Killex Herbicide Canada — Bulk Pricing, Ontario 63/09 &

By Amani Khehra — Procurement Lead, ChickenPieces (Calgary, AB). Updated May 11, 2026.

If you manage a golf course in Oakville, a sod farm in Aldergrove, or a municipal grounds crew anywhere between St. John's and Victoria, you already know the name. Killex is the broadleaf herbicide Canadian turf managers have leaned on for forty years. What's changed is where you can legally buy it, what it costs in 2026, and how Ontario Reg. 63/09 affects the paperwork on your desk.

This guide answers the three questions our procurement line gets every week: where to buy Killex in Canada at bulk pricing, which provinces still allow professional and agricultural use, and how fast we can put it on your loading dock.

No fluff. We're a Calgary-based distributor, Health Canada PCP Registration #16945 is on the label, and we ship to every province.

Why Killex still wins for Canadian turf

Killex is a three-way liquid formulation: 2,4-D, mecoprop-P, and dicamba. That cocktail kills more than 50 broadleaf species — dandelion, plantain, clover, chickweed, thistle, knotweed — without harming established Kentucky bluegrass, fescue or perennial ryegrass. It is the most-registered selective broadleaf herbicide in Canadian history, and the reason superintendents and sod farmers keep specifying it is simple: it works on cool-season turf in our climate, and the dose response is predictable from Halifax to Kelowna.

Health Canada's Pest Management Regulatory Agency (PMRA) carries it under PCP Registration #16945. That number is your insurance — it means the product on the pallet is the same chemistry registered for use here, not a grey-market relabel.

Who can buy Killex in Canada in 2026?

Canada regulates pesticides at two levels: federal (Health Canada PMRA) sets the registration, and each province decides who's allowed to apply what.

Alberta, Saskatchewan, Manitoba

Professional and agricultural class use is fully permitted. Domestic class also available. No provincial cosmetic ban. Most of our bulk Killex volume ships into the Prairies for golf, sod, and municipal contracts.

British Columbia

Professional and agricultural use permitted. Some municipalities (Vancouver, Whistler) layer additional restrictions on domestic application — but commercial turf operators are unaffected.

Ontario — the one that confuses everyone

Ontario's Cosmetic Pesticides Ban Act (2008) and Ontario Regulation 63/09 prohibit cosmetic (domestic) use of Killex on lawns and gardens. But excepted uses remain legal:

  • Golf courses (with IPM accreditation under O. Reg. 63/09 Schedule 1)
  • Agricultural operations (farms, sod farms, nurseries)
  • Forestry
  • Public health & safety (poison ivy, giant hogweed control by municipalities)
  • Specialty turf (bowling greens, lawn bowling)

If you're a licensed Ontario operator in any of those categories, Killex is legal to buy and apply. You'll need a valid MECP exterminator licence under the Pesticides Act, and your applicator(s) need to be certified in the appropriate class. We don't sell to domestic Ontario buyers — that protects you and us.

Quebec

Quebec's Pesticides Management Code is the strictest in the country for domestic use. Commercial use is permitted under Permis de vente / Permis d'application from the MELCCFP. Killex is a Class 3 product — agricultural and golf course buyers ship freely.

Atlantic Canada (NB, NS, PE, NL)

Nova Scotia and New Brunswick have cosmetic bans similar to Ontario's. PEI and NL allow broader commercial use. All four provinces permit agricultural and golf course application.

Frequently asked questions

The following operator questions are answered with cited sources. Every FAQ links to Health Canada, CFIA, Canada.ca, or another authoritative regulator.

What weeds does Killex actually kill — and which ones survive it?
Killex is a selective post-emergent broadleaf herbicide that controls 50+ weed species including dandelion, ground ivy (creeping Charlie), plantain, clover, ragweed, chickweed, black medic, and Canada thistle. It contains 2,4-D, MCPP, and dicamba — the classic three-way cocktail that penetrates leaf tissue and translocates to roots. It will NOT kill grassy weeds (crabgrass, quackgrass, nutsedge) and won't harm established turf when used at label rates. For a full list, check the product label on Health Canada's Pesticide Label Search (PCP #16945).

Is Killex banned in Ontario? What does Regulation 63/09 mean for me?
Killex is NOT banned in Ontario — it is still sold at Canadian Tire, Home Hardware, and online retailers across the province. However, Ontario Regulation 63/09 (the Cosmetic Pesticides Ban) restricts the cosmetic/lawn use of Class 9 pesticides like 2,4-D on residential lawns, parks, and schoolyards. Exemptions exist for golf courses, forestry, agriculture, public works, and health/safety purposes (e.g., poison ivy control). Many Reddit users in r/lawncare and r/lawncare_canada report buying Killex in Ontario and using it on exempt properties or commercial grounds. Read the full regulation at Ontario.ca - O. Reg. 63/09.

