The CWPA is a non-profit organization that facilitates an annual convention where the latest developments in science, technology and economics of wood preservation are presented to stakeholders and members in the wood preservation industry.


Membership of the association is open to any person with an interest in the field of wood preservation and protection. Please note that CWPA memberships are offered on an individual basis and are non-transferable.

membership benefits

CWPA has immediate access to a wide-range of technical information on all aspects of wood preservation.

CWPA publishes an annual newsletter to provide members with up-to-date information on issues facing the wood preservation industry.

CWPA hosts an annual convention (typically in the Fall) in alternating Eastern and Western Canada locations. This two-day event invites internationally acclaimed speakers to present papers on topical aspects of wood preservation – such as environmental issues, and the latest advancements in preservatives and application technology.

  • Full Membership $175/year
  • Student Membership $25/year


The Robert W. Stephens Memorial Award is available to graduate students, post doctoral or beginning scientists involved in research pertaining to wood preservation. The award supports travel and attendance costs for young scientists to present the results of their research at the annual CWPA convention.

  1. The award is merit based and designed to inform the membership of ongoing research; it also allows young scientists to present their research at the annual CWPA conference, thereby meeting others in the field as well as potential employers.
  2. The award is open to members and non-members of CWPA.
  3. The award is meant for entry level researchers including graduate students, post doctoral fellows and other researchers within the first 3 years of full-time employment.
  4. The amount of the award is $1,000.
  5. One or more awards may be given at the discretion of the Awards Committee and the Board of Directors.
  6. There is no limit to the number of applications from an individual institution.
  7. The R.W. Stephens award can only be granted once to an individual.
  8. Successful applicants must present their research at the conference and prepare a paper for the conference proceedings and participate fully throughout the whole conference (the final condition may be waived in exceptional circumstances).
  9. The cost of conference registration, including scheduled conference meals, will be waived for successful applicants.
  10. Successful applicants will also be acknowledged at the annual meeting and presented with a certificate and awarded one year’s membership to the CWPA.
  11. R.W. Stephen’s award applications must be submitted to the CWPA by June 1, preceding the annual conference.
  12. Applicants will be informed of the results of the competition, normally by June 30. Successful applicants must confirm acceptance within two weeks of being informed of the decision.
  13. Applicants must provide the following information:
  • Name, address, email address, telephone number;
  • CV including educational background, professional experience and publications;
  • Draft manuscript including scientific and technical impact of the research
