If you manufacture, import or sell certain sealant products or certain products that contain 2‑butoxyethanol (2‑BE), Environment and Climate Change Canada wants you to be aware of new regulations that may apply to you, and to inform you of resources, including a compliance guide, that can help you understand and comply with its requirements. THE Certain Products Containing Toxic Substances Regulations The Certain Products Containing Toxic Substances Regulations (the Regulations)were published on March 12, 2025. They prohibit the manufacture, import and sale in Canada of certain products that contain toxic substances, and in some cases, specify concentration limits that must not be exceeded. The objective of these Regulations is to protect the environment and human health in Canada. As of December 31, 2025, most prohibitions and regulatory requirements under the Regulations have come into force, except where exemptions may apply. Note that some of these regulated products containing 2-BE were previously managed under the 2-Butoxyethanol Regulations, which have now been repealed and integrated into the Regulations. There are no major changes in requirements for these products. Regulated Products, applicable Limits and Coming-Into-Force Dates Currently, the Regulations target the following types of products containing toxic substances:
