Drug warning: August 11, 2025

Public Health Sudbury & Districts is warning of a rise in drug poisonings (overdoses) and unexpected reactions to substances in the Sudbury and Manitoulin districts.

The cause of the increase is unknown. This serves as an important reminder that street drugs may be cut or mixed with substances such as benzos (benzodiazepines), xylazine, medetomidine, fentanyl, or carfentanil. Be cautious if using drugs and please share this information widely to help save lives.

Key information

A pink rock-like substance is reportedly being sold as fentanyl. Taking this substance is also reported to cause prolonged sedation (heavy nods). Due to concerns about benzodiazepines (benzos) and tranquilizers (xylazine and medetomidine), take steps to support someone who is sedated.

How to prevent poisonings

A poisoning occurs when a person uses a substance, and their body cannot handle its effects. A person can pass out, stop breathing, or experience a seizure. Poisonings can be fatal or non-fatal.

How to respond to poisonings

How to recognize poisonings

Different substances affect the body in different ways. Depending on the type of substance consumed, symptoms of a poisoning may look different.

Heat warning extended: August 11, 2025

Heat warning extended for the following locations:

The heat warning, which began Saturday, August 9, 2025, is being extended given the hot, humid weather in the forecast. Heat warnings are extended while the weather stays at 29 degrees Celsius or above during the day and 18 degrees Celsius or above at night, or the humidex reaches 36 or above.

“Frequently check on your friends, neighbours, and relatives, especially if they are at higher risk of heat-related illness to ensure that they are staying cool and hydrated,” said Burgess Hawkins, a manager with Public Health Sudbury & Districts’ Health Protection Division.

Continuous exposure to high levels of heat can lead to dehydration and illnesses such as heat stroke, heat exhaustion, heat fainting, heat edema (swelling of hands, feet and ankles), heat rash, heat cramps (muscle cramps), and even death. People who are at higher risk include, older adults, infants and young children, pregnant women, people with chronic illnesses, people who are homeless, people who use alcohol or illicit drugs, and those who work or exercise in the heat. Those who take medications or have a health condition should consult their doctor or pharmacist to determine if they are at increased risk from the heat and follow their recommendations.

Symptoms of heat-related illness include dizziness or fainting, nausea or vomiting, headache, rapid breathing and heartbeat, extreme thirst, and decreased urination with unusually dark yellow urine. If you or someone in your care experiences these symptoms, contact a health care professional. In emergencies, call 911.

Take precautions and stay cool during this time of high temperatures. Take a break from the heat by spending a few hours in a cool place, for example, in a tree-shaded area, swimming facility, or an air-conditioned public building such as a shopping mall, grocery store, place of worship, public library, or home of a family member or friend. Drink plenty of cool liquids, especially water, before you feel thirsty to decrease your risk of dehydration. Avoid sun exposure by shading yourself by wearing a wide-brimmed, breathable hat or using an umbrella, and wearing loose-fitting, light-coloured clothing made of breathable fabric.

Public Health Sudbury & Districts offers information on beating the heat in apartment buildings, keeping your pets safe, doing outdoor activities in heat and smog, and keeping your children safe during hot weather.

Public Health Sudbury & Districts continues a thorough investigation into recent measles infection

Additional infections and community exposures identified

Since Public Health Sudbury & Districts reported a measles infection on Tuesday, July 22, it has been investigating the source of that measles infection and identifying other transmission that has occurred in order to prevent further spread.

Through the efforts of that investigation, Public Health has identified an initial, previously undetected introduction of measles into the area 7 weeks ago. That infection is linked to the broader measles outbreak occurring throughout North America. Through following chains of transmission from that initial infection to the one reported earlier this week, Public Health has uncovered an additional 39 measles infections in its service area. The majority of these infections have now resolved.

Public Health has identified numerous private gatherings and interactions that have led to infection spreading to these individuals. In addition, Public Health has identified some recent public locations where members of the general public may have been exposed to measles. These are listed below. Public Health is continuing its investigation by contacting individuals who were previously ill or who have been exposed to persons infected with measles.

“Over 95% of measles infections in Ontario have not been fully vaccinated; the overwhelming majority of infections we are seeing locally align with that trend,” said Dr. M. Mustafa Hirji, Acting Medical Officer of Health for Public Health Sudbury & Districts. “Since measles can cause severe illness, disability, or even death in some people, I encourage everyone to ensure they have had two doses of the measles, mumps, and rubella vaccine,” said Dr. Hirji.

Important instructions:

  1. Review the locations, dates, and times below to determine if you may have been exposed to measles.
  2. Check your immunization records.
  3. Learn whether to contact your health care provider or Public Health.
  4. Monitor for symptoms.

