Become an Exterminator

To become a certified Exterminator, you must:

  1. Complete the application form and return it with payment of $195.00 to: Ontario Pesticide Training and Certification, University of Guelph Ridgetown Campus.
  2. Review the study materials that will be sent to you.  You will receive a Core Manual which contains information relevant to all exterminators and a Licence Category Specific Module which contains information relevant to each new licence class.
  3. Write the certification examination at a convenient date and location in your area.  The certification exam is multiple choice and is made up of two parts.  Each part consists of 50 questions.  The Core Manual exam is one-hour, closed book; the Licence Category Specific Module exam is one and a half hours, open book.
  4. Successfully complete the exam with a pass mark of 75% or greater on both parts of the exam.  You will then receive a letter of certification; you must send a copy of this letter to the MInistry of the Environment, Conservation and Parks (MECP) when you apply for a Pesticide Exterminator Licence.

If you fail on your first attempt, you have one year to rewrite the exam.  You are allowed a maximum of two more attempts during the 12 months, with no more than two attempts in any six month period.  The exam rewrite fee for failures is $75.00.

You must apply to the MInistry of the Environment, Conservation and Parks for your Pesticide Exterminator Licence within one year of obtaining certification.  The licence fee is $90 for five years.
