Armstrong, Whitesand and Collins First Nations Evacuated as Northwestern Ontario Wildfires Combine With Extreme Heat: A Practical Guide for Evacuees, Thunder Bay Hosts, and Anyone Under Smoke

What This Means for You

A fast-moving combination of wildfire and record heat forced mandatory evacuation orders across northwestern Ontario starting late Monday night, July 13, into Tuesday morning, July 14, 2026. Ontario Provincial Police issued evacuation orders for Armstrong and Whitesand First Nation shortly before 10:30 p.m. ET Monday, followed by Lac des Mille Lacs First Nation just after 12:15 a.m. ET Tuesday, and Collins First Nation and Cushing Lake at 5:30 a.m., according to CBC News. The Globe and Mail additionally reported an evacuation order for Lac La Croix First Nation, with Rainy River District and Gull Bay First Nation identified as threatened and told to prepare. Evacuees from these communities are arriving in Thunder Bay, where the Canadian Red Cross is assisting with intake, according to CBC News.

This is happening during a severe heat warning across much of northern Ontario, with Environment and Climate Change Canada reporting temperatures approaching 40 C with humidex Monday and warning the combined heat-and-smoke event will likely continue into Wednesday. If you or someone you know is being evacuated, hosting evacuees, or simply living under the smoke plume stretching across Ontario, here is our practical guide broken down by situation.

If You're Under an Evacuation Order in Armstrong, Whitesand, Collins, Lac des Mille Lacs, or a Nearby Community:

Immediate action (first hour):

Follow your community's designated evacuation route and destination — do not self-direct to Thunder Bay by an unconfirmed route. With Highway 11 closed in both directions between Highway 633 and 623 (east of Atikokan) and Highway 599 closed southbound between Highway 516 and Mishkeegogamang First Nation as of this week, road access is actively shifting. Confirm your route through your band office, OPP, or Emergency Management Ontario before departing.
Register with the Canadian Red Cross once you reach Thunder Bay, even if you're staying with family or in a hotel rather than a group shelter. Registration is what triggers per diem, accommodation, and transportation support under the federal Emergency Management Assistance Program (EMAP), and it's how family members can find you if you're separated during evacuation.
Bring medications, identification (status card, health card, driver's licence), and phone chargers before anything else. In a rapid overnight evacuation like this one, most households will not have time for a full packing list — prioritize the items that are hardest to replace quickly on the road.

Within 24–48 hours:

Ask your Red Cross or band emergency coordinator specifically about EMAP-funded per diems. Indigenous Services Canada's Emergency Management Assistance Program reimburses 100% of eligible response and recovery costs for affected First Nations, including food and hygiene per diems, hotel or group-lodging accommodation, and transportation from your community to a safe location. You should not be paying out of pocket for basic evacuation needs — ask early if you are.
Keep every receipt anyway. Even with EMAP support, gas, incidental food, and replacement items (a phone charger, a change of clothes) are easier to claim back with a receipt in hand than from memory later.
Check in with your employer if you work outside your community. Federal Employment Insurance waives the standard one-week waiting period for work loss tied to a declared disaster in affected regions — ask Service Canada about disaster-related EI if evacuation costs you shifts.

If You Live in Thunder Bay and Want to Help, or Are Sheltering Evacuees:

What the city needs most right now is not always what feels most helpful. Thunder Bay has hosted large-scale wildfire evacuations before — including more than 200 formal evacuees from Pikangikum First Nation in 2019, plus roughly 600 more who self-evacuated to the city. Based on that pattern, formal intake through the Red Cross is generally more effective at matching donations and space to need than informal drop-offs at reception points.

If you have a spare room or basement suite, register it through the Red Cross rather than posting it on social media. Verified, insured hosting arrangements protect both you and evacuees, and Red Cross intake can match households to appropriate space (families with young children, elders needing accessible housing, etc.).
Check the City of Thunder Bay's current fire ban before lighting anything outdoors — the city implemented a fire ban this week given the extreme wildfire hazard rating for the Thunder Bay, Dryden, Fort Frances, and Kenora sectors.
If you're hosting evacuees with health conditions, know that smoke and heat compound each other. Anyone with asthma, COPD, or heart disease is at elevated risk during a combined heat-and-smoke event, regardless of whether they were forced to evacuate or are just visiting your home.

