Don't touch! Four toxic plants you can find (and should avoid) in Canada
Cheryl Santa Maria
Yes - it's important to get outside and enjoy nature responsibly, but the great outdoors can be a scary place!
No need to worry - today, we're talking aout toxic plants you can find in Canada, and what to do if you encounter one
It may look innocent, but there's a reason The Nature Conservancy of Canada calls giant hogweed one of the country's most dangerous plants.
When combined with sunlight, sap from the plants can cause extreme skin irritation, temporary or permanent blindness and scarring.
Burns acquired from the plant can continue to cause painful blisters when exposed to sunlight, lasting for up to a decade.
Giant hogweed was introduced to Canada via Asia, and it has thrived in our various climates.
If you come into contact with the plant, wash the area thoroughly with soap and water and avoid sunlight for 48 hours.
If you think you have been burned by giant hogweed, see a physician immediately.
Giant hogweed sightings can be reported to the Ministry of Natural Resources.
Poison Ivy is in every province in Canada, except for Newfoundland.
Touching it can result in rashes and blisters - so heed the warning: “Leaves of three - let it be.”
We know: That can be confusing, given there are a lot of plants with three leaves. Take a closer look: The stem of the middle leaf on a poison ivy plant is longer than the other two, and on each leaf, one side is bigger or wider than the other:

If you brush up against poison ivy, oatmeal baths, cold compresses and special creams will ease discomfort.
Poison sumac is found in southern Ontario and Quebe, and it’s identified by clusters of 7-13 smooth leaflets that are yellow in spring and green in summer.
Like poison ivy, it contains an oil called urushiol that causes blisters and rashes.
It may have yellow-greenish flowers and whitish-green fruits that hang in loose clusters.
Posion sumac isn't the same plant as staghorn sumac, which is found in eastern Canada, identifiable by its red, "horn-like" fruit, and is by and large not toxic.

Buckthorn can be found from Saskatchewan to Nova Scotia, likely introduced in the 1880s from Europe. It is a dangerous invasive plant. Eating its berries can result in severe abdominal discomfort in humans and animals.
Buckthron can outcompete natural plant species, leaving animals little choice but to eat the plants nutritionally-sparse berries.
When buckthorn is small - up to about three cm in height - and the soil is moist, it can easily be pulled out of the ground. You’ll need garden tools to remove larger plants. Just be sure to take all of the roots with you, or it can resprout.
