake Ontario cut plants which can form large patches that can drift into a marina. Marina Quay West is not the only location with a "weed" problem. In fact, many other locations have it much worse.
Removing surface plant growth – or "weeds" as many call them – is a cumbersome, time consuming, expensive, wet and heavy job. It potentially costs tens of thousands of dollars annually to remove weed from Marina Quay West. We make efforts to remove some growth by pushing, towing and directing weed into channels so crews can pick some of it it up. You can imagine wet weed is heavy, so lifting it by hand is hot, slimy, wet and dirty work. Those of you that attempted to partially clear your own slip know this. Patches may be contaminated with hazardous waste such as needles, dead animals and other unfriendly smelly items. Both our Marine Crew (Marine Services Dept.) and Marina Staff (Marine Operations Dept.) work hard to provide some relief but must work safely keeping the above in mind. Despite, it tends to be a loosing battle since we are unable to remove massive quantities of heavy growth quickly. Plants continue to seed and grow rapidly throughout a hot summer.
In summer 2011 our team removed approximately 30,000 pounds of debris from Marina Quay West in August alone! Are you surprised? Many people are. When you arrive at the marina after work or on the weekend it may not look any different. We likely have removed a large amount of weed. When surface growth is removed it may be displaced by growth rising to the top, drifting into a cleared area or simply spread out. It may not look like anything has been done.
Weed reaches the surface in 2011.
In summer 2012 plant growth peaked much earlier. We speculate this was due to record setting temperatures starting in March. The assumption is that plant life cycles started and therefore ended much earlier. Plants likely dropped to the bottom at the end of their lifecycle in late July or perhaps they did not flourish in the abnormally warm water. As a result clean up was much easier. However, once plants drop to bottom they can reseed causing greater issue in following years.
In summer 2013 and 2014 the weed problem seemed to peak in late July but was short lived. This was likely due to the cooler wet summer, less sunlight and highly as a result of somewhat higher water levels. Come August there were only a few small pockets of concentrated weed growth. Much of the weed did not reach the surface.
Following a record cold and snowy winter in 2014, a standard end of July and August peak was likely. With snow and ice accumulations water levels were higher than in 2013. However, the plant growth amount and accumulation was less based on temperatures and the number of sunny days we had May to July. As suspected the ice storm in December 2013 caused much damage to trees within the Don River Valley and was likely cause for large amounts of tree and shrub debris found in the Harbour in spring 2014. This also likely caused a TPA boom breakage in late June which initiated a substantial clean up effort prior to the July 1st long weekend.
In the summer of 2015 we saw limited weed growth and surface patches. Some manual cleaning of weeds was required in certain slips and some patches within channels but nothing like years past. This decrease may have been a result of cooler temperatures and perhaps our reluctance to cut weed preventing reseeding over the past few summers.
With great weather comes weed. A stellar 2016 summer again caused areas of growth due to warm water and high hours of sunlight. This growth was enough to cause issues for some smaller boats. We attempted to remove as much weed as possible with use of a rented machine and recommend to those affected to move to alternate slips that did not contain growth.
Since 2016 various conditions have resulted. Record high Lake Ontario water levels in 2017 and 2019 may have contributed to less surface weed due to water heights.
We hope this helps you see things differently and that dealing with this nuisance growth is a surmountable task. Harbourfront Centre at least had some resources to improve this challenging situation. We wish for hot summers but this is an unfortunate downside.
We will have to keep working on innovative ways to maintain the aquatic ecosystem but improve the surface situation for your boating pleasure. If you face arrival and departure challenges due to the amount of plant growth in your slip and around your hull please inform the marina office staff. Staff may be able to manually clear weed from your slip or assign you a temporary alternate slip so that we can attempt to clean your slip. You are reminded and responsible for making sure that all motor or cooling system intakes on your boat are kept weed and debris free!
Thank you for your understanding and cooperation. We hope that you continue to enjoy the waterfront despite this mostly natural inconvenience.