If You're Anywhere Under the Smoke Plume or Heat Warning (Most of Northern Ontario and Beyond):

You do not need to be near a fire to be affected. Wildfire smoke from these fires, combined with smoke drifting from U.S. fires, has been reported affecting air quality well beyond the immediate fire zone.

Check the Air Quality Health Index (AQHI), not just the temperature, before planning outdoor activity. When AQHI reaches 7 or higher, limit prolonged outdoor exertion, especially for children, older adults, and anyone with a respiratory or cardiac condition.
Identify one "clean air" room in your home — ideally with the fewest windows — and run a HEPA air purifier or a box-fan-and-furnace-filter setup there if you don't own a purifier. Keep windows and doors closed during peak smoke hours.
Treat this as a two-hazard event, not one. Heat warnings tell you to stay cool and hydrated; smoke advisories tell you to stay indoors with filtered air. When both apply simultaneously, as they do this week, air-conditioned indoor space with filtration is your best option — and public cooling centres serve double duty for exactly this reason.
Reschedule strenuous outdoor work or sports for early morning if you must be outside, since both heat and smoke concentrations are typically worse in the afternoon.

For All Canadians:

Even outside Ontario, this event is a useful checkpoint. Canada's 2026 fire season had already burned roughly 1.4 million hectares nationally as of July 10, with more than 3,100 fires recorded and nearly 800 active, according to federal wildfire tracking. If your region hasn't had a fire scare yet this summer, that is exactly the moment to build a go-bag and confirm your provincial emergency alert subscription — not after the alert arrives.

The News: What Happened

According to CBC News, Ontario Provincial Police issued mandatory evacuation orders for Armstrong and Whitesand First Nation shortly before 10:30 p.m. ET on Monday, July 13, 2026, via a Facebook post. Lac des Mille Lacs First Nation and surrounding communities were ordered to evacuate just after 12:15 a.m. ET Tuesday, with Collins First Nation and Cushing Lake added to the evacuation list at 5:30 a.m. The Globe and Mail additionally reported an evacuation order in place for Lac La Croix First Nation, and said Rainy River District and Gull Bay First Nation were also under threat, with residents there asked to prepare for possible evacuation. Communities further west, including Ignace and the Highway 633 area, were told to be ready to leave on short notice.

According to the Ministry of Natural Resources and Forestry, as reported by the Weather Network and the Globe and Mail, the province was managing roughly 160 active wildland fires as of this week, including 128 in the Northwest Region alone — 53 classified as not under control, 8 being held, 4 under control, and 63 under observation. Thirty-one new fires were discovered on July 13 alone, according to regional fire updates. Highway 11 was closed in both directions between Highway 633 and Highway 623, east of Atikokan, and Highway 599 was closed southbound between Highway 516 and Mishkeegogamang First Nation.

Environment and Climate Change Canada issued a severe heat warning across much of northern Ontario, with temperatures approaching 40 C with humidex on Monday and forecasters warning the heat event would likely persist into Wednesday before easing. According to CBC News, evacuees from Armstrong, Whitesand, and Collins First Nations began arriving in Thunder Bay this week, with the Canadian Red Cross assisting with intake. The City of Thunder Bay implemented a fire ban and reported worsening local air quality as smoke from the regional fires drifted into the city. Wabakimi Provincial Park, north of Armstrong, has been closed through at least July 20 due to extreme fire conditions.

Analysis: Why This Matters

Based on our analysis of Ontario's wildfire season pattern, this week's evacuations are notable less for any single fire and more for the compounding of two hazards — extreme heat and wildfire smoke — hitting the same communities simultaneously, with a third stressor (mandatory evacuation and displacement) layered on top for several First Nations.

First, the timing and scale. Thirty-one new fires discovered in a single day (July 13) and 128 active fires in one region point to explosive fire growth under sustained heat and likely low humidity, rather than a single large blaze. This pattern — many simultaneous starts rather than one dominant fire — historically strains firefighting resources more than a single large fire does, because crews and aircraft must be distributed across multiple active fronts rather than concentrated.

