Americans often picture Canada as a vast northern forest – an endless expanse of pristine wilderness. But the truth is far more complex and increasingly relevant to U.S.–Canada policy debates. [some emphasis, links added]
Eighty‑nine percent of Canada is Crown land, owned by federal or provincial governments. Yet only about 10–12% of that land receives detailed ecological monitoring.
This matters because U.S. trade policy, Canadian conservation policy, and federal herbicide permitting are now combining to reshape North America’s forests in ways few Americans recognize.
Over the past 20 years, Canada’s sawmill and pulp‑and‑paper sectors have entered a steep decline. Statistics Canada and industry reports show that mill closures have accelerated, especially in western Canada, where over 30% of softwood lumber capacity has disappeared. Employment has dropped sharply. Entire forestry towns have hollowed out.
And while multiple factors contribute — mountain pine beetle damage, wildfire losses, transportation bottlenecks — the most overlooked driver is the federal government’s long‑standing approval of spraying Roundup (glyphosate) herbicide across millions of hectares of Crown forests.
For decades, glyphosate has been used to kill broadleaf species – birch, aspen, poplar – so that commercially valuable conifers can dominate.
But this practice has consequences. Roundup creates monoculture conifer stands, which are more resin‑rich and significantly more flammable than mixed‑species forests.
Instead of diverse, moisture‑retaining ecosystems, Canada is producing vast tracts of single‑age, single‑species pine and spruce – exactly the kind of forests that burn explosively under extreme fire weather.
The result is a continental paradox: Policies meant to “manage” forests have instead created more combustible landscapes, contributing to the anomalous rise in total annual area burned.
The deterioration of Canada’s forestry is also being accelerated by domestic policy. Rising carbon taxes on diesel and gasoline – critical fuels for logging, hauling, and mill operations – have increased costs across the supply chain.
New layers of regulation slow approvals and reduce harvest flexibility. And when pulp mills close, sawmills lose buyers for residual chips and sawdust, further undermining their economics.
But the most consequential impact of this industrial contraction is ecological. Canada’s parklands – where monitoring exists – show a clear trend of rapidly aging boreal forests, with large stands now reaching 70 to 120 years old.
In Alberta’s eastern foothills, provincial parks contain dense, overmature, fuel‑loaded forests primed for high‑intensity wildfires. Decades of fire suppression, beetle kill, drought, and heavy recreational pressure have created extreme fire risk.
As Parks Canada itself warns, “the reduction or exclusion of fire as a natural process … leads to increased risk of wildfires.”
The consequences are here. Alberta’s Jasper National Park recently almost burned to the ground when extreme fire weather collided with decades of fuel accumulation, beetle‑killed forests, a highly vulnerable townsite, and infrastructure failures.
Nonetheless, long‑term fire data tell a more nuanced story.
According to Canada’s National Burned Area Composite and CIFFC wildfire statistics, forest‑fire frequency has declined since the 1980s. Canada is experiencing fewer fires overall.
What has changed is the total area burned, which had remained relatively moderate for decades but then spiked dramatically in 2023 and again in 2025, producing two of the worst years for fires in modern Canadian history.
These spikes reflect the dangerous combination of aging forests, heavy fuel loads, glyphosate‑driven monoculture, and extreme fire weather – not an increase in ignition frequency.
Meanwhile, federal biodiversity reports show that parks are not experiencing net improvement. Most ecosystems are stable, but among those changing, declines outnumber gains. And crucially, non‑park Crown lands are not monitored at all, meaning there is no empirical basis to claim that conservation designations improve biodiversity.
Yet Ottawa is moving ahead with its flagship 30×30 agenda – a plan to place 30% of Canada’s land and water under conservation status by 2030.
In practice, this means restricting forestry across vast areas when forests are aging, fuel‑loaded, and increasingly prone to extreme fire behavior.
By limiting private‑sector utilization, 30×30 will increase fuel loading, exacerbate forest aging, and reduce the thinning and harvesting activities that mitigate catastrophic wildfire.
For Americans concerned about lumber prices or wildfire smoke drifting south, the lesson is simple: Canada’s forests are increasingly unmanaged, aging, and burning, not because Canadians don’t care, but because the economic and policy frameworks governing those forests are pushing the country toward less active management.
North America needs forestry – not just parks – to remain resilient.

The majority of the problems with out of control forest fires is envirowackos getting the prescribed burning cancelled years ago !!!
“…inaccessible to human fire crews.” Crater Lake National Park, Oregon, in the mid-nineties. A thunderstorm came up the Rogue River valley and passed over the western portion of the Park. No roads and few walking tracks. Eleven columns of smoke after it passed. Three helicopters with buckets. “All dumped on.” Ten days later one of them flared up. That fire was ‘good’ enough that T-shirts were printed up with it’s name. It took several days to knock it down.
Interesting area. We monitored the local Forest Service frequencies. One evening, two small fires on Mt Thielsen had smokejumpers dropped on them. They walked out two days later. (We were “South Host”, Diamond Lake Campground, and were issued a USFS handheld two-way radio.)
The vast majority of the wildfire smoke drifting from Canada into the United States originates in remote, unmanaged boreal forests that are physically inaccessible to human fire crews.
Canadian wildfire smoke that engulfed large american cities was very rare before the 1970s
Recent decades have seen a dramatic increase in the area burned in Canada’s boreal forest, with annual totals more than quadrupling compared to the period before 1970.
These changes correlate well with the global warming after 1975
Global warming should not be dismissed as a cause of the change in smoke affecting american cities
