Where can you buy HOCl disinfectant in Canada?

Hypochlorous acid disinfectant is sold in Canada directly by Canadian manufacturers and authorized distributors. The most reliable route is to buy from a source that publishes its Health Canada authorization and its current Canadian label, so you can confirm what you are buying before it ships. Solus manufactures its HOCl Multi-Purpose Disinfectant in Québec and sells it directly through the Solus product range, with authorization no. 02557371 and its documents available on the Solus documents page.

Buying from a Canadian source matters for more than shipping speed. A Canadian-authorized product carries a label written for Canadian use areas and Canadian regulatory wording, and a Canadian supplier can ship to you without cross-border import questions. Solus ships within Canada only, which keeps the authorization, label, and delivery aligned to the same market.

What should you check before buying HOCl in Canada?

Start with the authorization. Confirm the product holds a current Health Canada authorization — for Solus, biocide market authorization no. 02557371 — and that the use area you need (for example, Food Premises or Hospital / Health Care Facilities) is actually listed on the current label. A registration number identifies an authorized product; it is not a ranking or a blanket safety claim, so read the label for the surfaces, contact time, and rinse directions that apply.

Then check the practical details. Confirm the concentration on the current label (Solus’s is 367 ppm free available chlorine), the available formats and their fit for your volume, and whether the seller ships to your location. Review the label and Safety Data Sheet for directions and precautions, including the potable-water rinse required after application on surfaces or objects that may directly contact infants or toddlers, animals, food, feed, or drinking water. If a seller cannot show a current Canadian authorization and label, treat that as a reason to look elsewhere.

Which format should you choose?

For kitchen workflows, see How to disinfect a commercial kitchen.

The 946 mL, 3.78 L and 18.9 L formats all contain the same Multi-Purpose Disinfectant, so the choice is about volume, storage, and workflow rather than a change in the product. A 946 mL container suits point-of-use application and trial; 3.78 L and 18.9 L suit routine facility use and refilling. For high-volume or facility-scale supply, the 205 L and 1000 L industrial formats are available by contacting Solus rather than through the standard online checkout.

Is “HOCl spray” a different product?

No. “Spray” describes how the liquid is applied — through a trigger sprayer or spray application onto the hard, non-porous surface — not a separate formulation. The same 367 ppm Multi-Purpose Disinfectant is applied by the method the label supports; searching for “hypochlorous acid spray” and “hypochlorous acid” in Canada generally leads to the same category of product. Whatever the application method, keep the surface wet for the full label contact time and complete the potable-water rinse where the label requires it.

How does Canadian availability compare to buying from US sellers?

Many hypochlorous acid products visible online are US direct-to-consumer brands. For Canadian buyers, a US listing can mean cross-border shipping, customs handling, and a label written for another market’s regulatory framework. Buying a Canadian-authorized product avoids those issues: the authorization, the label wording, and the shipping all match the Canadian market. Solus ships within Canada only, so the product you receive is the same authorized product described on the site.