Second, the population affected. Armstrong, Whitesand First Nation, Collins First Nation, Lac des Mille Lacs First Nation, and Lac La Croix First Nation are remote, fly-in or limited-road-access communities in Ontario's Far North and boreal interior. Evacuating these communities is logistically harder and typically takes longer than evacuating a highway-accessible town, and reception in Thunder Bay — as in the 2019 Pikangikum evacuation — places real strain on the city's shelter, health, and social-service capacity even with Red Cross and federal support.

Third, the health dimension. A combined heat-and-smoke event is measurably more dangerous than either hazard alone. Heat increases respiratory rate and cardiovascular strain; smoke particulate (PM2.5) does the same through a different mechanism. Public health researchers have found that hospital visits for respiratory and cardiac complaints rise disproportionately during compound heat-smoke events compared to the sum of each hazard's individual effect.

Historical Context

Northwestern Ontario has a recurring pattern of large-scale First Nations wildfire evacuations, including the 2019 Pikangikum evacuation that brought more than 800 people (formal and self-evacuated combined) to Thunder Bay, and repeated evacuations in the 2021 and 2023 fire seasons. Canada's overall 2026 fire season had already burned approximately 1.4 million hectares nationally by July 10, according to federal wildfire tracking, with 796 active fires and 60 considered out of control at that point — figures that have clearly worsened in the two weeks since, given this week's additional 31-fire single-day discovery in the Northwest Region alone.

What Happens Next

In the immediate term, expect the evacuation order list to expand or contract based on fire behaviour over the next 48–72 hours as the heat warning eases; Ignace, Crystal Lake, and the Highway 633 corridor are the communities most likely to see new orders if conditions worsen. In the medium term, watch for a federal-provincial disaster financial assistance response specific to the evacuated First Nations, coordinated between Indigenous Services Canada and Ontario's Ministry of Emergency Preparedness and Response. Re-entry timelines for remote, fly-in-access communities like these are typically longer than for highway-accessible towns, given the added logistics of transporting residents and verifying community infrastructure (water, power, food supply) before return.

Your Action Plan

Immediate (This Week):

Evacuees: register with the Canadian Red Cross in Thunder Bay even if staying with family or in a hotel
Evacuees: confirm evacuation route status before travelling — Highways 11 and 599 have active closures
Anyone under smoke: check today's AQHI reading before spending time outdoors
Anyone under the heat warning: identify your nearest cooling centre or air-conditioned public space

Short-term (This Month):

Evacuees: ask your Red Cross or band coordinator about EMAP per diem and accommodation support
Thunder Bay residents: register spare housing capacity through the Red Cross rather than informal channels
Anyone with a respiratory or cardiac condition: confirm you have at least 5–7 days of medication on hand
Households anywhere in fire-prone Canada: build or refresh a 72-hour go-bag

Long-term (This Year):

Subscribe to Ontario's emergency alert system (ontario.ca/alert) and your local band or municipal alert channel
If you live in a remote or fly-in community, ask local leadership about the current wildfire evacuation plan and reception-community arrangements
Review whether your homeowner or tenant insurance includes smoke damage and additional-living-expense coverage
Install a HEPA air purifier or confirm your furnace filter is rated for wildfire smoke (MERV 13 or higher)

Other Perspectives

Provincial Government:

Ontario's Ministry of Emergency Preparedness and Response said the Provincial Emergency Operations Centre is coordinating closely with the Ministry of Natural Resources and Forestry, Indigenous Services Canada, and affected municipalities to manage evacuations across the Northwest Region, according to a ministry statement reported by regional outlets.

Ministry of Natural Resources and Forestry:

The ministry's fire update described "increased fire behaviour" under hot, dry conditions and confirmed 31 new wildland fires discovered on July 13 alone, underscoring how quickly the regional fire count grew within a single day.

Evacuated Communities:

First Nations affected by the orders, including Armstrong, Whitesand, Collins, and Lac des Mille Lacs, are coordinating evacuation logistics through their band offices in parallel with OPP and provincial evacuation notices — reflecting the dual jurisdiction that shapes how evacuations unfold in these communities.

Public Health Officials:

Environment and Climate Change Canada's guidance during this event has emphasized "prioritizing keeping cool" under the combined heat-and-smoke conditions, reflecting public health messaging that treats compound heat-smoke events as a distinct, higher-risk category rather than two separate advisories.

Note: Including multiple perspectives doesn't imply all views are equally valid, but ensures readers can make informed judgments.
