Before Ottawa became Canada’s capital, it was Canada’s timber capital. The massive log booms floating down the Ottawa River, the roar of sawmills, and the wealth of lumber barons defined the region for decades. This industry built fortunes, attracted thousands of workers, and shaped the city’s character in ways still visible today.

The Ottawa timber trade created the economic foundation upon which the capital was built. Understanding this history explains much about how Ottawa developed.


Key Highlights

TL;DR: The Ottawa Valley timber trade dominated the region from the 1800s to early 1900s. Giant timber rafts floated down the Ottawa River to Quebec City for export to Britain. Lumber barons like J.R. Booth and E.B. Eddy built empires. The industry employed thousands but also brought violence and environmental damage.

The Birth of an Industry

Why Ottawa?

The Ottawa Valley was perfectly positioned for timber:

Natural Advantages:

  • Vast forests of white pine
  • Ottawa River provided transportation
  • Rapids powered sawmills
  • Access to British markets via St. Lawrence

The Trees:

  • White pine: tall, straight, strong
  • Perfect for ship masts and lumber
  • Some trees over 200 feet tall
  • Seemingly endless supply

Early Beginnings

The timber trade predated the canal:

Philemon Wright:

  • American settler who arrived 1800
  • First to raft timber to Quebec (1806)
  • Founded Hull (across from Ottawa)
  • Pioneer of the industry

Growth:

  • British demand for ship timber
  • Napoleonic Wars cut off Baltic supply
  • Canadian timber filled the gap
  • Industry exploded after 1810

How the Trade Worked

Harvesting

Timber cutting was winter work:

The Camps:

  • Remote forest locations
  • Men lived in rough shanties
  • Worked through brutal winters
  • Cut trees with axe and saw

The Workers:

  • French-Canadian habitants
  • Irish immigrants
  • Indigenous guides and workers
  • Seasonal employment

The Work:

  • Felling giant pines
  • Squaring timber with broadaxe
  • Hauling logs to waterways
  • Dangerous, exhausting labour

The River Drive

Spring brought the log drive:

The Process:

  • Snow melt floated logs downstream
  • Raftsmen guided timber
  • Logs assembled into massive rafts
  • Journey to Quebec could take weeks

The Dangers:

  • Log jams could be deadly
  • Cold water, fast rapids
  • Accidents common
  • Many men died in the drives

The Rafts

Timber rafts were remarkable:

Construction:

  • Logs bound together into “cribs”
  • Cribs assembled into larger rafts
  • Some rafts covered acres
  • Carried crews and supplies

Sliding the Chutes:

  • Chaudière Falls blocked navigation
  • Timber slides bypassed falls
  • Spectacular, dangerous descent
  • Essential infrastructure

The Lumber Barons

J.R. Booth

The greatest of Ottawa’s lumber kings:

Rise to Power:

  • Arrived in Ottawa 1852
  • Started with one mill
  • Built an empire
  • Became Canada’s wealthiest man

His Empire:

  • Controlled vast timber limits
  • Owned sawmills at Chaudière
  • Built his own railway (Canada Atlantic)
  • Employed thousands

Legacy:

  • Booth Street named for him
  • Booth family donated parkland
  • Defined Ottawa’s industrial era
  • Died 1925 at age 98

E.B. Eddy

Another industrial titan:

His Story:

  • Ezra Butler Eddy arrived 1851
  • Started making matches in Hull
  • Expanded into paper and lumber
  • Built massive industrial complex

The Eddy Company:

  • Major employer for generations
  • Matches, paper, lumber products
  • Survived the 1900 fire
  • Operated until 1998 (Domtar acquisition)

Others

More lumber barons shaped the region:

  • The Bronson family
  • The Perley family
  • The Edwards family
  • Multiple smaller operators

Impact on Ottawa

Economic Engine

Lumber drove Ottawa’s economy:

Employment:

  • Thousands worked in mills
  • More in camps and on drives
  • Supporting businesses thrived
  • Women worked in ancillary roles

Wealth:

