Asbestos worries cause some Ottawa tennis clubs to close clay courts
The Elmdale Tennis Club and Tennis Centre West Ottawa (TCWO) have both closed their Har-Tru clay courts until the results return, while the Ottawa Tennis Club and the Rideau Sports Centre are keeping their clay courts open.
Last week, some Quebec municipalities shut their clay courts down after an analysis found above-standard asbestos concentrations in the products used to maintain them.
Saint-Sauveur, Que., found samples taken from clay produced by an American company, Har-Tru, had an asbestos concentration of at least one per cent — 10 times the concentration allowed by Quebec standards.
Samples taken from an actual municipal court surface, however, had no traces of asbestos.
Tennis clubs in Ottawa became aware of the issue during the week.
Chris Cobb, the secretary and spokesperson for Elmdale Tennis Club, said they spoke with other clubs before calling an emergency board meeting Friday night.
They then decided to close their courts around 7:30 p.m.
"Obviously we hope that the results are negative. But we do have children's camps, summer camps. And we have staff to consider — they're there for long shifts, and they maintain the courts," Cobb said.
"It just all made sense to close down, just for a few days."
Elmdale, which only has Har-Tru clay courts, told members by email that "out of an abundance of caution" they were closing so they could have their bagged clay supply and the court surfaces tested.
"The clay testing company took samples from the club [Saturday] morning," another email said. "The company tells us they should have the testing results back to us by Monday or Tuesday."
CBC reached the front desk at TCWO and the Rideau Sports Centre on Saturday, both of which confirmed they were aware of a potential asbestos contamination.
The TCWO said their Har-Tru courts were closed but their indoor red clay courts, which have not been recently linked with asbestos contamination, remain open.
Elmdale also said it was told by their Canadian supplier that Har-Tru anticipates a temporary hold on the import, sale, and use of its materials in Quebec and possibly other parts of Canada.
Made from natural green stone
Unlike red-clay, Har-Tru is made from a natural green stone that's extremely hard and angular. It's then crushed, screened, and mixed in the precise proportions necessary to produce a consistent playing surface, according to the company's website.
CBC emailed both clubs for an official statement but did not get one in time for publication.
The Ottawa Tennis Club declined to comment but sent CBC the statement club members got Friday. It said they'd been in daily contact with Ottawa Public Health (OPS) and there is no evidence that materials on their Har-Tru court are "non-compliant."
It also said stored and surface clay was sampled and sent for testing Wednesday morning, with results expected early this week.
"According to the information available we have currently, the reported non-compliant test results from the tennis club in Quebec pertained to raw product samples prior to application, not from material already installed on courts," the statement said.
"If at any time new information comes to light that may influence our decision to remain open we will immediately re-evaluate."
The club has also taken precautionary measures like watering more and adding extra calcium to the court, which can act as a binding agent for asbestos.
No reason to panic, says expert
The risk of contracting mesothelioma — a form of cancer linked to the inhalation of asbestos fibres — increases tenfold after even the slightest exposure to the fibres, according to Norman King, epidemiologist and scientific advisor for the Quebec Association for Asbestos Victims.
He told CBC the closures are no reason to panic.
"If we say that the risk is 10 times greater in someone slightly exposed, it is still a rare disease, it is one case per 100,000 people exposed," he said.
In its own statement Saturday, OPH said they'd been in touch with local tennis clubs for consultations about clay courts.
The health unit said they were working with the clubs and "other provincial bodies" to investigate the situation further, and had no additional information as of late Saturday afternoon to share.

The Push to Diagnose MS Years Before Symptoms Start
Aug. 13, 2025 – What if a blood test could flag multiple sclerosis years before symptoms start? Amid recent breakthroughs in diagnosis and treatment – like advanced MRI techniques and powerful B-cell depletion therapies – scientists say the next frontier in MS care could be prevention. They believe they're on the path toward being able to identify the disease before full symptoms appear, during what's known as the "prodromal" phase. This could give doctors a chance to intervene in the teenage or early adulthood years, potentially preventing a condition that can lead to serious disability or neurological decline. Although it would be many years before such a test becomes available, scientists are laying the groundwork now. Canadian researchers recently analyzed health care visit patterns for more than 10,000 people over 25 years and found that those who eventually developed MS had a clear pattern of doctor visits that differs from those of the general population. Among the findings: A dozen years before their MS diagnosis, patients visited psychiatrists at more than double the rate, compared with people of the same age, gender, and geographic region who did not go on to be diagnosed with MS. What that means, said senior author Helen Tremlett, PhD, is that "people were already changing" during their early to mid-20s, since the average age of the start of MS in the study was 37. A Pattern Stretching Back 15 Years The pattern of health care visits revealed in the study aligns with existing knowledge about early MS symptoms, which include the kind of nondescript health issues – like pain, fatigue, headache, dizziness, anxiety, and depression – that can be challenging for doctors to diagnose. Particularly striking was just how many years before MS onset the pattern of doctor's visits started: 15 years: A decade-and-a-half before clear symptoms developed, people who would eventually develop MS had a 19% higher rate of visits to a general practice doctor, and they were more likely to have doctor visits for "ill-defined symptoms" like fatigue or pain. 12 to 14 years: Mental health visits were markedly higher at 14 years before diagnosis, with a rise in psychiatric visits starting at 12 years and escalating after that. 8 to 9 years: Eye pain and blurry vision are common MS symptoms, and people eventually diagnosed were more likely to seek neurology and ophthalmology care starting eight to nine years earlier. 3 to 5 years: Emergency room visits and radiology visits for medical imaging were higher than those of the general population starting around three to five years before diagnosis. 1 year: The year before an MS diagnosis, doctor visits across specialties peaked. Tremlett, a professor at the University of British Columbia in Vancouver, Canada, cautioned that MS is still uncommon, affecting about 1 million people in the U.S. "The vast majority of people who visit a doctor for the issues we identified do not develop MS and will not develop MS," she said. "No one should feel alarmed or concerned by our findings." Indeed, extra doctor visits for fatigue or pain are not reasons to get an MRI (magnetic resonance imaging) scan to check for MS-related brain lesions, and it's certainly not feasible to test everyone who frequently sees a psychiatrist for depression or anxiety. "We cannot use any of these findings – because they're too general – to accurately identify someone who goes on to develop MS. But I think it's really inspiring to think about: What else do we need? Where do we go to next?" Tremlett said, suggesting that perhaps one day, a person's age, gender, family history, and health care visit pattern could help identify whether they're at high risk. "But here's the key point," she added. "You need to include something more specific." What's really needed, she said, is a blood test. And Yale School of Medicine researchers in New Haven, Connecticut, are working on just such a test. Why a Blood Test for MS Is Not a Far-Fetched Idea Yale professor David Hafler, MD, has studied MS for nearly 50 years. His pivotal research, spanning five decades, identified MS as an autoimmune and genetic disease. A team at his lab is now studying people with a strong family history of MS – an effort that has tallied some 250 genetic variations that heighten risk – with the aim of developing a blood test. The key, Hafler said, is to monitor those who haven't yet had the Epstein-Barr virus (EBV) – an infection that usually doesn't have symptoms and spreads through saliva and body fluids; it infects about 90% of people by age 25. A groundbreaking 2022 study linked the virus to MS. Hafler suspects that in some people, EBV leads to breaking of "tolerance" – that is, it disrupts the immune system's ability to tolerate its own cells. This leads the body's autoreactive T cells to attack healthy cells. Tremlett's study fits the working model many scientists are using of a prodromal phase of MS, Hafler said. "What's happening is the