3 More Victoria Beaches Flagged: Updated Dog Safety Guide for 2026
By Happy Homes Team at eXp Realty, Victoria, BC
- ▶ 3 new beaches added to the advisory list since our July 18 report: Langford Lake Leigh Road, Cadboro Gyro Park Beach, and Boss Bay Beach. This brings the total to 8 active or standing advisories across Greater Victoria.
- ▶ Langford Lake is a serious concern for dog owners. It is one of the most popular dog swimming spots in the West Shore. The advisory was issued July 30 for unsatisfactory bacteriological water results, and we are hearing from local dog owners who swim there regularly.
- ▶ Gonzales Bay was re-tested and re-flagged on July 27, 2026, confirming the bacteria problem there is ongoing. Cadboro Gyro Park Beach was flagged the same day.
- ▶ Blue-green algae advisories remain active at Thetis Lake, Prior Lake, and Beaver Lake. These toxins can cause lethal liver damage in dogs and can be present even without visible algae.
- ▶ Bottom line for dog owners: Keep dogs on leash at ANY beach with an advisory. Check Island Health's beach advisory page before heading out.
As of July 30, 2026, eight beaches in Greater Victoria carry active Island Health advisories after three more locations were added to the list. According to Victoria Buzz and Island Health's beach advisory page, the new advisories cover Langford Lake Leigh Road (issued July 30), Cadboro Gyro Park Beach (issued July 27), and the long-standing Boss Bay Beach advisory (in effect since June 2024). This is a follow-up to our July 18 report on 7 Victoria beaches declared unsafe for swimming, and we want every dog owner in Greater Victoria to understand what has changed and why it matters for your pup.
We are the Happy Homes Team, and we write the Victoria Dog Guide with our two Chief Canines: Ziggy (our 6-year-old Rottweiler) and Sahara (our 13-year-old Lab mix). When a new beach gets flagged, especially one as popular with dogs as Langford Lake, we pay attention. Here is the full updated picture, what the new advisories mean for your dog, and what to do next.
The Updated List: 8 Beaches with Active Advisories
Here is the complete, updated list as of July 30, 2026. New beaches are marked with a warning icon. Beaches carried over from our previous report are included so you have everything in one place.
Langford Lake (Leigh Road) : Unsatisfactory Bacteriological Water Results
Advisory issued July 30, 2026. Langford Lake is one of the most popular freshwater swimming and recreation spots in the West Shore, and it is a favourite for dog owners. The Leigh Road access point has been flagged for unsatisfactory bacteriological water quality results. This is a significant development for the Langford and Colwood community.
Dog risk: High. This is a popular dog swimming lake. Dogs who swim in or drink from Langford Lake are at risk of exposure to the contaminants behind the advisory. Keep your dog out of the water at Langford Lake until the advisory is lifted. We are particularly concerned about this one because we know so many local dogs cool off here in the summer.
Cadboro Gyro Park Beach : Unsatisfactory Bacteriological Water Results
Advisory issued July 27, 2026. Cadboro Bay, commonly called Gyro Beach, sits within the Victoria Harbour Migratory Bird Sanctuary and is on-leash year-round for dogs. The beach is a popular family destination near the University of Victoria campus, and the advisory covers the swimming area off Gyro Park.
Dog risk: Moderate. Cadboro Bay is on-leash already due to the bird sanctuary, so dogs are less likely to be swimming freely here. However, a leashed dog can still drink contaminated water or wade in the shallows. Keep your dog away from the water line entirely. Rinse paws and coat if your dog does enter the water.
Boss Bay Beach : Unsatisfactory Bacteriological Water Results
Long-standing advisory in effect since June 18, 2024. Boss Bay is a smaller, quieter beach along the Gorge Waterway. Island Health's advisory has been continuously in effect for over two years, reflecting persistent water quality concerns at this location.
Dog risk: Moderate to high. The long-standing nature of this advisory suggests ongoing contamination issues. Dogs should not swim in or drink from the water at Boss Bay. The beach and surrounding park are fine for a leashed walk, but keep your dog away from the shoreline.