  • Created local millionaires
  • Funded civic development
  • Built grand houses
  • Supported philanthropy

Social Consequences

The industry also brought problems:

The Shiners’ War:

  • Violent conflict 1830s-1840s
  • Irish vs. French-Canadian workers
  • Gang warfare in the streets
  • Murder and mayhem

Working Conditions:

  • Dangerous work
  • Poor pay for labourers
  • Seasonal unemployment
  • Limited worker protections

Inequality:

  • Vast gap between owners and workers
  • Barons lived in mansions
  • Workers in crowded housing
  • Class tensions persistent

The Chaudière District

Industrial Heart

Chaudière Falls powered the industry:

The Location:

  • Falls provided water power
  • Mills lined both shores
  • Hull and Ottawa sides developed
  • Industrial complex grew massive

What Was There:

  • Multiple sawmills
  • Paper mills later added
  • Match factories
  • Supporting industries

Danger and Disaster

The Chaudière was also dangerous:

Fire Risk:

  • Sawdust and wood everywhere
  • Mills burned repeatedly
  • Great Fire of 1900 started here
  • Constant threat

Pollution:

  • Sawdust choked the river
  • Smoke filled the air
  • No environmental regulations
  • Long-term damage

Decline of the Trade

Why It Ended

Several factors ended the timber boom:

Forest Depletion:

  • Best trees cut first
  • Had to go further for timber
  • Quality declined
  • Supply became difficult

Market Changes:

  • British demand decreased
  • American forests competed
  • Steel replaced wood in ships
  • New materials emerged

Transition:

  • Lumber gave way to pulp and paper
  • Sawmills converted or closed
  • Employment patterns changed
  • New industries emerged

What Replaced It

The region adapted:

  • Government employment grew
  • Service sector expanded
  • High-tech industry eventually arrived
  • Tourism developed

Legacy Today

What Remains

Traces of the timber era survive:

Chaudière Falls:

  • Now being redeveloped (Zibi)
  • Some historic structures preserved
  • Interpretive elements planned
  • Industrial heritage recognized

Street Names:

  • Booth Street
  • Bronson Avenue
  • Various roads named for lumber families

Museums:

  • Bytown Museum covers the era
  • Canadian Museum of History
  • Various interpretive sites

The timber trade lives in:

  • Local folklore and stories
  • Family histories
  • Historical photographs
  • Community identity

Frequently Asked Questions

Q: Can I see any original lumber mills? A: Most mills are gone, but the Chaudière area retains some industrial structures. The Zibi development is incorporating some heritage elements. Watson’s Mill in Manotick (a grist mill) gives a sense of 19th-century milling.

Q: Where did the lumber go? A: Most was exported to Britain via Quebec City. Some was processed locally for construction. As the industry evolved, pulp and paper products also shipped worldwide.

Q: How long did the log drives last? A: The spring log drive could take weeks, depending on water levels and distance. The last major Ottawa River log drive occurred in 1994, ending a centuries-old tradition.

Q: What happened to the lumber baron families? A: Many remained prominent. Some families continued in business, others became philanthropists. Streets, parks, and institutions bear their names throughout Ottawa.

Q: Was the timber trade environmentally destructive? A: Yes. Old-growth forests were devastated, river ecosystems damaged by sawdust and log drives, and air quality poor from mill operations. Environmental understanding was minimal in that era.


Final Thoughts

The Ottawa timber trade built this city—literally. The wealth generated by lumber funded construction, attracted workers, and created the economic base that helped Ottawa become a viable capital city.

But the timber era was also marked by exploitation: of forests cleared without thought for the future, of workers who labored in dangerous conditions for modest pay, of a river choked with sawdust and pollution. The contrast between the lumber barons’ mansions and their workers’ hovels reminds us that industrial prosperity has always been unevenly shared.

Today, as the Chaudière district transforms from industrial site to residential neighbourhood, Ottawa has a chance to honour this history while moving forward. The roar of sawmills has faded, but the Ottawa River still flows past where timber rafts once floated. And the city they helped build stands as the lasting legacy of the timber trade era.
