Voyageurs Highway 1750: From Lachine to Michilimackinac

 

Imagine setting out in the spring of 1750, as a voyageur in the service of the French fur trade, embarking from Lachine near Montreal in a birch bark canot du maître—a sturdy vessel some 36 feet long, crafted from white birch, cedar, and spruce roots, capable of carrying up to 65 packs of trade goods and furs, weighing around 3 tons when loaded. Your crew of 8 to 10 hardy men, clad in simple wool shirts, leggings, and moccasins, paddles in unison, singing rhythmic chansons to keep the pace. The air is crisp, the rivers swollen from snowmelt, and the goal is Michilimackinac, the bustling fort at the straits where Lakes Huron and Michigan meet, a key hub for trade with the Ojibwe, Ottawa, and other Indigenous nations.

The journey begins up the Ottawa River, a vital artery of the fur trade avoiding the treacherous Niagara route.  Leaving the St. Lawrence behind, you paddle against the current for hundreds of miles, navigating through dense forests of pine and hardwood. The Ottawa is a beast—clustered with rapids and falls that demand frequent portages. At places like the Chaudière Falls or Long Sault, you unload the canoe, shoulder heavy packs (90 pounds each, often two at a time in the "double carry"), and trek over rocky paths, sometimes for miles. Mosquitoes swarm in the blackfly season, and rain turns trails to mud, but the river's beauty shines: wide stretches of calm water reflect the Laurentian hills, and you camp on sandy banks, cooking pemmican or fresh game over fires.  Indigenous guides, perhaps from Algonquin bands, share knowledge of the waters, trading for beads or knives along the way. This leg alone might take two to three weeks, pushing 14-hour days.

Reaching the Mattawa River, a tributary about 40 miles long, the terrain grows rugged and wild—rocky gorges and swift currents with little settlement, even in 1750.  It's a "little gem of history," as later accounts describe, with clustered portages over granite ridges and bogs. You haul the canoe upstream, portaging around falls like the Paresseux or Talon, sweat-soaked and chanting to maintain morale. The Mattawa's tight, twisting path demands skill; overhanging branches snag at the bark hull, but repairs are quick with pine gum and spare birch sheets. Wildlife abounds—moose, bear, and beaver—and the nights are alive with wolves' howls. After several grueling days, you reach Trout Lake, then cross the height-of-land divide via the La Vase portages: a series of seven miles over ridges and beaver-dammed ponds, where the canoe glides through narrow, muddy creeks.  Beaver dams here are a boon, turning trickles into navigable channels, though trapping has thinned their numbers by mid-century.

Emerging onto Lake Nipissing, a shallow, island-dotted expanse, you feel relief. But beware the winds—its choppy waters can whip up dangerous waves, so you hug the southern shore for safety.  Crossing takes a day or two, with camps on rocky islets. From Nipissing's western outlet, you descend the French River, a 70-mile downstream run that's a voyageur's delight in high water.  Following the south channel, you shoot rapids with exhilarating speed, portaging only at Recollet Falls and Petite Faucille—short carries of 50 paces or so. The river carves through pink granite of the Canadian Shield, with pines clinging to cliffs and clear pools teeming with fish. It's a swift day's paddle, ending as the French empties into Georgian Bay on Lake Huron.

Now on the vast, temperamental Lake Huron, you skirt the northern shore of Georgian Bay, navigating among the 30,000 Islands—rocky archipelagos sacred to Anishinaabe peoples.  Storms can arise suddenly, so you watch the skies and seek shelter in coves. Paddling westward, past Manitoulin Island, the lake's scale dwarfs your canoe; waves crash against the hull, and you bail furiously during squalls. This final stretch covers hundreds of miles, taking one to two weeks, with stops at trading posts or Indigenous villages for resupply. Finally, the Straits of Mackinac appear, and you arrive at Fort Michilimackinac—a palisaded outpost buzzing with traders, soldiers, and Native allies.  Here, you unload furs from the pays d'en haut, barter for beaver pelts, and perhaps winter over or turn back for Montreal before ice sets in.

This route, the "first Trans-Canada Highway," was the lifeblood of the fur trade, forging alliances and mapping the continent.  It's a test of endurance—portages numbering in the dozens, endless paddling at 50 strokes per minute—but the camaraderie, wilderness splendor, and promise of profit make it legendary. In total, the 1,000-mile voyage might span a month or more, weather permitting, etching memories of a raw, untamed New France.

More Notes (from Gemini AI):

The historic voyageur route from Lachine to Michilimackinac via the Ottawa River was a grueling 650-mile (1,050 km) journey known as the "northern route". It served as the primary highway for the North West Company's heavy freight canoes (canots du maître). 

Phase 1: The Ottawa River (Upstream)

After receiving their blessing at Sainte-Anne-de-Bellevue, the brigades faced their first major challenge: paddling against the powerful current of the Ottawa River. 

• The Long Sault Rapids: One of the most difficult early stretches, requiring exhausting portages or "lining" (pulling canoes with ropes) through the white water.
• Rideau & Chaudière Falls: Near modern-day Ottawa, voyageurs had to portage around these massive cataracts.
• Mattawa "The Forks": The route turned west at the junction of the Ottawa and Mattawa Rivers. This section was particularly arduous, with 11 port

Phase 2: The Height of Land

At the headwaters of the Mattawa, the crew reached a critical geographical divide.

• Trout Lake & La Vase Portages: Voyageurs carried their 2,300 kg loads over the "Height of Land". This 7-mile (11 km) series of muddy portages led them from the Atlantic-directed watershed into the Great Lakes basin. 

Phase 3: Lake Nipissing to Georgian Bay (Downstream)

The transition to the Great Lakes drainage offered a brief reprieve with downstream paddling.

• Lake Nipissing: A large, shallow lake that could be dangerous during sudden summer storms.
• The French River: This 70-mile (110 km) stretch provided "easy" downstream paddling through scenic granite channels before emptying into Georgian Bay.

Phase 4: Lake Huron to Michilimackinac

The final leg required navigating the open waters of the upper Great Lakes.

• The North Channel: To avoid the treacherous open waters of Lake Huron, voyageurs typically hugged the northern shore, traveling behind Manitoulin Island.
• Arrival at Michilimackinac: The journey concluded at the Straits of Mackinac, the central hub where Lake Huron meets Lake Michigan. This was the primary summer depot for exchanging trade goods from Montreal for furs from the "Northwest". 

The entire trip typically took about 4 to 6 weeks, with crews paddling up to 14–18 hours a day.