Where can I buy Killex in the GTA / Ontario — and who ships it in bulk?
Killex is widely available across Ontario. Retail stores: Canadian Tire (~$28-35 for 1L concentrate), Home Hardware, RONA, and The Home Depot all carry it. Online: Amazon.ca, LawnSupply.ca, and ChickenPieces.com (which sells commercial-grade bulk packs and ships Canada-wide). For bulk buying (12-packs of 1L, 4L RTU, wholesale quantities), specialty suppliers like 1StopLawns.ca and Lawnstock.ca offer volume pricing. Multiple Reddit threads on r/mississauga and r/askTO confirm Canadian Tire Hamilton and Amazon as reliable sources. See Canadian Tire - Killex 1L for in-store pricing.

What PPE and safety gear do I need when spraying Killex?
According to the Killex label registered with Health Canada's Pest Management Regulatory Agency (PMRA), you must wear: a long-sleeved shirt, long pants, chemical-resistant gloves (nitrile or rubber), socks, and shoes when mixing or applying. For concentrate mixing, also wear coveralls over clothing. Do not enter treated areas until spray has dried. Wash PPE separately from household laundry. Reddit users on r/lawncare and r/Edmonton also recommend eye protection and a respirator if spraying above shoulder height or in windy conditions. Follow all label directions — the label is the law under the Pest Control Products Act (P-9.01).

When is the best time of year to apply Killex in Canada?
Apply Killex in late spring (May-June) or early fall (September-October) when broadleaf weeds are actively growing and daytime temps are between 10-25°C. Avoid application during hot, dry spells or when rain is forecast within 24 hours — the herbicide needs 6-8 hours of dry weather to absorb into leaf tissue. Spring applications catch young, vulnerable weeds; fall applications target perennials like dandelion and creeping Charlie as they store energy in their roots for winter, making herbicide uptake more effective. The official KILLEX® Liquid Turf Herbicide label confirms: "Maximum kill of weeds will be obtained from spring or early fall application."

Killex concentrate vs ready-to-use — which is more economical for a rental property?
For property managers and Airbnb hosts managing multiple units, the 1L concentrate is far more cost-effective. One 1L bottle of Killex concentrate (~$28-35 at Canadian Tire) mixes at 6 mL per 1 L of water to treat ~800 sq m (8,000 sq ft). That's roughly 167 L of ready-to-use spray from a single bottle. The ready-to-use 709 mL spray bottle (~$12-18) treats only ~140 sq m. So concentrate is about 5-6x cheaper per square foot. Multi-pack bulk buys (12 x 1L on 1StopLawns.ca or ChickenPieces.com) bring the unit cost down further. The Home Depot product page confirms 1L concentrate covers 8,000 sq ft.

How long after spraying Killex can pets and kids go back on the lawn?
The Killex label states: "Do not allow people (other than applicator) or pets on treatment area during application. People and pets may enter treated area after spray has thoroughly dried." Drying time is typically 2-4 hours in good conditions (sunny, moderate humidity, light breeze). For extra safety, many homeowners wait 24 hours or until after the next rainfall. On BabyCenter.ca forums, Canadian parents using Killex reported keeping kids off for 2-3 days when possible. For Airbnb hosts, posting a 24-hour re-entry notice protects both guests and liability. Always consult the official label at Health Canada's PMRA Label Search for the most current re-entry instructions.

Can I use a Scotts Dial 'N Spray with Killex concentrate — and what setting do I use?
Yes — Killex concentrate works with the Scotts Dial 'N Spray hose-end sprayer, a common question on Canadian lawn forums. The recommended setting is Dial position "2" or "3" depending on your water pressure and target coverage. For a standard 1L batch: fill the Dial 'N Spray reservoir with Killex concentrate to the 225 mL line (for 1,000 sq ft) or 450 mL line (for 2,000 sq ft) and top up with water to the fill line. The Lawn Supply Canada blog provides step-by-step instructions specific to Canadian Dial 'N Spray models. Always test-spray a small area first to verify even coverage, and flush the sprayer with clean water after every use.

Does Killex kill clover in lawns without damaging the grass?
Yes — Killex is very effective against white clover (Trifolium repens) and other clover species, and it will not harm established turfgrass when used at label rates. As a selective post-emergent with 2,4-D, MCPP, and dicamba, it targets broadleaf weeds while leaving grass untouched. Clover is especially susceptible because dicamba in the mix drives deep into the root system (stolons and rhizomes). Reddit users on r/lawncare and r/lawncare_canada consistently recommend Killex for clover, noting visible wilting within 3-7 days and full kill in 2-3 weeks. For heavy clover infestations on Airbnb properties, a follow-up application after 4 weeks is recommended. See the Amazon.ca product page for full weed list.

Is Killex the same as PAR III or Weed B Gon? Can I substitute them?
Killex, PAR III, and Weed B Gon MAX all share the same active ingredients — 2,4-D, MCPP (mecoprop), and dicamba — just in slightly different ratios. Killex (Ortho brand, distributed by Scotts/Green Cross in Canada) is formulated for consumer lawn use with a balanced ratio. PAR III is a higher-concentration commercial-grade formulation, while Weed B Gon MAX is the US equivalent of Killex. On RedFlagDeals and r/lawncare_canada, users note that you can substitute PAR III at roughly half the dilution rate of Killex. For Airbnb and rental property applications, stick with Killex for consistent, label-approved results. Always verify with Health Canada's PMRA Label Search — Canadian product labels can differ from US counterparts.