disease is percolating," Hafler said. "I think there is a first stage before the T cells go into the brain, which is what leads to MS." He and his colleagues are watching for changes in blood samples of people being studied after EBV is first detected. The idea: "If someone starts to develop autoreactive T cells, for example, after an EBV infection, I would treat them with B-cell depletion," Hafler said, noting that much more research would be needed before taking that step. Even if a blood test were to be developed, it could raise ethical challenges. Some people have MS that isn't severe, or they have brain lesions identified on an MRI ordered for a different reason and they never go on to develop symptoms. In these scenarios, B-cell depletion treatment might not be worth the potential side effects, like a weakened immune system. Also on the horizon is genetic testing for MS. While not yet available outside of research trials, it's getting more accurate, Hafler said. Alongside those known 250 genetic variants, scientists are examining risk among people whose parents (one or both) have MS. "We haven't validated this yet, and it's not a test you can order," he said, "but the statistics tell us that if you're in the top 10 percentile [of carrying risk-associated genetic variants], you probably have a 1 in 10 chance of developing MS." With the latest research confirming the condition's long prodromal period, "the next step should be identifying patients at risk, and then to monitor them in the moment they show signs of developing MS biomarkers," Hafler said. What to Do if You're Worried About MS It's unlikely that someone with the health care visit patterns revealed in the recent study would be at risk of multiple sclerosis, said MS specialist Brittani Conway, MD, of the University of Minnesota. That said, she also encourages people to advocate for themselves if they think they are having early warning signs. "Trust your intuition," she said. "A lot of patients with MS do actually come to me with a bit of PTSD from their experience of being shuffled around the health care system." Perhaps, for someone who has a first-degree relative with MS, such a pattern or a sudden change could be worth a discussion with your doctor, Hafler said. Conway's advice is to "maintain that determination that there may be something off, even if it's not showing up right away." Also, remember that lifestyle changes – like eating healthy, exercising, and quitting smoking – are all key treatments for MS and for mood disorders, alike. "Focus on what is in your control," Conway said. "Focusing on lifestyle will be very helpful, and it's something that is within the power of the patient even before their diagnosis."

This Weather Network anchor was 'shocked' to learn she had osteoporosis after fracturing her ankle: 'Why wasn't I warned?'
Kim MacDonald, 56, says she didn't know that menopause can lead to bone density issues. Now she's warning other women to take their bone health seriously. In March 2025, Kim MacDonald, 56, was outside of her home in Hamilton, Ont. when she stumbled over an uneven sidewalk and rolled her ankle. Since she didn't fall and could still walk, she treated it as a run-of-the-mill twisted ankle. Despite icing and elevating it, the ankle began to swell. 'I still thought at that point, OK, worst case scenario, I sprained my ankle,' MacDonald told Yahoo Canada. 'And best case scenario, I just twisted it, and the swelling will go down soon enough.' The next day, the Weather Network anchor's foot was still quite swollen. She "hobbled" to the emergency room where an X-ray revealed that MacDonald's ankle wasn't sprained — it was broken. 'I was actually in shock," she said. "I thought, 'I didn't even do anything. How could this be broken?'' This article is for informational purposes only and is not a substitute for professional medical advice, diagnosis or treatment. Contact a qualified medical professional before engaging in any physical activity, or making any changes to your diet, medication or lifestyle. Because she injured herself in such a simple way, MacDonald's healthcare providers suggested a bone density test. Three weeks later, her general practitioner called her with some news: she had osteoporosis, a disease that causes bones to weaken and become porous. 'It was very upsetting,' she said. 