Who should we blame for Ontario Wildfires?
Canadian Forestry companies spray glyphosate over the forest which lead to the massive wildfire in Northern Ontario!!!
Glyphosate acts as a systemic desiccant, meaning it kills or severely weakens target plants. As the treated vegetation dies and dries out, it leaves behind large amounts of dead, combustible biomass that acts as highly flammable kindling. Forest Ecosystem Shifts: In forestry, glyphosate is frequently used to eliminate broadleaf trees and shrubs (like aspen and birch) to promote the growth of coniferous trees (commercially used) like spruce and pine. Broadleaf trees retain more moisture and burn much slower, naturally acting as firebreaks. Removing them replaces diverse ecosystems with simplified, highly combustible conifer monocultures.
Forestry companies spray glyphosate for one primary reason: to maximize profits by accelerating the growth of valuable softwood timber (pine and spruce).
When a forest is clear-cut, the sudden abundance of sunlight triggers a rapid explosion of fast-growing, native broadleaf trees (like poplar and birch) and shrubs (like raspberry bushes). These deciduous plants outcompete and “choke out” the slower-growing conifer seedlings that the timber industry relies on for lumber, pulp, and paper.
Spraying glyphosate alters this natural process through three main mechanisms:
1. Eliminating Resource Competition
Glyphosate is a systemic herbicide, meaning it kills broadleaf plants but leaves most conifers unharmed. By spraying a harvested area from helicopters, companies kill off the competing vegetation. This ensures that 100% of the soil’s nutrients, water, and sunlight go directly to the target conifer crop.
2. Speeding Up the “Free-to-Grow” Deadline
By law in provinces like Ontario, forestry companies are legally responsible for regenerating the forests they log. They must prove to the government that their replanted trees have reached a “free-to-grow” status—meaning the seedlings are tall and healthy enough to survive without being overtaken by wild brush. Using glyphosate is the fastest, most reliable way to hit this mandatory legal deadline.
3. Creating Predictable Timber Crop Monocultures
Industrial logging relies on predictable, uniform forests. It is highly inefficient for heavy logging machinery to harvest a scattered mix of trees. Glyphosate allows companies to effectively treat public lands like commercial farmland, turning a diverse, complex ecosystem into a predictable, single-species conifer plantation that is easy to clear-cut again in 40 to 60 years.
Why Not Use Other Methods?
Compared to the alternatives, glyphosate is highly favored by the industry because it is:
- Inexpensive: Aerial spraying covers thousands of hectares in hours for roughly $200–$300 per hectare.
- Effective: It kills the root systems of aggressive plants, preventing them from sprouting back the next year.
In contrast, hiring ground crews to manually cut down competing brush with chainsaws costs double the price ($500–$600 per hectare), is physically dangerous work, and often causes plants like poplar to send up even more aggressive shoots from their surviving roots.
How Glyphosate Affects Moose: The Threat of Starvation
Forestry spraying profoundly harms moose and bears indirectly by destroying their primary food sources and altering their critical habitats.
The impact on these animals comes down to a radical change in forest biology rather than direct poisoning:
Moose are “browsers” that rely heavily on eating woody, broadleaf plants to survive.
- Wiping Out Winter Browse: The target of forestry spraying includes willow, trembling aspen, birch, and fireweed. These are a moose’s primary winter food sources. Studies on forest spraying indicate that glyphosate can temporarily reduce winter forage availability by up to 96%.
- Habitat Displacement: Without food, moose are forced to abandon sprayed blocks. Multi-year studies tracking moose presence confirmed a sharp decline in moose sightings and population density in areas treated with glyphosate. Conifer monocultures (spruce and pine) offer shelter but do not provide the nutrition moose need.
How Glyphosate Affects Black Bears: Destroying the Calorie Supply
Black bears are heavily dependent on massive caloric intake, particularly leading up to winter hibernation.
- Eliminating Berry Patches: Clear-cut areas naturally explode with sun-loving, berry-producing shrubs like wild raspberry, cranberry, huckleberry, and salmonberry. These are critical high-calorie feeding grounds for bears.
- Destroying Foraging Grounds: Because glyphosate is designed to eliminate these exact broadleaf shrubs to clear space for timber, it effectively wipes out massive seasonal bear pastures. Bears are forced to travel much greater distances to find sufficient food, increasing their stress levels and chances of human-bear conflicts.
The Impact on Amphibians (Frogs, Toads, & Salamanders)
While pure glyphosate targets a biological pathway found only in plants, extensive field and laboratory research demonstrates that commercial glyphosate-based herbicides (GBHs) severely impact pollinators and amphibians through chemical additives and extreme habitat destruction.
Amphibians are highly vulnerable to environmental shifts because they have permeable skin and rely on temporary woodland pools (vernal pools) to breed.
- The Surfactant Danger: Pure glyphosate has low direct toxicity, but commercial forestry products (like VisionMax) include chemical surfactants—specifically polyethoxylated tallow amine (POEA)—to help the herbicide stick to and penetrate plant leaves. Research shows POEA directly damages cell membranes, disrupting the sensitive respiratory skin and gills of tadpoles and frogs, which can cause mass mortality if wetlands are oversprayed.
- Loss of Shade and Humidity: Amphibians require a cool, damp forest floor to survive. Eliminating the dense broadleaf canopy and leafy undergrowth strips away the shade, causing the microclimate to dry out and exposing these creatures to lethal dehydration.
- Vernal Pool Vulnerability: While Ontario enforces mandatory 20-metre spray buffers around major public waterways, small, temporary vernal pools are often left unprotected. Runoff and aerial drift accumulate in these shallow pools, contaminating the exact locations where amphibians lay their eggs.
The Impact on Pollinators (Wild Bees & Butterflies)
Forestry spraying targets the very plants that forest pollinators depend on for survival.
