A List of Safe Non-Toxic Food Storage Containers in Canada
I’ll be the first to admit that years ago, I was happy to grab those multicolored cheap, plastic food storage containers that were constantly on sale. They seemed super convenient and extremely affordable. I had no idea that many of these containers could leach Hormone-Like Chemicals into my food.
We’ve all grown up with plastic containers as a kitchen staple, so it’s no shame if this is news to you. The important thing is that you’re here, learning about it now, and that’s what matters.
So, what’s the deal with these toxic chemicals? One of the big issues is the presence of Bisphenol A or BPA. Yes, that’s the same chemical used in the manifacturing process of cutting boards, bakeware, and in many more home essentials. You can read one of the many comprehensive reviews on the carcinogenic potential of BPA and how it can mimic estrogen, messing with your hormones and leading to reproductive issues, heart disease, and even an increased risk of cancer.
Granted, there are plenty of BPA-free food storage containers in Canada but I didn’t include them in this list because science shows that some BPA-Free plastic is made of BPA substitutes that are just as harmful as BPA. Care.com points out that 70% of all BPA-free products still leach harmful chemicals into food and beverages.
So, you won’t find any non-toxic food storage containers entirely made of plastic in my list. Instead, I focused on safe materials like glass, stainless steel, and silicone. Fair warning: most brands do use BPA-free lids, so it would be best to remove them before placing the containers in the microwave since heat can cause BPA to leach out.

The Common Toxic Chemicals in Food Storage Containers
Bisphenol A (BPA)
Bisphenol A, or BPA, is one of the most common toxic chemicals in every Canadian household as it contains strong plastics and resins. Despite its many uses, this chemical is highly toxic to our health because it can mimic estrogen, a hormone crucial for many body functions. According to a study published in Environmental Health Perspectives, this mimicry can disrupt your hormonal balance, leading to issues like reproductive problems and developmental troubles in kids.
And it doesn’t stop there. Research from the Journal of the National Cancer Institute suggests that long-term exposure to BPA could increase the risk of breast and prostate cancers. It’s a bit scary to think about, but being aware of it is the first step toward making healthier choices with non-toxic and, why not, zero-waste kitchen swaps.
Phthalates
Ever noticed how some plastics are super flexible and durable? That’s often thanks to phthalates. These chemicals are added to make plastics bendy and are found in items like plastic wraps and storage containers. But while they make our plastic products more convenient, they come with a downside.
Phthalates can disrupt our endocrine system, which regulates hormones in the body. A study published in ‘Pediatrics’ explains that children exposed to high levels of phthalates in the womb may experience developmental and behavioral issues as they grow. Another research study found that phthalates might interfere with hormone production, leading to problems like reduced fertility and metabolic disorders.
Lead
Lead is a heavy metal that used to be common in many products, including some ceramic glazes and older glass containers. Although regulations have significantly reduced its use, it can still be a hidden danger. While it can cause an array of health issues in adults, lead exposure is particularly harmful to children. The New England Journal of Medicine reported that even low levels of lead can cause significant neurological damage, affecting cognitive function and behavior. Adults aren’t safe either; the Environmental Health Perspectives has linked lead exposure to hypertension and cardiovascular diseases. It’s shocking to think that something as seemingly innocent as an old ceramic dish or glass food storage container could pose such risks.
PVC (Polyvinyl Chloride)
One of the main reasons why I solely choose plastic-free storage containers for food is the potential presence of Polyvinyl Chloride or PVC. This is another popular type of plastic that’s pretty common in food packaging, cling wraps and containers. To make it flexible, manufacturers often add chemicals like phthalates.
The Journal of Toxicology and Environmental Health explains that these additives can leach into food, posing similar risks to those we’ve discussed with phthalates, including endocrine disruption and reproductive issues. Moreover, the production and disposal of PVC release dioxins, which are highly toxic.
According to the World Health Organization, dioxins can cause reproductive and developmental problems, damage the immune system, and interfere with hormones. So, next time you’re about to wrap up some leftovers, it might be worth thinking twice about using PVC-based cling film.
