You’ve heard of traffic jams on gridlocked city streets or being stuck in a massive crowd after a concert or sporting event. But have you ever been stuck in a “bear jam?”
When a famous grizzly bear nicknamed “The Boss” wandered roadside in Banff National Park last summer, the result was a bear jam — lines and lines of cars and people hoping to catch a glimpse of the Canadian wildlife celebrity. In just one day, 1,422 vehicles lined the Bow Valley Parkway in an attempt to see the bear.
Documents obtained through "Access to Information" by the Rocky Mountain Outlook revealed that Parks Canada staff spent hours managing unruly and disrespectful crowds. The commotion highlighted the public fascination with The Boss and the difficulties park staff have with protecting wildlife.
The Banff Bear Jam That Stopped Traffic
On July 24, 2025, The Boss triggered one of Banff National Park’s largest wildlife traffic jams. Along the scenic Bow Valley Parkway, Parks Canada crews counted 1,422 vehicles, 66 cyclists, and 84 people outside of their vehicles during the multi-hour encounter.
And the chaos didn’t stop there. The following day, another famous grizzly known as Split Lip drew more than 300 vehicles in just one hour. Then, on July 26, The Boss returned again, prompting crews to manage another 965 vehicles, 16 cyclists, and 82 people standing outside.
For wildlife teams, scenes like these have become increasingly common. Banff National Park welcomed a record 4.5 million visitors in 2025, putting immense pressure on animals already navigating shrinking habitats and constant human presence.
As roadside ditches fill with spring grasses and dandelions — favorite snacks for hungry bears emerging from hibernation — more grizzlies are naturally drawn near roads. Yet despite repeated warnings, many visitors reportedly ignored instructions to remain inside their vehicles or move along safely.
Parks Canada workers suspect many visitors ignore the rules in hopes of capturing the perfect viral photo or video for social media, whatever the cost.

Who Is The Boss?
Believed to be in his mid-to-late twenties, The Boss, otherwise known as bear No. 122, is one of the oldest and largest grizzlies in Banff’s Bow Valley, weighing an estimated 295 to 317 kilograms (650 to 700 pounds), according to the CBC. Wildlife experts consider him the valley’s dominant bear, towering over rivals — like Split Lip — and CTV reported that he fathered roughly 75 percent of the cubs in the region.
He has also survived extraordinary odds, including two train collisions, helping cement his reputation as a symbol of resilience in the Canadian Rockies.
Each spring, wildlife watchers eagerly await his return, often making him one of the first bears spotted in Banff after hibernation. His massive size and survival story have turned him into a wildlife celebrity. But his fame has come with consequences.
Parks officials worry public fascination with The Boss is encouraging risky behavior, with visitors lingering too long on the roadside and inching too close to try and get the perfect photo.
Why Dangerous Wild Bear Encounters Rarely End Well
Research suggests noise and repeated disturbances from humans can create chronic stress for bears and disrupt their natural behaviors. A roadside bear may be protecting cubs, guarding a food source, or already be feeling overwhelmed due to the crowds. In these cases, people can be injured — or worse — if a stressed bear reacts.
However, in these situations, it is often the bear that suffers the harsher consequences. According to Rocky Mountain Outlook, if encounters escalate or bears become too comfortable around humans, they may become food-conditioned, associating people with snacks or garbage. Once that association happens, bears grow bolder and more aggressive, and are increasingly likely to return to the roadside.
And when bears and humans collide, bears are the ones who are relocated or even euthanized.
This makes the love and adoration for The Boss quite ironic, as the same public fascination that made him a celebrity could ultimately threaten his future.