Step 1. Review the exposure locations, dates, and times

The measles virus can spread through the air or direct contact with an infected person. The virus can live for up to 2 hours in the air or on surfaces.

Recent exposure locations:

Older exposures

People who were exposed on the dates listed below would have already developed illness if they were infected. Follow up with your health care provider if you have any questions or were previously ill with symptoms that could have been measles (as outlined below).

Step 2: Learn how to check your immunization records

If you were exposed, are fully vaccinated, and DO NOT fit into any of the groups of people listed in Step 3 (below), monitor yourself for symptoms for 21 days past your exposure.

Step 3: If you were exposed to measles, learn when to contact your health care provider or Public Health

Contact your health care provider as soon as possible to discuss vaccination if

By receiving a vaccine soon after an exposure, you can help protect yourself and your child from infection.

Contact Public Health Sudbury & Districts as soon as possible to discuss receiving immune globulin if

If you or your child are eligible to receive immune globulin, Public Health will coordinate a request with the hospital. Immune globulin can help protect against infection.

Call Public Health at 705.522.9200, ext. 772 (toll-free 1.866.522.9200), Monday to Friday, 8:30 a.m. to 4:30 p.m., or after hours and on weekends at 705.688.4366.

Step 4: Monitor for symptoms

Monitor yourself for symptoms for 21 days past the date of your last exposure.

If you develop symptoms:

Vaccination remains the best protection against measles—it’s safe and effective. Measles can lead to serious complications such as lung infections, swelling of the brain, seizures, and middle ear infections, and in rare cases, death.

Public Health Ontario posts detailed information about measles cases in Ontario in a weekly summary. For more information about measles, immunization, or exposures, please visit phsd.ca or call Public Health Sudbury & Districts at 705.522.9200 (toll-free 1.866.522.9200).

Protect yourself from wildfire smoke

Environment and Climate Change Canada has issued an air quality statement for

According to Environment and Climate Change Canada (Government of Canada), smoke from wildfires (forest fires) is affecting air quality. Public Health Sudbury & Districts would like to remind residents of the health effects of wildfire smoke and how to protect yourself.

Different people can have very different reactions to the same amount of smoke. Those more likely to experience symptoms from wildfire smoke include older adults, people who smoke, pregnant people, infants and young children, people who do strenuous outdoor work or exercise, and people with existing health conditions, such as cancer, diabetes, respiratory, or heart conditions.

“Mild symptoms from wildfire smoke can usually be treated at home and may include a mild cough, headache, and eye, nose, or throat irritation,” said Jane Mantyla, a health promoter with Public Health Sudbury & Districts’ Health Protection Division.

“If you have more severe symptoms, talk to a health care provider. You can also call or chat online with a registered nurse day or night for free, secure, and confidential health advice by contacting Health811—visit health811.ontario.ca (Ontario Government), or call 811 (TTY 1.866.797.0007). In an emergency, call 911. Watch out for severe cough, wheezing, difficulty breathing, asthma attacks, dizziness, chest pain, and irregular heartbeat,” said Mantyla.

The best way to protect your health is to reduce your exposure to wildfire smoke. You can do this by limiting outdoor and strenuous physical activities, staying indoors with windows and doors closed, and using a portable air purifier (Government of Canada). If you must spend time outdoors, a well-fitted respirator type mask, such as a NIOSH-certified N95 or equivalent respirator (which does not allow air to pass through small openings between the mask and face), may help reduce your exposure to the fine particles in smoke. If you feel unwell or have difficulty breathing, stop outdoor activities altogether.

Other precautions to take:

Air quality conditions can change rapidly. For more information, check the Air Quality Health Index (AQHI) (Ontario Government), visit www.phsd.ca, or call Public Health Sudbury & Districts at 705.522.9200, ext. 464 (toll-free 1.866.522.9200) to speak to a public health inspector.

Drinking water advisory issued for parts of the Town of Mindemoya including Douglas Street, Yonge Street (south of Douglas), King Street, and areas south of King Street

Public Health Sudbury & Districts has issued a drinking water advisory effective immediately for all residents of the Town of Mindemoya who get their water from the Mindemoya water treatment system on Douglas Street, Yonge Street south of Douglas Street, King Street, and areas south of King Street.

A drinking water advisory means that people who take their water from the municipal system should NOT use it for drinking; making juice, infant formula, or ice; cooking; washing uncooked fruit and vegetables; or brushing teeth. Boiling the water may not make it safe for drinking. For these purposes, water from an alternate source, such as bottled water, should be used. The water can be used for laundry and bathing (excluding small children who could swallow the water).

The town advises that residents can bring and fill their own containers at the nearest water filling station located at the town’s water treatment plant located at 61 Old Hwy 551, Mindemoya.