- Starvation and Habitat Loss: Eliminating flowering “weed” species like wild raspberry, fireweed, and clover starves wild bees and butterflies of their primary sources of nectar and pollen.
- Reduced Flower Fertility: University of British Columbia (UBC) research discovered that even if forest flowers survive a low-dose exposure from spray drift, the chemical alters the plant’s morphology, reducing flower fertility and making them significantly less attractive to pollinators.
- Sublethal Gut Disruption: Emerging science reveals that when foraging bees ingest glyphosate-laden nectar, it destroys their beneficial gut bacteria. This gut microbiome imbalance severely weakens their immune systems, making them highly vulnerable to fatal infections.
- Navigational Failure: Low-level exposure alters a bee’s central nervous system, impairing its learning capacity, memory, and ability to navigate. Impacted bees often become disoriented and fail to return to their hives.
The Broader Forest Food Web
When insects and amphibians decline, the entire food chain in Northern Ontario is disrupted:
- Songbird Starvation: Insectivorous forest birds depend on a massive supply of caterpillars and insects to feed their chicks during the spring nesting season.
- Soil Biological Decline: Glyphosate binds tightly to soil particles, suppressing beneficial soil fungi and earthworms, which are essential for nutrient cycling and healthy forest regeneration.
What Canadian provinces allow to spray glyphosate on their territory?
- Quebec: Banned all herbicide spraying in its forests for timber management. The province uses manual or mechanical vegetation control instead.
- British Columbia: While historically one of the largest users of glyphosate in forestry, the provincial government has committed to phasing out the chemical, and herbicide use has declined dramatically in recent years.
- Ontario & New Brunswick: Widely use glyphosate on Crown lands to clear out broadleaf vegetation (like aspen) so that planted softwoods can grow without competition. New Brunswick traditionally has one of the highest rates of glyphosate use per land mass in the country.
- Alberta, Saskatchewan, & Manitoba: All permit the use of glyphosate in forestry, though agricultural spraying heavily dominates overall usage in the Prairie provinces.
Forestry experts and environmentalists warn that its use exacerbates wildfire intensity. The herbicide kills moisture-rich broadleaf trees (e.g., poplar and birch), replacing diverse ecosystems with highly flammable, continuous conifer monocultures that burn significantly faster and hotter.
Indigenous communities, such as the TEK Elders and Nipissing First Nation, along with several municipalities in Northern Ontario, are actively pushing for an end to the spraying, citing concerns over ecosystem damage, reduced biodiversity, and the creation of “tinderbox” landscapes.
Ecological & Fire Impact Breakdown
- Removal of Natural Firebreaks: Broadleaf trees and deciduous shrubs retain more moisture and burn much slower, naturally slowing the spread of flames. Glyphosate eliminates these, removing natural firebreaks.
- Increased Flammability: Softwoods (pine and spruce) favored for commercial timber contain highly resinous, combustible foliage. Replacing a mixed-wood forest with a dense conifer plantation increases potential fire intensity.
- Dry Biomass: The systemic desiccation (drying out) of sprayed vegetation leaves behind brittle, dead biomass that serves as tinder in hot, dry conditions.
How much do we pay for Environmentally Unfriendly Decisions?
Ontario taxpayers do not directly fund the spraying of chemical herbicides on public Crown forests. Under Ontario’s forestry renewal system, licensed logging companies are legally mandated to regenerate the forests they harvest and must pay for their own vegetation management, which averages $200 to $300 per hectare ($10,000 m²) for aerial spraying.
However, taxpayers still carry significant indirect costs linked to government oversight, regulation, and long-term public liabilities.
- Government Oversight and Administrative Costs
The provincial government uses taxpayer dollars to manage, permit, and monitor the spraying program. This public funding flows through the Ministry of Natural Resources (MNR) and covers:
- Permit Approvals: Reviewing and approving aerial spray maps and operations for thousands of hectares of Crown land annually.
- Regulation Compliance: Enforcing mandatory buffer zones around public waterways, residential communities, and ecologically sensitive wetlands.
- Scientific Research: Funding state and provincial environmental impact assessments to track long-term chemical safety and residue levels.
2. The Indirect Taxpayer Liability
While the physical act of spraying is privately financed, critics and environmental economists point out that the public absorbs several hidden economic burdens:
- Escalating Wildfire Costs: Taxpayers fund emergency wildfire suppression. If chemical spraying converts mixed-wood ecosystems into highly flammable conifer monocultures, it elevates the intensity and suppression costs of future forest fires.
- Environmental Remediation: Public funds are routinely tapped to monitor watershed health and manage declines in local biodiversity (e.g., impact on pollinators and water systems).
The Herbicide Era started in the 1950s
- The Chemicals: Forestry companies transitioned to heavy use of phenoxy herbicides like 2,4-D and 2,4,5-T (the chemical components that made up Agent Orange). In 1976, commercial forestry shifted almost entirely to glyphosate (the active ingredient in Roundup), which today accounts for over 93% of all forest herbicide application in Canada.
- Why They Started: The post-war era introduced heavy, mechanical “clear-cutting.” When a diverse forest is completely clear-cut, sun-loving, fast-growing deciduous plants (like trembling aspen, poplar, birch, and berry shrubs) rapidly aggressively regenerate and crowd out slower-growing conifer seedlings.
- The Goal: To eliminate resource competition. By spraying these chemicals from helicopters a few years after a clear-cut, companies systematically kill off all broadleaf “weed” trees. This allows softwoods (like pine and spruce) to absorb all the sunlight, water, and soil nutrients, allowing them to grow faster and straight. Ultimately, it turns diverse natural forests into highly profitable, single-species crop plantations for lumber and pulp.