'I thought that if I was to get osteoporosis, that would be something 20 years down the line. I didn't think I was going to get it at 56. I thought that's something you have when you're 76. So, I really didn't expect it. Why wasn't I warned?" Although commonly associated with advanced age, people can develop the disease at any point in their lifetime. According to Osteoporosis Canada, men and women begin to lose bone mass in their mid-30s, however, older women are more likely to be diagnosed with the disease. Of the more than two million people living with diagnosed osteoporosis, 80 per cent are women, according to Osteoporosis Canada, and at least one in three women will suffer from an osteoporotic fracture in their lifetime. Although hormones changes that impact bone health occur during perimenopause, post-menopausal women experience a significant drop in estrogen, which helps preserve bone density. Approximately 20 per cent of bone loss occurs during this phase of life. Back in 2017, MacDonald was diagnosed with breast cancer, and underwent chemotherapy and radiation. after her second round of treatment, the then-48-year-old was put into medical menopause. While MacDonald said she had an incredible health care team who saved her life, she was unaware of the impacts menopause would have on her bones. "Nobody said anything until after I broke my ankle, years later," she said. In June, MacDonald took to Instagram to share her osteoporosis diagnosis and help raise awareness for the realities of life after menopause. "Knowledge is power,' MacDonald said. 'And this is one of those things that you can stop from happening.' What is osteoporosis and why is it dangerous? In an interview with Yahoo Canada, Dr. Lindsay Sheriff, an obstetrician and gynecologist, said osteoporosis causes bones to become so "thin and brittle" that minor falls or simply performing everyday activities can result in a fracture. Like MacDonald, many women won't know they have the disease until a fracture occurs. Although commonly associated with advanced age, people can develop osteoporosis disease at any point in their lifetime. According to Osteoporosis Canada, men and women begin to lose bone mass in their mid-30s, however, older women are more likely to be diagnosed with the disease. Of the more than two million people living with diagnosed osteoporosis, 80 per cent are women, according to Osteoporosis Canada, and at least one in three women will suffer from an osteoporotic fracture in their lifetime. While most fractures can be treated, hip fractures in part hip fractures are a major concern, especially as you age. More than 20 per cent of women and 30 per cent of men who suffer a hip fracture will die within a year due to post-surgical complications like infection, blood clots and internal bleeding. What are the risk factors for osteoporosis? The steep decline in estrogen levels after menopause accelerate bone loss. 'This makes the perimenopausal and menopausal years a critical time for monitoring and protecting bone health,' Shirreff said. According to Osteoporosis Canada, 80 per cent of patients with a history of fractures are not given osteoporosis therapies. That means hundreds of thousands of Canadians suffer fractures every year due to undiagnosed, untreated osteoporosis. That's why it's important to be prepared and take precautionary measures. In Canada, routine bone density testing is recommended for all women and men aged 65 and older. However, Shirreff said younger people may be recommended for screening if they have various risk factors, including: Prolonged steroid use A history of fragility fractures (fractures that occur after a low-impact event like a fall from standing height) A family history of hip fractures Menopause before the age of 45 Smokers Have a high alcohol intake 'There are many circumstances where we would recommend earlier screening than the age of 65,' she said. 'It's important for you to individualize that discussion with your healthcare provider.' How to prevent and treat osteoporosis According to Shirreff, there are steps women can take in their 30s and 40s to help prevent osteoporosis. Opt for calcium and vitamin-D rich foods While calcium supplements can help prevent bone loss, you should be reaching for foods high in calcium and vitamin D like milk, cheese, yogurt beans, eggs salmon and tofu. Add weight-bearing and resistance-based exercises to your workout Weight-bearing exercises don't have to be complicated. Shireff said activities like walking, jogging or hiking, as well as stair climbing, tennis or pickleball can all benefit bone health as well as low-impact aerobics. Resistance training or strength training, like weight-lifting, squats, push-ups and lunges, is also important. 'Strength training is excellent for bone health, especially for the spine and the hip,' she said. Some women wear weighted vests while walking to strengthen muscles and improve endurance and cardio fitness. Formulate a plan with your doctor Women should also avoid smoking and consider limiting alcohol intake to help slow down bone loss. Shirreff said it's also a good idea to ask healthcare providers about a bone density tests, especially if you went into menopause at an early age. Together, you and your health provider can discuss whether hormone therapies, supplements or other medications would be beneficial. The good news is it's never too early to start incorporating these lifestyle and dietary habits. 'Estrogen levels go down the closer you get to menopause, so establishing healthy lifestyle and dietary habits early on — but especially during the perimenopausal time — can optimize bone health as you age,' Shirreff said.
