Mr. Speaker, I am proud to rise today to discuss Motion No. 69 and look forward to reading the amendments put forward through the deputy House leader.
I truly hope my husband is listening, because this is a personal and public service announcement. After doing this research, I am thinking of my own house, which was built in the 1960s. Are there or are there not lead pipes in my own home? I will have to go home and check tonight.
The motion aims to address the growing concerns about water quality delivered via lead pipes to private residences throughout Canada.
I will start with the concerns about lead drinking water pipes and why Canadians should be concerned about them. I will discuss solutions that have been recommended and that some municipalities addressed.
According to the Canadian guidelines, the acceptable concentration of lead found in water is 0.01% milligrams per litre. What are the consequences and why should we as Canadians be concerned?
We know that lead is a toxic metal that can be harmful to human health, especially children, infants, and fetuses. This group is very vulnerable, as exposure to this metal can lead to physical and behavioural affects. It can damage the central and peripheral nervous system, and lead to learning disabilities, shorter stature, impaired hearing, and impaired formation and function of blood cells. For fetuses, consumption of lead by the mother accumulates and can be released to the fetus. It can cross the placental barrier, exposing the fetus to lead. This can cause reduced growth of the fetus and possibly premature birth. In adults, exposure to lead can cause increased blood pressure and hypertension, along with decreased kidney function and reproductive problems.
In Flint Michigan, just across the Canada-U.S. border, close to my own home, following a change in water supply, a high concentration of lead was found. Thousands of children were exposed to these toxic substances. This was a result of Flint's use of old pipes that were corroding due to the chemical changes in the source water. We Canadians can learn from this crisis.
Research has indicated that the brain can absorb lead, which results in negative effects on the frontal cortex, which in turn can have a negative impact on essential learning and memory, and attention and planning. The effects of lead can be permanent and can result in lifelong disabilities. In the U.S., lead is considered the number one health threat to children.
According to the World Health Organization, children absorb between four to five times as much lead as adults when ingested. There is no safe level of lead in blood concentration.
What is the issue?
Here in Canada, post-war, many homes were built and both municipalities and home owners used lead pipes. It is just in the past 36 years that lead pipes have stopped being used altogether. Although the federal government has no direct involvement, at the same time we must ensure that the water for Canadians is safe to drink.
Together with the provinces and territories, Health Canada has established the “Guidelines for Canadian Drinking Water Quality”, but we must remind ourselves that it is up to the jurisdictions to set their own guidelines and enforcement.
We understand that this is cost for municipalities and homeowners to replace these pipes that have corroded over time and allowed lead to leach. Measures taken in the past few decades have greatly reduced the exposure of lead in tap water. Through proper testing, the amount of lead in water can be determined. Sampling protocols have been recommended and steps to reduce population exposure have also been provided.
We understand that it can cost homeowners up to $10,000 to replace these pipes from the municipal lines to their homes, as well as their own plumbing. We must recognize that the cost that is taken on by the municipalities is only for their own public pipelines and not for the pipeline that goes from that source into a home. This is something that homeowners will have to be aware of.
Across Canada, many municipalities have already taken action. In Halifax, a lead pipe replacement program was put in place. In Edmonton, water tests have been completed. In Montreal, the city implemented a 20-year plan to address the lead toxins in its drinking water.
Health Canada's “Guidance on Controlling Corrosion in Drinking Water Distribution Systems” is a great resource for all Canadians, whether personally or in government, to refer to. The document addresses the common issues of corrosion as well as corrosion control. The document indicates that the intent is to provide responsible authorities with guidance on assessing corrosion and implementing corrosion control for distribution systems and residential settings. It notes proper protocols and steps for monitoring. It also indicates that the role of the federal government “is primarily one of science and research, including the development of guidelines for drinking water and providing scientific and technical expertise to the provincial and territorial governments.”
We know that lead can leach into potable water through pipes, solders, and fittings.
There is guidance to prioritizing residential monitoring sites, as well as a detailed explanation of conditions that favour lead leaching in drinking water distribution, including treatment plants, distribution systems, plumbing systems, and even at our own taps. This information can be found in the document at healthycanadians.gc.ca.
Truly, what can we do?
Across Canada, many municipalities have provided testing and have worked with homeowners to replace their pipes because of health risks.
When we know that there is a solution, we should be taking action, but not necessarily at the federal level. We must recognize the inconsistency among municipalities of implementing the recommendations from the 2009 report “Guidance on Controlling Corrosion in Drinking Water Distribution Systems” and we must be sure not to duplicate our efforts. This is a familiar thing done by many different governments. We seem to constantly study and study and study, and it is the same thing. We know this is an issue, and we should be doing something about it.
Meanwhile, we can also explore the impact to communities that have lead pipes but have increased pH levels, like Vancouver. Vancouver is a bit different because it has alkalinity in its water so the corrosion does not exist. Maybe taking an opportunity to look at the pH levels and see how we can tweak them to make sure there is no corrosion is another option for the government to take.
As in the report tabled during the previous government, information already exists and we must face the challenges including methods of measuring lead, monitoring programs, and prioritizing residential monitoring sites. We must recognize the financial impact to homeowners and to the taxpayers of Canada, while keeping the health of Canadians at top of mind.
I have noted the potential health risks, especially to young children, infants, and fetuses, and the unnecessary results from lead poisoning, including a variety of permanent disabilities.
As a party, we favour the elimination of lead in drinking water; however, we must respect the jurisdiction of municipal governments. The health of Canadians must be our priority, but we must understand the unique situations across Canada, from coast to coast to coast.
As a government, the Liberals should be looking at opportunities to make sure that we can change and educate and make sure that we have opportunities when it comes to testing and any other sources.
As I indicated, the federal government is in charge of scientific expertise. This is an opportunity for the government to do that as well, and I hope it will.