Melamine
If all the aforementioned chemicals weren’t enough to persuade you to switch to the safest food storage containers in Canada, this might help you change your mind. Melamine is a chemical used in making certain plastics, including food containers, dinnerware, and utensils. While melamine itself isn’t highly toxic, it can become problematic when it leaches into food, especially if you’re heating those containers.
I recently came across a study in the Journal of the American Society of Nephrology that explains how melamine exposure is linked to kidney stones and renal failure, particularly when melamine-containing products are used to heat food. Another research in Toxicology Letters helped me to better understand how long-term exposure to low levels of melamine could lead to chronic toxicity, affecting kidney function and overall health.
So, to keep you and your family safe, I’d highly suggest opting for healthy food storage containers made of environmentally friendly, BPA-free materials.
What is the Safest Material for Food Storage?
To find the most non-toxic food storage containers in Canada, you first need to have a clear idea of the safest food contact surfaces.
Glass
Non-toxic glass food storage containers are a fantastic option for every kitchen. Because borosilicate glass is made from natural materials like sand, it doesn’t contain any harmful chemicals that could leach into your food. One of the great things about glass is its transparency—you can easily see what’s inside without having to open the lid. Besides, glass is incredibly versatile. You can pop it in the microwave or oven for reheating, and it’s dishwasher-safe for easy cleaning. If you deeply care about the environment, you’ll be glad to know that this material is 100% recyclable as well!
Stainless Steel
Stainless steel containers are another excellent choice for non-toxic food storage. They’re robust, durable, and free from harmful chemicals like BPA and phthalates. I’m talking from experience – these containers can withstand a lot—they don’t dent easily, and they’re resistant to scratches. Plus, they don’t stain or retain odours, which is a big bonus. Lastly, just like glass, stainless steel is recyclable and has a long lifespan.
Silicone
If you are looking for travel-friendly and easy-to-store non-toxic food storage containers for the freezer and microwave, silicone should be at the top of your list. I have listed a few great alternatives to zip lock bags in this guide as well as some pure silicone containers for you to choose from. Because they are made from sand, oxygen, carbon, and hydrogen, they are completely free from harmful chemicals like BPA and phthalates. One of the best things about silicone containers is their flexibility. You can easily squeeze it into tight spaces in your fridge or bag without worrying about it breaking.
BPA-Free Plastics
If you prefer the convenience of plastic containers, make sure they’re labeled BPA-free. I try to stay away from all types of plastic options but to each their own. These containers are designed to be safer by eliminating the harmful chemical Bisphenol A. They also come in a variety of shapes and sizes, so you can find the perfect container for any type of food. Plus, they’re often more affordable than other options like glass or stainless steel.

Non-toxic, BPA-Free Food Storage Containers FAQ
Are All BPA-Free Plastics Safe?
No, while BPA (Bisphenol A) is notorious for its harmful effects—mimicking estrogen and potentially leading to hormonal imbalances, reproductive issues, and increased cancer risk—its replacements aren’t necessarily better. Many BPA substitutes, like BPS (Bisphenol S) and BPF (Bisphenol F), exhibit similar endocrine-disrupting properties. These chemicals can also interfere with hormone function, potentially leading to issues like obesity, diabetes, and developmental problems in children.
Can Non-Toxic Containers be Used in Microwaves and Freezers?
Yes, most non-toxic food storage containers can be used in the microwave and freezer. Make sure the glass is labeled as microwave-safe, and when freezing, leave some space at the top of the container to allow for expansion as the food freezes. To avoid thermal shock, don’t move a glass container directly from the freezer to the microwave—let it thaw a bit first. Stainless steel food storage containers are also very durable, resist staining, and don’t absorb odours, keeping your food fresh. Just make sure the lids are also freezer-safe and not too tight, as some expansion might occur. Lastly, silicone containers are incredibly flexible and versatile. They can go straight from the freezer to the microwave without any issues. Silicone withstands a wide range of temperatures, so you don’t have to worry about it breaking or degrading.
