Why the St. Lawrence River's force makes waters dangerous and rescues complicated

Why the St. Lawrence River's force makes waters dangerous and rescues complicated

On a hot summer day, the St. Lawrence River can look calm, even inviting. Families set up picnics along the shore, people on paddleboards glide by, and some brave swimmers wade in to cool off.
Despite the city being surrounded by water, only a handful of places are considered safe for swimming.
Beneath a calm surface, Anastasia Polito, a Montreal-based triathlon coach, says there's a very real danger.
"It's moving at a quiet high speed," she said.
Even strong swimmers can be caught off guard by sudden currents or temperature changes, she says. Much of the river remains unpredictable — and its consequences can be fatal.
Last Wednesday, Montreal police recovered the body of a 32-year-old man who was last seen in the St. Lawrence River near Verdun Beach. In June, two other people died at the popular swimming spot. The recent drownings have prompted the borough to set up more signs to warn people about the risks of swimming outside the beach barriers and opening hours.

What makes the St. Lawrence River so dangerous for swimmers?
10 minutes ago
It's an important waterway in North America, but conditions in the St. Lawrence River can change rapidly and its size and force makes rescues complicated and dangerous for emergency responders.
Stretching 1,200 kilometres, the St. Lawrence River is one of North America's great waterways. It links the Great Lakes to the Atlantic, carrying massive cargo ships through its deep channels.
Those same channels create swirling currents that can change in seconds.
Along with sudden drops in temperature and few monitored swimming areas, experts say the size and force of the river also make rescues complicated and dangerous for emergency responders.
'Minutes to intervene,' says president of firefighters association
Chris Ross, president of the Montreal Firefighters Association, says even with access to a phone and a call to 911, help might not arrive in time.
"We're not trained or equipped to perform rescues from sides of the river," says Ross.
"Our water rescues are boat-based. That means we need time to get to the boat."
By the time crews get in the water and reach the person in distress, he says they might run out of time.
"If you want to save somebody's life that's in the process of drowning, you have literally minutes to intervene and get them out of the water," he said.
Experts stress that the best way to stay safe is to know your limits, avoid swimming alone, wear a life jacket, check local water quality advisories and choose supervised swimming areas.
In Montreal, there are a few designated swimming areas including Verdun Beach, Parc Jean-Doré Beach, and Cap-Saint-Jacques. While these sites are monitored by lifeguards, and their water quality regularly tested, the rest of the river is largely unmonitored.
Warning signs are few and far between, and conditions can change in minutes. What might look like a quiet, welcoming stretch of water may hide invisible hazards, experts say.
"Each part of the river has its own characteristics," says Jeff Ridal, executive director of the St. Lawrence River Institute.

Bay and Algoma Buskers Festival marks 10th year

While some intense weather caused some concern over the weekend, the 2025 Bay and Algoma Buskers Festival was a success, organizers said. The 10th annual festival ran Saturday and Sunday in the Bay and Algoma neighbourhood. It featured various food and merchandise vendors, and performers from Thunder Bay, and around the world, including: Steve Goodtime Seb and Fritzzz Fraser Hooper Skye the Guy Kasmir the Hungry The Kidd Creed Statuary Women in Silk Taiko Drummers Phineas Gauge, and the Bay Street Bastards. Things got underway later than planned on Sunday, due to a heavy downpour that hit the city late in the morning, said Uriel Lubuk, one of the event's coordinators. "It was awesome to see a lot of the arts and culture community come out," he said. "Awesome vendors, lots of smiley faces, lots of kids." "We've always wanted free family fun," Lubuk said. "People come down, tip the buskers, see something new and amazing that they haven't seen before." One of the local buskers was Zachary Ross, who performed both Saturday and Sunday. "I've started learning how to do folk music," he said. "I host open mics at Lakehead Beer Company, and yeah, just love the community and love going out to play." "I think it's a great time," he said of the festival. "I love seeing everyone out here." Lubuk said organizers are already turning their attention to next year's buskers festival "and just seeing how we could push through, do a little bit better next year, but just keep the vibes the same."

Over 1,000 participants swim, cycle and run at Ironman 70.3 west of Calgary

Over 1,000 competitors swam, cycled and ran at Ironman 70.3 Sunday at Lake Harmony, west of the city. It might have been a little wet and chilly for the folkies on Sunday, but the weather was just right for the competitors in the Ironman 70.3. Over one thousand people from around the world swam, cycled and ran Sunday at Lake Harmony, west of Calgary. For event organizer Tom Bamford, it couldn't have been nicer. 'We're thrilled to be at the community here, just west of Calgary,' he said. 'Lake Harmony is a great venue, because we have open highways, we have vistas of the Rocky Mountains, (and) a beautiful lake to swim in.' 'We've got 1,100 athletes from around the world, (from) 16 countries,' he added, 'and it's a world championship qualifying race for (the Ironman event in) Nice, France next year.' Bamford said being a world championship qualifying race is significant. 'Well, the race is part of a global series of Ironman events,' he said. 'The 70.3 level is a certain distance, and it has a world championships that athletes can qualify for -- 30 men, 30 women in their own age groups can qualify for the world championships. Tom Bamford, July 27, 2025 Tom Bamford is the race manager of Ironman 70.3, which took place Sunday at Lake Harmony west of Calgary. (Tyson Fedor, CTV Calgary) 'We also have hundreds of other athletes,' he added, 'that just really want to get the distance done. And we have relay teams too, enjoying the day.' He said the wet, chilly weather conditions Sunday made for a tough cycle but by the time participants get to the running portion of the race, they feel better. 'When you're on the bicycle and the wind and the rain (come down), it is a challenging experience, and we're doing some modifications on the course just to make sure everybody gets home safe and sound,' he said. 'But once they hit the run, they start warming up, they get the blood flowing down to the feet -- and everybody kind of is in a better position, and they look forward to that finish line.'
