Final answer:
In Canadian regulations related to Hazardous Products, the supplier has the option to not provide information in sections 12 (Ecological Information), 13 (Disposal Considerations), and 14 (Transport Information) of the Safety Data Sheet if not relevant or required.
Step-by-step explanation:
Under Canadian regulations, specifically the Hazardous Products Regulations (HPR) which aligns with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), the supplier has the option to not provide information in sections 12, 13, and 14 of the Safety Data Sheet (SDS). These sections cover Ecological Information, Disposal Considerations, and Transport Information respectively. Suppliers may omit this information if it is not relevant or required under certain circumstances. However, the other sections of the SDS are essential and must be included to ensure proper safety measures are communicated.