Gonzales Bay Beach : Elevated Bacteria (Re-Flagged)
Gonzales Bay was re-tested and re-flagged on July 27, 2026 for elevated bacteria levels. This confirms the contamination at Gonzales is not a one-time event. As we reported in our July 18 article, Gonzales Bay tested high for enterococci bacteria. Dog owners should note that Gonzales Beach also has seasonal dog restrictions: dogs are completely prohibited June 1 through August 31 due to the migratory bird sanctuary.
Dog risk: Moderate to high. Enterococci bacteria can cause gastrointestinal illness in dogs who drink the water. Since dogs are already prohibited in summer, the advisory primarily affects off-season visitors.
Thetis Lake Beach : Blue-Green Algae (Still Active)
Advisory issued June 23, 2026 and still in effect. Thetis Lake remains one of the most popular swimming and walking spots in View Royal, and the blue-green algae advisory continues through the summer season. See our original beach advisory report and our 2026 blue-green algae guide for full details.
Dog risk: High. Cyanobacteria toxins can be fatal to dogs. Keep dogs out of the water entirely.
Prior Lake : Blue-Green Algae (Still Active)
Advisory issued July 14, 2026. Prior Lake remains under a blue-green algae advisory. This smaller lake on the Saanich Peninsula is less busy than Thetis, but the cyanotoxin risk is the same.
Dog risk: High. Same cyanotoxin concerns as Thetis Lake.
Beaver Lake : Blue-Green Algae (Long-Standing Advisory)
Advisory in effect since October 2023. Beaver Lake, located in the Elk/Beaver Lake Regional Park in Saanich, has a long-standing blue-green algae advisory that is renewed each season. The cyanobacteria bloom returns annually.
Dog risk: High. Dogs must be kept away from the water entirely.
Art Mann Park : Unsatisfactory Bacteriological Water Results
Long-standing advisory in effect since January 2015. Art Mann Park's advisory along the Gorge Waterway in Saanich has been continuously in effect for over a decade. This is a permanent feature of the local beach landscape.
Dog risk: Moderate to high. Dogs should not swim in or drink from the water. Use the park for walking trails only.
Langford Lake is a major dog swimming spot. This advisory is personal for many of us.
Langford Lake is the go-to freshwater swimming spot for dog owners across the West Shore. On any summer weekend, you will find dozens of dogs fetching sticks, paddling in the shallows, and drinking from the lake while their owners relax on the grassy banks of Leigh Road. With the July 30 advisory for unsatisfactory bacteriological water results, that routine needs to change immediately.
Unlike ocean beaches where salt water provides some natural filtration, freshwater lakes like Langford Lake concentrate bacteria and algae. When a lake is flagged for unsatisfactory bacteriological results, it means the bacterial count is high enough that swimming poses a health risk. For dogs, who drink the water directly while swimming, the risk is significantly higher than for humans.
What to do if you regularly swim with your dog at Langford Lake:
- ▶Stop going into the water. Full stop. Until Island Health lifts the advisory.
- ▶Keep your dog on a leash at Leigh Road park and steer clear of the shoreline.
- ▶Bring fresh water and a bowl so your dog is not tempted to drink from the lake.
- ▶Share this information with other dog owners in Langford and Colwood. Many people check the CRD's beach monitoring page, but not everyone knows to check Island Health directly.
Blue-Green Algae: The Danger Has Not Passed
It is important to remember that the blue-green algae advisories at Thetis Lake, Prior Lake, and Beaver Lake remain active. These are not seasonal announcements that disappear with a single cool day. Blue-green algae (cyanobacteria) produce toxins that cause acute liver damage in dogs, which can be lethal, and they can be present even when no visible algae is visible on the water's surface.
We covered blue-green algae extensively in our 2026 blue-green algae guide and in our initial beach advisory report. The key message remains: if you see a blue-green algae warning sign at any lake, keep your dog out of the water, on leash, and away from the shoreline. Even a few laps of contaminated water can deliver a dangerous dose of cyanotoxins.
Read this before you head to any beach or lake with your dog:
Blue-green algae: invisible danger, lethal for dogs.
