Changes to the regulation allow it to be interpreted and enforced in a way that is consistent with it's original intent. The changes clarify the use of key terms, delete references to outdated implementation dates and clarify minor details regarding the supervisory requirements of technicians and trainees.

There are several changes to the regulation that may be of interest to members of the pest management industry:

• Licensed exterminators can now act as technicians for exterminators they are not authorized to perform. An exterminator, who is the holder of a license that is appropriate for the type of extermination being conducted, can now have another licensed exterminator, who is not appropriately licensed to conduct the extermination, assist him or her but under the condition that the assisting licensed exterminator is deemed a technician.
• Licensed exterminators, technicians and trainees are no longer required to carry their documentation on their persons. This is because documentation could become contaminated by pesticide exposure and this is a health concern. They will now have the option of having the documentation readily available at the site of the extermination.
• It is now the employer's responsibility to keep on file technicians' and trainees' training records. Previously it was the responsibility of the supervising licensed exterminator.
• Containers holding pesticide solutions, such as spray tanks, must have securable openings, and be locked when left unattended.
• A provision has been added to the regulation to allow licensed exterminators who conduct formal classroom training courses for technicians and trainees, to supervise more then three technicians/trainees at the same time, as long as not compensation is received for an exterminations performed as part of the training.
• 100 per cent chloropicrin, applied as an agricultural preplant soil fumigant to control fungi and nematodes, has been added to the pesticides that can be used by the holders of fumigation-soil licenses.
• A licensed exterminator must now obtain a purchase and use permit in order to use a Schedule 1 product for a land extermination. This strengthened the permit requirements for the more highly toxic and persistent pesticide products.

• Obsolete dates have been removed from the regulation.
• The term "site of extermination" has been made consistent throughout the regulation.
• Placards posted for structural fumigations must be sufficiently illuminated, and therefore readable at all times.
• Insurance exemptions for users of pesticides that do not need and exterminator's or operator's license have been clarified.
• Wording used to describe the responsibilities of licensed exterminators performing structural fumigations, with respect to locking and sealing doors, have been clarified.
