Flood preparation measures in First Nations communities

ISC provides funding support for flood preparation and mitigation measures in First Nations communities. This includes up to $8.6 million in March and April 2019 to prevent spring flooding in 34 at-risk communities in Ontario, British Columbia, New Brunswick, Newfoundland and Manitoba. Specific examples in each region are set out below.

As well, as of December 31, 2018 and since Budget 2016 was announced, 45 structural mitigation projects have been completed or are underway, benefiting 53 First Nations communities. Projects include improving dikes, upgrading culverts and flood mitigation planning.


A surface and storm water mitigation program is in progress for Indian Island First Nation in New Brunswick. The program covers surface and storm water management planning, housing infrastructure review and upgrades to community drainage network.

Overland flooding due to melting snow in spring is common in Atlantic First Nations, especially in New Brunswick. In 2019, ISC has supported 9 New Brunswick First Nations for emergency removal of excessive snowpack from areas which have been historically vulnerable to overland flooding due to snow melt:

  • Bouctouche
  • Eel Ground
  • Eel River Bar
  • Elsipogtog
  • Esgenoôpetitj
  • Indian Island
  • Metepenagaig
  • Pabineau
  • Tobique

The Elsipogtog First Nation in New Brunswick has been historically vulnerable to overland flooding due to severe rainstorms and rapid snow melting. In the 2017-2018 fiscal year, ISC funded Elsipogtog First Nation to conduct a flood mitigation study. The study was completed in fiscal 2018-2019 and provides the basis for the development of a plan. In March 2019, ISC funded a study to look at mitigation measures that could be put in place to reduce the recurring flooding in about 70 homes.

ISC has also supported the Mushuau Innu First Nation in Newfoundland and Labrador for emergency snow removal to prevent flooding from snow melt.

An overland flooding mitigation program for the Eskasoni First Nation in Nova Scotia has been underway since 2016. Acadia First Nation, also in Nova Scotia, started a flood mapping study in 2018.

In April 2015, Canada and the province of Prince Edward Island signed a 4 year agreement to ensure Abegweit and Lennox Island First Nations receive the same level of emergency management services as every other Islander.


ISC supports First Nations preparedness activities in Quebec on an annual and recurring basis, including emergency management plan updates, exercises and training.

Non-structural mitigation measures were implemented with the financial support of ISC, such as:

  • addition of Waterguard system in houses that were at risk of flood due to high water tables (Nutashkuan First Nation)
  • sandbags in store in case of floods (Kanesatake, Pekuakamiulnutsh Takuhikan)
  • alert system and evacuation plans (Chisasibi, Wemotaci)

In addition to direct investments, ISC supports First Nations by way of the following measures and projects:

  • regional agreement with the Canadian Red Cross for assistance during evacuations
  • National Symposium on Resilience in First Nations
  • training and exercises in risk management, emergency management planning, incident command system and emergency operation centres
  • flood watch and flood response in all First Nations with the collaboration of the Provincial government

The Ministère de la Sécurité publique du Québec is responsible for civil security in the province and supports local municipalities in the protection of their citizens and property against disasters.

The Quebec-ISC bilateral agreement includes provincial assistance to First Nations in Quebec during disasters and allows the federal and provincial governments to collaborate on disaster risk management.


ISC supports emergency preparedness activities for all First Nations in Ontario. ISC contracts the Ontario First Nations Technical Services Corporation to work with First Nations to:

  • review and update their emergency management plans
  • train and test the preparedness of First Nations' staff

ISC also supports flood watch for the Mushkegowuk Council and the First Nations communities of:

  • Fort Albany
  • Attawapiskat
  • Kashechewan
  • Weenusk
  • Moose Cree
  • Fort Severn

Other ISC-supported activities include:

  • the Mushkegowuk Council's feasibility study for a culturally appropriate evacuation camp to serve their communities, some of which are forced to evacuate yearly due to flooding hazards
  • funding for the Mushkegowuk Council to send James Bay emergency management coordinators to the Flood and Fire Symposium hosted by the Ontario Office of the Fire Marshal and Emergency Management

Since 1992, Canada has had a Memorandum of Understanding with Ontario to ensure First Nations receive emergency response support, including for flooding.


Prevention and mitigation efforts are crucial to avoiding future situations such as the severe 2011 Manitoba flood. As of May 2019, ISC has invested more than $80 million to protect Manitoba First Nations from future flooding. This included approximately $54.9 million to construct permanent dikes or make temporary dikes permanent at 11 First Nations in Manitoba:

  • Sioux Valley
  • Opaskwayak
  • Canupawakpa
  • Sandy Bay
  • Ebb and Flow
  • Lake Manitoba
  • O-Chi-Chak-Ko-Sipi
  • Little Saskatchewan
  • Poplar River
  • Berens River
  • Kinonjeoshtegon

A permanent ring dike is also in place at Roseau River Anishinabe First Nation since 2004.

With support from ISC, the Assembly of Manitoba Chiefs organized the Manitoba Flood Preparedness Forum in February 2019, which brought together First Nations in Manitoba routinely affected by flooding. Participants discussed strategies and exchanged knowledge related to flood outlook, services, tools and templates in order to increase awareness and capacity around flood preparation, response and recovery.

In response to the imminent threat of spring flooding and with support from ISC, 21 First Nations communities in Manitoba undertook flood prevention activities such as clearing and steaming culverts and drains and clearing out ditches of brush, snow and debris.

With funding support from ISC, the Interlake Reserves Tribal Council is working to complete the fourth phase of its Command Centre project to serve the First Nations of:

  • Dauphin River
  • Kinionjeoshtegon
  • Lake Manitoba
  • Little Saskatchewan
  • Peguis
  • Pinaymootang

Numerous training sessions were held with the 6 communities to enhance their emergency management preparedness capabilities.

With funding from ISC, Fort Alexander First Nation is undertaking shoreline erosion protection works and Peguis First Nation is doing a feasibility study on work needed to mitigate flood damage to housing.


ISC continues to make significant investments to reduce the potential for flooding that threatens residents, houses and infrastructure in Saskatchewan First Nations communities.

In addition to direct investments to First Nations in Saskatchewan, ISC has an arrangement with the province of Saskatchewan to provide emergency response and recovery support to First Nations.

With investments from ISC, structural mitigation projects to address flooding are also underway in the following First Nations communities:

  • Mistawasis Nehiyawak Band
    • project to improve local drainage to better deal with spring runoff
  • Lac La Ronge First Nation Stanley Mission Reserve
    • multi-activity project including removing damaged culverts and installing replacements, repairing damaged roadways and re-grading existing ditches
  • Montreal Lake Cree Nation
    • drainage improvements to reduce seasonal flooding risk

The Red Earth Cree Nation, with funding from ISC, is conducting flood plain mapping of the Rice and Carrot Rivers to assist in planning to reduce impact of flooding on the community.

Annual Emergency Management Forums bring together First Nations and tribal councils in Saskatchewan to gather information toward developing emergency management. This includes preparing all-hazard plans, sharing community experiences and best practices and networking to develop partnerships toward enhancing community capacity and resiliency. The forums are supported by ISC through funding to the forum organizer, the Prince Albert Grand Council.


Funded by ISC, the Alberta Bow River Basin Flood Hazard Assessment Project assesses flood hazards for the parts of the Bow River Basin flowing through the Siksika, Tsuut'ina and Stoney Tribe Nations to help the First Nations develop options for flood mitigation.
