Health Canada Warns of Counterfeit Viagra and Cialis in Southern Ontario
Fake Erectile Dysfunction Drugs Found in Mississauga

The federal health regulator has issued a public alert concerning counterfeit prescription medications discovered in the Greater Toronto Area. Health Canada confirmed the presence of fake versions of the popular erectile dysfunction drugs Viagra and Cialis at a distribution facility in Mississauga, Ontario.

Details of the Counterfeit Medication Discovery

According to the official advisory published on January 12, 2026, the counterfeit products were identified at Bitco Distribution in Mississauga. The fake tablets were designed to mimic 20 mg tadalafil tablets (sold as Cialis) and 100 mg sildenafil tablets (sold as Viagra). These medications are prescription-only treatments for erectile dysfunction, and their unauthorized, counterfeit versions pose significant health risks.

Health Canada emphasized that these illicit products were not authorized for sale in the country. The agency did not specify how many fake pills were seized or whether any had been distributed to consumers or pharmacies prior to the discovery. The investigation into the source and distribution network of the counterfeit drugs is ongoing.

Risks Associated with Counterfeit Pharmaceuticals

Consuming counterfeit medications is extremely dangerous. Unlike regulated pharmaceuticals, these fake pills are manufactured in unlicensed, often unsanitary facilities with no quality control. They may contain incorrect doses of the active ingredient, no active ingredient at all, or harmful contaminants like heavy metals, pesticides, or other undisclosed drugs.

Potential health consequences include uncontrolled side effects, dangerous interactions with other medications, treatment failure, poisoning, or severe allergic reactions. For individuals with underlying heart conditions, taking unverified erectile dysfunction medication can be particularly hazardous.

How to Protect Yourself and Verify Medications

Health Canada urges consumers to exercise extreme caution. Always obtain prescription medications from a licensed pharmacist following a valid prescription from a healthcare practitioner. Be wary of purchasing drugs from unknown online pharmacies, social media platforms, or other unverified sources that offer significantly lower prices.

To verify the authenticity of a medication:

  • Check the packaging for spelling mistakes, poor print quality, or altered logos.
  • Ensure the drug has an eight-digit Drug Identification Number (DIN), Natural Product Number (NPN), or Homeopathic Medicine Number (DIN-HM) on the label.
  • Examine the pills themselves for unusual color, size, shape, or texture.

Anyone who believes they may have purchased or consumed a counterfeit product should stop using it immediately and consult a healthcare professional. Suspected counterfeit drugs can be reported to Health Canada through its Public Enquiries line or the Regional Product Safety Office.

This incident highlights the ongoing challenge of illicit drug networks operating in Canada and serves as a critical reminder for the public to prioritize safety over cost when it comes to personal health.
