Hon. David M. Wells: Honourable senators, I rise this evening to speak to Bill C-224, An Act to establish a national framework for the prevention and treatment of cancers linked to firefighting.

For thousands of men and women in firefighting, the job is more than a profession. Firefighters face risks every day to protect others. They put themselves on the line for their communities, for citizens and for each other. It is well known that firefighters encounter carcinogens and toxins on a daily basis.

Initially, exposure was believed to occur from breathing in chemicals released during fires, as well as smoke, soot and asbestos. Further research has confirmed that those toxins can also be ingested and absorbed through the skin. The World Health Organization’s International Agency for Research on Cancer, in July 2022, declared firefighting as a Group 1 carcinogen, the classification with the highest cancer hazards.

Through years of toxic exposure, firefighters contract cancer up to nearly four times the rate of the general population. Overall, the average Canadian has a 44% risk of developing cancer in their lifetime. This grows to 53% for firefighters. While a person has a 30% risk of dying of cancer, the mortality rate in firefighters is 44%.

To put these numbers into greater perspective, last year, 95% of deaths among Canadian firefighters were attributable to cancer. As a result, firefighting practices have increasingly emphasized the proper personal protective equipment usage, decontamination protocols and other measures like scrub-down areas in fire stations to minimize exposure to carcinogens.

However, in spite of these efforts, a growing body of research has shown that firefighters have been further exposed to deadly chemicals through the very gear that is supposed to protect them.

Firefighting coats and pants, as part of the collective gear, contain high concentrations of per- and polyfluoroalkyl substances, referred to as PFAS. PFAS are a class of more than 12,000 synthetic chemicals primarily used as surface treatment for the purpose of repelling water and oil. Their strong, long-lasting carbon-fluorine bonds make it so that many of them do not degrade in the environment and are difficult for the body to secrete. For this reason, they are known as “forever chemicals.”

PFAS are not exclusive to heavy-duty equipment and gear. In fact, these chemicals are found in everyday household items like cleaning products, rain jackets, umbrellas, tents, non-stick cookware and in the stain-resistant coatings used on carpets, upholstery and other fabrics like gym gear. They are even in personal care products like shampoo, dental floss, nail polish and makeup.

I deliberately note this, colleagues, to paint a picture of how integrated PFAS are in our lives. Through a number of toxicological studies, PFAS have been shown to impact behavioural development and metabolism as well as the circulatory, immune and endocrine systems. The U.S. Centers for Disease Control and Prevention outlines a host of health effects associated with PFAS exposure beyond cancer, including liver damage, decreased fertility and increased risk of asthma and thyroid disease.

Now imagine wearing 45 pounds of work clothing covered in it every day.

It is also important to acknowledge that the high levels of heat firefighters face while battling fires help in releasing these toxins from the gear so that they regularly seep into the skin, are breathed in or enter the body through inevitable tactile transmission.

Emerging research has forced firefighters to reconcile that flames are not what they need to be most concerned about. It is the risk of cancer. In that regard, we must reassess the globally standardized gear that firefighters are required to wear. Colleagues, as you will recall, this bill would create a national framework to raise public awareness of cancers related to firefighting with the goal of improving firefighters’ access to cancer prevention and treatment. As critic of this bill, I wonder: How can the development of a framework be a solution?

Certainly, conversations on the merits of awareness should be had. However, true, effective change needs curative measures and not palliative solutions. If the goal is to reduce cancer for firefighters, we need to look at its sources and adjust accordingly. While little can be done to prevent the chemicals released during a fire, there is a direct, obvious solution in what is being worn in the first place, and it is simply to replace it with something safe.

Currently, firefighting protective gear contains PFAS to repel water and oil. Yet, as mentioned earlier, well-established science shows that its benefits are greatly outweighed by the dangers. Fortunately, safer substitutions exist with many more projects underway in an effort to transition away from these forever chemicals.

According to a Danish research report entitled Durable Water and Soil repellent chemistry in the textile industry, there are a number of alternative products on the market that provide durable water and oil repellency. These products contain modifications to their general chemistries that consequentially adjust their carcinogenic risk. There were five mentioned in detail in the report: paraffin repellent chemistries, stearic acid-melamine repellent chemistries, silicone repellent chemistries, dendrimer based repellent chemistries and nano-material based repellent chemistries. All these substitutes have chemical compositions that do not meet the definition of PFAS. In other words, they can be considered as safer alternatives to the chemical of concern when developing innovative firefighting gear.

As research is ongoing, I encourage the federal government to bring this crucial issue into consideration when developing this national framework. The concerns I have raised fall well inside the scope of this bill, given their direct link to cancer.

This is but one step the federal government can and must take to lower the risk for our firefighters and address their legitimate health and safety concerns. I would like to take a moment in my remarks to express that I’m fully supportive of this bill. In taking my role as critic seriously, I highlight the concern of firefighting gear to emphasize the necessity of this legislation and recommend a way to strengthen it within the existing purview of the bill.

The only reservation I have with this bill is that its original iteration, Bill C-224, included the line “provide for firefighters across Canada to be regularly screened for cancers linked to firefighting . . . .” I believe it was a very important element. However, this was later weakened to read, “make recommendations respecting regular screenings for cancers linked to firefighting.” Rather than requiring the government, it downgraded the measure into a recommendation. As someone who recognizes the separation of federal and provincial jurisdiction — and that is what this change was based upon — I can see why the change was made. However, I still think it does not stand as strong as it did in its original form. When it comes to protecting our firefighters from occupational diseases, time is of the essence. The earlier we screen for cancers, the better the outcomes, which is crucial given the implications and merit of this bill. Nevertheless, I’m proud to be involved in such a critically important bill.

Firefighters risk their lives every day to protect our communities, homes and lives. We must be there for them the same way they are there for us. This bill is one way of doing so by acknowledging the long-term health risks of firefighters and setting out frameworks to better protect them in the line of duty. It impacts far more than the firefighter. It impacts their entire family and the entire structure of our communities. Colleagues, this bill can save lives.

Thank you.
