Before there was Ottawa, there was Bytown—a rugged frontier settlement carved from the wilderness along the Ottawa River. The story of Canada’s capital begins not with grand political ambitions, but with a military engineering project that would transform a remote forest outpost into a thriving city.
Understanding Bytown’s origins reveals the grit, determination, and strategic thinking that shaped modern Ottawa. This is the story of how a small construction camp became a nation’s capital.
Key Highlights
TL;DR: Bytown was founded in 1826 when Lieutenant-Colonel John By arrived to build the Rideau Canal. Named after its founder, the settlement grew from construction camp to bustling town, becoming Ottawa in 1855 and Canada’s capital in 1857.

The Arrival of Colonel By
A Military Mission
In 1826, Lieutenant-Colonel John By of the Royal Engineers arrived at the junction of the Ottawa, Rideau, and Gatineau rivers with a daunting mission: construct a 202-kilometre canal system connecting the Ottawa River to Lake Ontario.
Why the Canal?
The War of 1812 had exposed a critical vulnerability—the St. Lawrence River, Canada’s main supply route, ran dangerously close to American territory. British military planners needed an alternative route for troops and supplies, safely inland from potential American attack.
Setting Up Camp
Colonel By established his headquarters on the bluffs overlooking the Ottawa River, at what would become Parliament Hill. The location offered:
- Strategic high ground
- Access to the river for transport
- Proximity to the canal entrance
- Defensible terrain

The Building of Bytown
Workers Arrive
The canal project attracted thousands of workers:
- Irish immigrants fleeing famine
- French-Canadian labourers
- Scottish stonemasons
- English tradespeople
- Indigenous guides and workers
These men and their families needed housing, supplies, and services. Almost overnight, a town began to form.
Upper Town and Lower Town
Bytown quickly developed a class divide that would persist for decades:
Upper Town:
- Located on the bluffs near Colonel By’s headquarters
- Home to British officers, merchants, and professionals
- Stone and brick buildings
- Anglican church and genteel society
Lower Town:
- Clustered near the canal construction site
- Working-class Irish and French-Canadian labourers
- Wooden buildings and boarding houses
- Catholic churches and taverns
- Rougher, more chaotic atmosphere
The Canal Construction
From 1826 to 1832, workers blasted through rock, built locks, and dammed waterways. The conditions were brutal:
- Malaria killed hundreds in swampy areas
- Accidents claimed many lives
- Harsh winters halted work for months
- Living conditions were primitive
Despite the challenges, the Rideau Canal was completed in 1832—an engineering triumph that still operates today as a UNESCO World Heritage Site.
Growth and Growing Pains
The Timber Boom
Even as canal construction proceeded, Bytown found another economic engine: timber. The Ottawa River became a highway for massive log rafts heading to Quebec City and beyond.
Impact of the Timber Trade:
- Sawmills sprouted along the river
- Wealthy timber barons emerged
- Seasonal workers flooded the town
- Rough taverns multiplied
- Violence became common
The Shiners’ War
The 1830s brought violent conflict between Irish immigrants (called “Shiners” for their silk hats or perhaps bald heads from disease) and French-Canadian workers. Riots, murders, and gang warfare plagued Bytown for years.
This lawless period nearly destroyed the young settlement, but gradually, law and order prevailed as the town matured.

From Bytown to Ottawa
Incorporation as a Town
In 1850, Bytown was officially incorporated as a town, bringing formal governance and civic improvements. But residents soon felt the name “Bytown” lacked the dignity their growing community deserved.
The Name Change
In 1855, Bytown was renamed Ottawa and incorporated as a city. The new name derived from the Algonquin word “adawe,” meaning “to trade”—honouring the Indigenous peoples who had used this area as a trading hub for thousands of years.
Becoming the Capital
The greatest transformation came in 1857 when Queen Victoria selected Ottawa as the capital of the Province of Canada. This surprise choice—Ottawa was smaller and rougher than Montreal, Toronto, Quebec City, or Kingston—had strategic advantages:
- Distance from American border
- Location on the border between Upper and Lower Canada
- Less politically contentious than larger rivals
Legacy of Bytown
What Remains Today
Several traces of Bytown survive in modern Ottawa:
Bytown Museum:
- Located in Colonel By’s original commissariat building
- Ottawa’s oldest stone building
- Houses artifacts from the city’s earliest days
Street Names:
- By Ward (ByWard Market)
- Colonel By Drive
- Various street names honouring early settlers
The Rideau Canal:
- Still operational after nearly 200 years
- UNESCO World Heritage Site
- The reason Ottawa exists
The Bytown Character
Many say Ottawa retains traces of its Bytown character:
- Pragmatic rather than flashy
- Divided neighbourhoods with distinct personalities
- Strong sense of local history
- Resilient and adaptable
Frequently Asked Questions
Q: Why was it called Bytown? A: The settlement was named after Lieutenant-Colonel John By, the Royal Engineer who supervised construction of the Rideau Canal and effectively founded the community.
Q: When did Bytown become Ottawa? A: In 1855, when the town was incorporated as a city. The name “Ottawa” comes from the Algonquin word for “to trade.”
Q: How many people lived in early Bytown? A: Population reached about 1,000 by 1832 when the canal was completed, growing to approximately 7,500 by 1851.
Q: What happened to Colonel By? A: After completing the canal over budget, By was recalled to England for financial inquiry. Though cleared of wrongdoing, his career never recovered. He died in 1836, never knowing the city he founded would become Canada’s capital.
Q: Can you visit Bytown sites today? A: Yes! The Bytown Museum, the Rideau Canal locks, and the ByWard Market area all preserve the heritage of early Bytown.
Final Thoughts
The birth of Bytown represents a remarkable transformation—from wilderness construction camp to national capital in just over three decades. The determination of Colonel By, the labour of thousands of workers, and the entrepreneurial spirit of early settlers created the foundation for modern Ottawa.
Walking the streets of downtown Ottawa today, it’s worth remembering the rough-hewn settlement that once stood here. The elegant Parliament Buildings rose on the same bluffs where Colonel By pitched his tent. The ByWard Market bustles where labourers once brawled. And the Rideau Canal—the reason for it all—still flows through the heart of the city.
Bytown may be gone, but its spirit lives on in Canada’s capital.
