    It's an invasive plant that can cause second degree burns if you touch it. My friend's 3-year-old touched this plant in a yard in Brampton a few months ago .. he had huge raised blisters across the back of his hand and wrist the next day, and he still has scars today.
    I didn't know we had plants this dangerous around here! I haven't seen it personally but this is what it looks like:
    And here's some information about it:

    They are photosensitive toxins. If you get the sap on you that part of your body will have an increased sensitivity to sun for LIFE. Sucks.

    If it gets in your eyes or bloodstream it can cause permanent eye damage/blindness. So don't get it in your eyes or bloodstream.

    And whatever you do, don't use pesticides, because they are illegal and only serve to prevent noxious weeds from taking hold.

    what is is with tribe and work colliding these days? I can comment on this one though.

    yes - it's an invasive plant, it's been here for years but the population is increasing. It was most likely brought over as an ornamental, which is how most plants get here. We also have Wild Parsnip, which can do the same thing.

    Both species prefer sunny upland fields but can also be found in ditches and along the edge of wet meadows.

    Giant Hogweed:
    Massive plant with coarse, jagged leaves and a flat, umbrella shaped flowering head with numerous white flowers.
    Commonly exceeds 2 m in height.

    Wild Parsnip:
    Smaller – less than 1.5 m in height
    Flowers on its umbrella-shaped flowering heads are yellow

    What Happens:
    The sap from both species, in contact with exposed skin, can cause phytophotodermatitis (severe skin inflammation) when exposed to sunlight (even under cloudy conditions)
    Blisters form within 48 hours of exposure
    Scarring can last from months to several years.
    Even small amounts of sap in the eyes can lead to temporary or permanent blindness.

    What can you do:
    Protective clothing (including eye protection) should be worn when handling these species in any way
    If you think you’ve been in contact with hogweed or parsnip…wash the affected areas immediately with soap and water if available
    Keep affected areas out of direct sunlight (if you get sap on you cover it immediately)
    Seek medical advice as soon as possible (if phytodermatitis develops)

    If you have any on your property let me know and I'll send over some removal tips.

    Also all sightings should be reported to the invasive species hotline - 1-800-563-7711 or to OFAH Invading Species Awareness Program so that locations and spread can be better monitored.

    actually, if you knew the pesticide act you would realize that some pesticides are allowed for noxious plants for exactly that reason. It's cosmetic uses that are banned. Pesticides Act - O. Reg. 63/09

    Health or safety, poisonous plants

    22. (1) No person shall use a pesticide mentioned in section 16 to destroy, prevent or control plants that are poisonous to humans by touch, including poison ivy, poison sumac and giant hogweed, unless,

    (a) the person is a licensed exterminator authorized to perform the extermination; and

    (b) the person uses,

    (i) a Class 2, 3 or 4 herbicide whose only pesticide ingredient is a Class 10 pesticide, or

    (ii) a Class 5, 6 or 7 herbicide. O. Reg. 63/09, s. 22 (1).

    (2) Despite subsection (1), any person may use a Class 5, 6 or 7 herbicide to destroy, prevent or control a plant mentioned in subsection (1) if the person uses the herbicide on land that he or she owns or occupies. O. Reg. 63/09, s. 22 (2).

    Is this plant a cousin of the infamous 'dickweed' I heard so much about in elementary school?

    Well, one thing is for sure: I am now going to start wearing gloves whenever i pull any kind of weed out of the garden.

    Everytime I pull my Giant Hog it seems to grow right back a few hours later, and just as deadly as ever.

    Yeah but pulling the plant out of the ground may take more than 6 seconds.
