In March 2022, researchers in Ontario collared a young female grey wolf near Sault Ste. Marie. Within days she started walking east. She did not stop for four months. By the time Ruby reached Quebec's Laurentides Wildlife Reserve, she had covered 1,550 miles, including an 11-day wait at the Ottawa River before swimming across it at a point with no bridge and no dam.
The Algoma Highlands Conservancy had collared her in Prince Township as part of a study of wolf movement in the region. They named her Ruby. They were also tracking a local breeding female named Fifi, raising pups in an established territory nearby, whose movements stayed conventional throughout. Ruby's did not. The moment the collar started transmitting, it showed her leaving.
She headed north first, following the Lake Superior coast. Then she abruptly changed direction and turned east toward North Bay, covering roughly 310 miles in three weeks. A young female believed to be traveling alone, in unfamiliar country, averaging 15 miles a day through late-winter Ontario.
At North Bay she slowed. The Conservancy noted that her pause coincided with a brief snowfall followed by melt, conditions that make long-distance travel difficult and expensive for any animal. Ruby had no pack mate to break trail. Every mile of deep snow cost her more than it would cost a wolf in a group. She rested. She explored the North Bay area. She waited for conditions to improve.
Then she continued east to the Ottawa River.
She reached it on April 22. The Ottawa River in late April is cold, fast, and wide. Her movements suggested she meant to cross immediately. She did not. For 11 days she stayed near the river, moving along its banks, possibly scouting for a crossing where the current was weakest and the distance shortest. On roughly May 3, she chose a location with no bridge and no dam and swam across between 1,600 and 3,300 feet of flowing water. A solo swim across a major river in early May, with no pack waiting on the other side, is not a casual decision. Ruby made it.
On the Quebec side, she kept going. Her transmissions showed her moving into the Laurentides Wildlife Reserve, a 3,000-square-mile protected area of boreal forest north of Quebec City. Her easternmost reported position placed her roughly 620 miles from Prince Township in a straight line. The actual distance she had traveled on the ground, following shorelines, skirting lakes, crossing rivers, and detouring around obstacles, was approximately 1,550 miles in four months.
The Conservancy described her likely motivation as what biologists call dispersal: a young wolf leaving its natal area to find a mate and unoccupied territory. It is how populations stay connected and how animals avoid competition and inbreeding. It is also dangerous. A dispersing wolf faces unfamiliar country, roads, rivers, human development, and the constant cost of energy, usually without a pack.
Her collar came off in the Laurentides, which is what it was designed to do. The last position it sent placed her inside the reserve. Reading her final movements, the Conservancy's hypothesis is that she stopped traveling because she had found a pack and established herself there.
The route she left behind is now data. Algoma, North Bay, the Ottawa River, the forest north of Quebec City, one wolf's line across two provinces. The Conservancy is using it in its ecological corridors work to identify where those regions still connect.