Blue-green algae (cyanobacteria) toxins can cause LIVER DAMAGE in dogs if ingested. This can be lethal. Critical warning: cyanobacteria can produce toxins even when there are no visible signs of algae in the water. Just because the water looks clear does not mean it is safe. Dogs are especially vulnerable because they drink the water directly while swimming.
Bacteriological contamination: more than just a stomach ache.
When a beach is flagged for unsatisfactory bacteriological water results, it means bacteria levels exceed health thresholds. Dogs who drink the water or swim in it can develop serious gastrointestinal illness. Dogs also lick their fur after swimming, which means secondary ingestion is almost guaranteed.
Know the symptoms of waterborne illness in dogs.
- ▶Vomiting or diarrhea (often the first sign)
- ▶Excessive drooling or foaming at the mouth
- ▶Lethargy, weakness, or stumbling
- ▶Loss of appetite or refusal to drink
- ▶Muscle tremors or seizures (especially with cyanotoxin exposure)
- ▶Yellowing of gums or eyes (indicating liver damage from algae toxins)
What to do at any beach with an advisory:
- ▶Keep your dog on a leash. A fixed-length leash gives you control to steer your dog away from the water.
- ▶Look for warning signs. Island Health posts warning signs at all impacted locations. If you see a sign, the advisory is active.
- ▶Bring your own fresh water and a bowl. This is the simplest way to prevent your dog from drinking lake or ocean water.
- ▶Rinse your dog thoroughly after any beach visit, even if the water appeared clean.
Bottom line: even if you cannot see contamination, bacteria and toxins can still be there. Advisories exist for a reason. Respect every posted warning and keep your dog on leash at any beach with an active advisory.
How to Check Beach Water Quality Before You Go
With the advisory list growing to 8 beaches, checking water quality before every trip is more important than ever. Here are the resources we use:
- Island Health Beach Advisory Page: The official source for all current beach advisories in the Island Health region. This is the most up-to-date resource and the one we check first.
- CRD Beach Water Quality Monitoring: The Capital Regional District's official monitoring page. Updated during the summer sampling season (mid-May through Labour Day).
- CRD Algae Monitoring Page: Specific to blue-green algae blooms at freshwater lakes.
- Victoria Buzz: Local news outlet that regularly reports water quality advisories as they are announced.
We recommend checking these sources the morning of any planned beach day. Advisories can be issued or lifted quickly, and conditions change with rainfall and temperature.
Which Greater Victoria Beaches Are Currently Safe for Dogs?
The good news: many of the best dog-friendly beaches in Greater Victoria remain safe and open. Ocean beaches are not affected by the freshwater algae blooms, and most saltwater locations have no active advisories. Here are safe options to enjoy right now:
- Parker Park (Cordova Bay): Year-round off-leash beach in Saanich. Ocean saltwater, no algae concerns, no water quality advisory. Ziggy's favourite spot.
- Dallas Road Waterfront: Victoria's iconic oceanfront dog walk. Off-leash strip above the beach, on-leash on the beach itself. Saltwater, no current advisory.

Symptoms to Watch for If Your Dog Swam at an Affected Beach
If your dog swam at any of the eight flagged beaches recently, watch for these symptoms over the following 24 hours. This is especially important for Langford Lake, which was only flagged on July 30 and many dog owners may not yet know about the advisory.
- ▶Vomiting or diarrhea (often the first sign, sometimes with blood)
- ▶Excessive drooling or foaming at the mouth
- ▶Lethargy or weakness, reluctance to move, stumbling
- ▶Loss of appetite or refusal to drink water
- ▶Muscle tremors or seizures (especially with cyanotoxin exposure)
- ▶Difficulty breathing
- ▶Yellowing of gums or eyes (indicating liver damage from algae toxins)
If your dog shows any of these symptoms after swimming: Contact your vet immediately. Mention that your dog was in a beach with known water quality issues. Time is critical, there is no specific antidote for cyanotoxins, and supportive treatment must begin as early as possible.
Two 24/7 emergency veterinary options in Greater Victoria are WAVES (West Coast Animal Veterinary Emergency Specialty Hospital) and Central Victoria Veterinary Hospital (VCA). Save their numbers in your phone before heading to any beach.
