Please find details here:


Pre-qualification information, submitted on the attached pre-qualification form with supporting material (e.g. company resume, key employee resume, company resources, comparable project brochures, etc.) will be received at the Kahnawà:ke Environment Protection Office (KEPO) in Kahnawà:ke, QC. Please provide references for past projects completed for either the Private or Public Sector (e.g. Conservation Authorities, Municipalities, Provincial/Federal Ministries, etc.).

The purpose of this Request for Pre-Qualification (RFPQ) is to identify up to a maximum of eight (8) qualified general contractors that will be invited to submit tenders for the Recreation Bay Restoration Project (herein ‘the Project’).


The objective of the proposed project is to improve the shoreline of Recreation Bay for the Kahnawà:ke community, by restoring wildlife habitat and enhancing access to the bay for the community. The project is located in Kahnawà:ke, QC. The unnatural shoreline on both sides of Recreation Bay forms a narrow strip of about 10 to 30 m wide between the water and an existing bike path. Bank slopes on both sides were constructed with excavated rock and clay from the construction of the St. Lawrence Seaway channel. The proposals for shoreline restoration are summarized as the creation of two natural zones, the first being a turtle nesting ground and the second a pond and marsh.

The first natural zone is located at the western end of Tekakwitha Island, between the wetland and the marina. The natural zone will consist of a marsh, a turtle nesting ground, a scrubland (plant community composed mostly of shrubs without distinction of the genus or species) and a scrubland with scattered trees.

The second natural zone is located in the center of Tekakwitha Island, along its south shore, just east of the wetland. The main goal of this natural zone consists of creating four types of wetland, namely marsh, wet meadow, shrub swamp, and a linear pond that will be located where the ancient channel flowed between two original islands prior to the construction of the navigation channel.


The work includes, but is not necessarily limited to, the supply of labour, material, supervision and equipment to perform the following tasks:

•Build a marsh of about 735 m2

•Build a turtle nesting ground

•Install rock shelters in the scrubland

•Build a wetland (linear pond, marsh, wet meadow and shrub swamp) of about 16,510 m2

•Build a terrestrial habitat of 6,590 m2 between the wetland and the original ground

•Install live shade made of long willow cuttings

•Remove two populations of European reed (Phragmites)

•Seeding and planting

Note: The detailed design drawings will be supplied to the pre-qualified bidders who are invited to bid on the Request for Tender for this contract upon successful completion of this Request for Pre-Qualification (RFPQ) process.

The construction of the Seaway severed our physical access to the river and caused damage to our cultural connection to the waters, and the foods that sustained us for generations.  The seaway also created an artificial environment and disturbed the natural balance that had formed along the banks of the St. Lawrence. The Kahnawà:ke Environment Protection Office has been studying the Recreation Bay for many years in order to understand the environment and come up with a long-term solution to the environmental challenges.

The low flows and wide area of the bay have been causing sediment carried from faster waters upstream to drop in the bay, slowly filling it up. The sediments coming from the Chateauguay River are very high in nutrients because of upstream agriculture and therefore aquatic plant growth is favoured and occurs very quickly. The challenge for KEPO is to develop a solution that will prevent the loss of the Recreation Bay and that will be sustainable over the long-term. KEPO has been working with experts to assess and design solutions that will meet this challenge.


The following studies have been carried out in and around the Recreation Bay. These studies can be viewed in their entirety at our office. Here is a summary:

2008: Shoreline Characterization Study – Groupe Hémisphères

This study was the first step in characterizing the health of the bay and the Kahnawà:ke shoreline more generally. It assessed the degree of human impact on all the shorelines in the community, including the Recreation Bay. This study confirmed the extent of sediment that had accumulated and also measured the high levels of phosphorus and biological oxygen demand in the water (these parameters confirm the presence of agricultural nutrients).

2011: Recreation Bay Assessment – Groupe Hémisphères

This study built on the work from 2008 with a specific focus on the Recreation Bay and was an attempt to determine the cause of the problem. The depth of sediment in the bay was measured in more detail and mapped. The study revealed that the area just downstream from the remnant natural island (a bottleneck) had the most sediment and this area was identified as a ‘shoal’. A preliminary model was completed that assessed the improvement to flow in the bay by the construction of a 10 m wide channel through the sediment.

2012 – 2013: Fish and Fish Habitat Study – AECOM

Whenever major work is considered, including dredging, it is very important to understand what the potential environmental impacts of the proposed work may be on the existing wildlife. To understand this, we needed to know what species were present in the bay. Fish surveys were done in numerous locations within the community including in the bay and also identified important habitat. The study concluded that the Recreation Bay was considered ‘very good’ fish habitat. Fifteen fish species were recorded in the inventory and they were generally healthy. The study did note, however, that the habitat was at risk because of the on-going sediment accumulation.

2014: Fish Characterization – Groupe Hémisphères

This study focused on the Recreation Bay and the development of a more comprehensive understanding of the species found there. We were specifically looking for Species at Risk such as the American eel and classifying the wetland habitat and plants found on either side of the bay. This work also concluded that the bay had very good fish habitat and recommended that work take place to maintain this habitat.

2015: Recreation Bay Modeling – Hydrosoft SA

With the information gained from previous studies, we now needed to understand how we should intervene in the bay to ensure that we achieve our desired goal and the work will be sustained. We developed a three-dimensional model that looked at all aspects of the flow through the bay. This included consideration of waves, wind patterns, flows from the St. Lawrence and Chateauguay rivers, sediment loads into the bay from various sources and the operation of the Seaway Canal. Equipment was installed in the bay for two months, one month in the spring and one in the fall, to obtain an accurate picture of what was occurring in the bay.

We looked at how different strategies would affect flow and sediment deposition in the bay. Three approaches proved to be the most beneficial, particularly when they were all done at the same time. These included:

  1. Dredging material from the shoal area;
  2. Harvesting aquatic plants regularly; and
  3. Increasing flow in the Seaway by modifying the operation of the Ste. Catherine locks.

These three options were adopted as a preferred approach and were carried forward to the detailed design stage.

2016 – 2017: Recreation Bay Detailed Design – AECOM

KEPO has developed a detailed design for the Recreation Bay to enhance the environment in the area and ensure the continued use for the community. In addition to the three flow enhancements mentioned above, three other areas in need of improvement have been identified. These include:

  1. Naturalizing the shoreline of Tekakwitha Island;
  2. Improving the soil on the island and creating pollinator habitat; and
  3. Enhancing the two wetlands that exist on either side of the bay, including Turtle Bay.

These measures, in conjunction with the dredging and maintenance of aquatic plants will restore and diversify ecosystems in the bay and create new opportunities for community enjoyment and use of the area.

2017-2018: Information Kiosk & Open Houses

KEPO hosted a public information and feedback kiosk on July 6, 2017  at the Services Complex, as well as two public open house events on May 24 2017 and October 16 2018 at the Golden Age Club. The open houses included the proposed designs for the restoration of the Recreation Bay area, including the strategy for dredging, aquatic plant management, the creation of natural areas and, after incorporating feedback from the community, the development of a beach.

2019: Restoration Project Begins

The Recreation Bay Restoration Project will begin in the fall of 2019. KEPO will be communicating with the community on a regular basis, and a staff member will be on-site throughout this process to limit the disruption as much as possible. Implementation activities will begin in fall 2019 and continue throughout the spring, summer, and fall of 2020.

Your feedback and ideas for the Recreation Bay are always welcome. Please contact KEPO at (450) 635-0600.
