Toxic Drywall In Canada?

Posted by Jim Sparrow on Saturday, July 4th, 2009 at 10:32am.

Calgary Real EstateToxic drywall is causing concern across North America, and may make some home buyers hesitant when shopping for a new home. In an article by Bob Aaron, a Toronto real estate lawyer, called Chinese Drywall Creating Crisis, the Toronto Star reported last month that defective Chinese drywall emits toxic hydrogen sulphide, sulphur dioxide and other gasses when exposed to humidity. When the drywall off gasses it creates a noxious odour, which can result in serious health conditions and illnesses, such as breathing problems, eye irritation, fatigue, dizziness, insomnia, sore throat, bloody nose and headaches.

Bob Aaron reports that hundreds of millions of sheets of the defective drywall were imported into the United States between 2001 and 2007. It was also reported an estimated 929,000 square metres arrived in Canada through Vancouver in the same period. According to reports, much of the imported product was used in the lower B.C. mainland, but there is a good chance some made it to the Prairies, and even as far east as Southern Ontario.

Industry watchers have estimated that as few as three sheets of drywall in a house can be enough to contaminate all the walls, reported The Star. In the United States, the crisis has caused the House of Representatives to introduce the Drywall Safety Act to protect citizens. In Canada, industry experts told The Star that the scope of the problem remains to be seen. CREB® will be monitoring this issue as well.

Is US Drywall Toxic?

July 8, 2009 - Since writing this blog post last week 2 families from the USA have contacted me, both claiming their new homes have toxic drywall *suspected sulphur contaminated* manufactured in and by American companies. One of the companies is Georgia-Pacific, who manufacture a product called ToughRock®. According to their website "Georgia-Pacific Gypsum supports sustainable production of gypsum wallboard by using reclaimed gypsum, recycled paper, and clean fuels". GP manufactures synthetic gypsum wallboard (drywall) using the output of the Flu Gas Desulphurization (FGD).

My husband and I are representatives of a class-action against GP. We're looking for others with toxic American drywall. We believe that many homeowners who think they have Chinese drywall, actually have American made synthetic gypsum, but they haven't cut into their walls to see what it is. Like me, Brenda and her husband built their home on their own and know where the drywall came from.

Cynthia wrote: The defective Chinese drywall debacle has been making news for months now, with homeowners plagued by sulfur fumes that smell like “rotten eggs” and cause air conditioning coils to corrode. Residents complain of sinus and respiratory ailments, eye and skin irritation, persistent runny or bloody noses, headaches, and asthma. Some situations were so severe that residents had to vacate their homes. In some cases, victims have been harassed by builders into signing unfair, one-side remediation agreements. The issues surrounding defective Chinese drywall are confusing and worrisome. Here is a good blog that has been providing emerging and valuable information on the problems:

Madison real estate wrote: As if homeowners didn't have enough to worry about! Thank you, Jim, for bringing this important issue to light. I hope that the people whose homes are affected can diagnose their defective drywall quickly before it affects their health, and that the companies who distributed these defective and dangerous products step up to the plate and take responsibility for their actions. It is unthinkable that companies can ship such dangerous products into the marketplace. More due-diligence and testing should have been carried out. This never, ever should have happened.

We rebuilt in 2005,and have weird things happen, 3 sump pumps, copper anything turning black, smoke detectors have their own minds, light switches blow up, black spots on carpets and floors, gray green dust in vacuum that is "sticky", paint peels and bubbles. We have numerous health issues, on going and prior to today, another URI. I know for sure we have "ToughRock", I hope there is something we can do about it, I can not take this health stuff anymore, and oh yeah it's great to turn on a light and have the switch litterally blow up! Any help out there? We would appreciate anything. I did file a complaint with the CPSC.

He was dizzy, and had trouble breathing. We went from doctor to doctor and could not find out what was wrong. He has suffered terribly. He was once an outstanding athlete at the time but has be forced to give it all up. One of my daugthers has developed asthma at age 16. She never had it before. I have constant nose bleeds and my youngest son is always sick. I have been trying to solve this problem for years. We do have electrical problems and corriding copper. We have a house that has high hummidity and I think it has triggered to toxins in the drywall. What is the next step in confirming my suspicions?

I heard about the Chinese drywall problem, but just became aware of the GP ToughRock drywall issue. I found the drywall in our basement furnance room has GP ToughRock drywall, but not sure about the rest of the house. I checked the copper wirings in the house and exposed copper, but see no signs of corrosion. Just wondering how long does it take to see corrosions if I have the 'bad' drywall in my house? Is there a way to tell whether or not I have the bad toughrock drywall in my house?

I'm in Southern Ontario Canada just about to finish a basement with new "drywall"
after reading most of this i think i may not want to.
How can i tell what is good? What is bad?
Just because it comes from Home Depot and I ask them if it' s safe, ofcourse their reply is gonna be yes if it wasn't they wouldnt be selling it.
But is that true what does the guy selling it know he didnt make the stuff, he isnt a scientist that does the testing, he is just the guy selling it.
What the heck can I do now the basement is getting finished for my son to have his own place.
I don't wanna make him sick or worse.
Is there a site that can tell me what drywall is good and what is bad, as in name brands and even still how can those sites be sure the drywall wasn't in a warehouse somewhere for 10 years?
Wow maybe my kid wont get his own place after all

Colleen wrote: Susan, I know of testing labs in the United States that can test the drywall for you but first there are some things you can do yourself. Take out the outlets in your house and look at the copper ground wire. This wire should be shiny copper not black. If it is black then you, more then likely, have a CDW (Chinese Drywall) problem. The one thing to know in looking at the outlets is that you have to take out ALL of the outlets. In our home not every room was built with CDW. In certain rooms the wires look like copper while in other rooms they are completely black. If you do find black on your wires then you should take the next step of getting the drywall tested by a professional firm just to have it in writing. If you have any questions please feel free to contact me at and check out our website at There are pictures on the website so you can see what the wires look like. I hope you find that you do not have CDW in your home. This has created a nightmare for my family and tens of thousands of American families all across our country.