Although the town has re-established the water supply, which was interrupted due to a loss of pressure, residents should not use the water for human consumption until advised otherwise by Public Health Sudbury & Districts.

“It is possible that the loss of water pressure created conditions that compromised the safety of the drinking water,” said Burgess Hawkins, a manager in Public Health’s Health Protection Division. “Until bacteriological testing of the drinking water indicates a safe supply, the drinking water advisory will remain in effect as a precaution.”

Public Health staff will continue to monitor the situation. Public Health Sudbury & Districts will notify the municipality when the drinking water advisory is lifted and residents will be advised.

For more information, please call Public Health Sudbury & Districts at 705.522.9200, ext. 398 (toll-free 1.866.522.9200) or visit phsd.ca.

Drug warning: Increase in suspected drug poisonings (overdoses)

The Community Drug Strategies have received reports of an increase in the number of drug poisonings (overdoses) with heavy and prolonged sedation and unexpected reactions from the use of substances in the Sudbury and districts area.

While we cannot identify the substance(s) causing the poisonings, this situation serves as an important reminder to the community that street drugs may be cut or mixed with substances such as benzos (benzodiazepines), xylazine, medetomidine, fentanyl, or carfentanil. Frontline workers warn that more toxic substances may be circulating locally.

A poisoning occurs when a person uses a substance and their body is unable to handle the effects. As a result, the brain is unable to control basic life functions. The person might pass out, stop breathing, or experience a seizure. Poisonings can be fatal and non-fatal.

Prevent poisonings to save lives:

Board of Health for Public Health Sudbury & Districts votes in favour of merging with Algoma Public Health

Today the Board of Health for Public Health Sudbury & Districts met to consider and vote on a motion to merge with Algoma Public Health (APH). Following careful review and intense deliberations, Board members voted unanimously in favour of developing a joint business case to propose to the Ministry of Health a merger of the two public health agencies. Earlier in the day, however, the Board of Health for APH voted against a merger with Public Health Sudbury & Districts.

“Today’s Public Health Sudbury & Districts deliberations were in response to the Ministry of Health’s August 2023 announcement encouraging voluntary mergers and providing merger support funding for public health units. On behalf of Board members, I would like to extend our gratitude for the thoughtful and extensive work by both boards of health, the Medical Officers of Health, and staff from both public health units over the last few months to gather the information necessary to make an informed decision,” said René Lapierre, Chair, Board of Health for Public Health Sudbury & Districts.

“Throughout the process, the Board has been committed to ensuring a responsive, local public health service so we can respond to the health issues of today and the unexpected surges in demand of tomorrow. While our respective boards have decided differently, the diversity of perspectives shared during this exploration has enriched our relationships and mutual understanding,” said Lapierre.

Proposing a potential merger to the Ministry of Health requires agreement from both boards of health. As the Board of Health for Public Health Sudbury & Districts voted to support the potential merger and the Board of Health for Algoma Public Health voted against, a merger proposal will not be submitted to the Ministry.

“Our health system is under considerable strain, and we know that it’s critical to invest in a strong public health system to keep us healthy—from kids to seniors and from oral health to safe drinking water. We have longstanding and excellent relationships with Algoma Public Health—from frontline staff to senior leadership—and I know that both agencies remain committed to acting in the best interests of local communities to achieve the health equity that our areas deserve,” said Dr. Penny Sutcliffe, Medical Officer of Health and Chief Executive Officer for Public Health Sudbury & Districts. “Today’s decisions mean that our existing relationships continue and we look forward to future collaborations in support of local public health,” said Dr. Sutcliffe.

Following direction from the Board of Health in November 2023, staff and Board members from Public Health Sudbury & Districts engaged with Algoma Public Health in a feasibility study funded by the Ministry of Health. The study gathered information and explored the merits and risks of a merger with Algoma Public Health. Today’s Public Health Sudbury & Districts Board of Health decision was informed by this comprehensive study and the Board’s assessment of the potential impact of a merger on the agency’s ability to deliver public health programs and services to area communities.

The Board of Health will continue to seek to build on the agency’s nearly 70 years of delivering public health programs and services, developing pivotal community connections, and working with partners to improve opportunities for health for all. Skilled public health professionals and stable leadership have been cornerstones to the agency’s effectiveness, and its commitment to evidence informed practice will remain a primary focus in the future.

Board of Health members are committed to improving opportunities for health and creating healthier communities for all. Proceedings (agendas, minutes, and motions) for the Board are available online. To learn more about local public health programs and services, please contact Public Health Sudbury & Districts at 705.522.9200 (toll-free 1.866.522.9200) or visit www.phsd.ca.
