Staying Safe Outdoors This Summer in Toronto: Ticks, Sun, Heat, and More

Summer in Toronto is meant to be enjoyed. Between the trails through High Park, evenings at the Beaches, and weekends at the cottage, it is a season full of good reasons to be outside. A few simple precautions can help you enjoy all of it while avoiding the most common summer health hiccups, from sunburn to tick bites to overheating. None of this is meant to worry you. It is just good, practical knowledge for anyone spending time outdoors in and around the city this summer.

How can I protect myself from ticks in Toronto?

Ticks are increasingly common in and around Toronto, especially in grassy or wooded areas like ravines, parks, and trails. Most tick bites are harmless, but a small number of ticks in Ontario can carry Lyme disease, so it is worth knowing a few basics.

When you are heading into tall grass, wooded trails, or ravine paths, tucking your pants into your socks and wearing light-coloured clothing makes it easier to spot a tick before it attaches. Using an insect repellent that contains DEET or icaridin on exposed skin adds another layer of protection. After spending time outdoors, a quick tick check of your whole body, especially warm areas like behind the knees, the scalp, underarms, and the waistband, is a simple habit worth building into your evening routine.

If you do find a tick attached to your skin, removing it carefully and promptly with fine-tipped tweezers, pulling straight up without twisting, is the best approach. If you are unsure how to remove it safely, a pharmacist, walk-in clinic, or Health Connect Ontario at 811 can walk you through it. We go into more detail on tick safety and Lyme disease risk in Ontario in our companion article, since this topic deserves a closer look on its own.

How do I stay safe in the sun?

Toronto summers can bring some genuinely strong UV exposure, particularly between 11 a.m. and 3 p.m. when the sun is highest. A broad-spectrum sunscreen with at least SPF 30, applied generously and reapplied every couple of hours, especially after swimming or sweating, goes a long way. A hat, sunglasses, and lightweight long sleeves are helpful for longer stretches outdoors, like a day at the Toronto Islands or an afternoon at a Blue Jays game.

Sunburn is the most common outcome of too much sun, but it is worth watching for signs of heat-related illness as well, especially on the hottest days.

What should I know about heat safety?

On hot, humid Toronto days, especially those with a heat warning from Environment Canada, it is worth taking a few extra precautions. Staying hydrated throughout the day, not just when you feel thirsty, is one of the simplest and most effective things you can do. Taking breaks in shade or air conditioning, wearing breathable clothing, and avoiding strenuous outdoor activity during the hottest part of the afternoon can help you avoid feeling unwell.

Signs of heat exhaustion include heavy sweating, dizziness, headache, nausea, and feeling unusually tired. If you or someone with you starts to show these signs, moving to a cool place, sipping water, and resting are good first steps. If symptoms are severe or do not improve, such as confusion, a very high body temperature, or a loss of consciousness, this can be a medical emergency, and calling 911 is the right call.

The City of Toronto opens cooling centres and splash pads during extreme heat events, and many public libraries and community centres offer air-conditioned spaces that are open to everyone.

What about water safety at Toronto beaches?

Toronto has several beaches along the waterfront, including Woodbine Beach, Cherry Beach, and the Toronto Islands, that are popular in the summer months. Toronto Public Health monitors water quality at these beaches regularly and posts current swimming advisories, so it is worth checking before you head out, especially after heavy rain, which can temporarily affect water quality.

Basic water safety habits, like swimming within your ability, keeping an eye on children at all times near water, and being aware of posted flags or advisories, help keep beach days relaxed and enjoyable.

How do I deal with mosquito and insect bites?

Mosquitoes are a normal part of a Toronto summer, and most bites are simply itchy and go away on their own. Using an insect repellent, wearing long sleeves in the evening when mosquitoes are most active, and avoiding standing water near your home, which is where mosquitoes breed, can reduce how often you get bitten.

Very occasionally, mosquitoes in Ontario can carry West Nile virus, though the overall risk remains low. If you develop a fever, headache, or body aches after a mosquito bite, especially if symptoms feel unusual or do not improve, it is worth checking in with a healthcare provider.

What if I come into contact with poison ivy?

Poison ivy grows in wooded areas and along some trails around Toronto, including parts of the ravine system. It can cause an itchy, sometimes blistering rash if your skin comes into contact with its oils. Learning to recognize its distinct three-leaf pattern is the best form of prevention, along with sticking to marked trails when hiking.

If you do come into contact with poison ivy, washing the area with soap and water as soon as possible can help reduce the reaction. A pharmacist can recommend something to ease the itching, and if the rash is widespread, involves your face or eyes, or does not improve, a walk-in clinic or your family doctor can help.

A note for parents and pet owners

If you are heading outdoors with kids or a family pet this summer, a few of these precautions are worth doing together. Kids tend to run through longer grass and wooded areas more than adults do, so a tick check after outdoor play is a good habit, along with sunscreen reapplied more often than you might think to reapply it yourself. Pets can pick up ticks too, particularly if they spend time in grassy or wooded areas, so checking your dog after a walk and speaking with your veterinarian about tick prevention products is worth considering. Children and pets are also more vulnerable to overheating than adults, so extra shade, extra water breaks, and avoiding the hottest part of the day are especially important for the smaller members of your household.

Quick summer safety tips

• Ticks: Wear light clothing, use repellent, and do a body check after time outdoors.
• Sun: Apply SPF 30 or higher and reapply often, especially midday.
• Heat: Stay hydrated, take shade breaks, and know the signs of heat exhaustion.
• Water: Check beach advisories and keep an eye on children near water.
• Insects: Use repellent and clear standing water near your home.
• Plants: Learn to recognize poison ivy and stick to marked trails.

Summer in Toronto is one of the best times of year to be outside, and a little preparation goes a long way toward making sure it stays that way. If anything comes up that feels unclear or concerning, a walk-in clinic, pharmacist, or your family doctor is always a good place to start.
