Revised Version (March 2023) of the CLS is now available!
Your purchase of the CLS includes a three year subscription with regular updates.
The CLS chapters 1-6 (excluding section 5) have been completely revised and a summary of those revisions is published at the beginning of the document. Section 5 (soils) is currently being revised.
The CLS is an indispensable tool to the success of any landscape project that is designed, built and maintained to this nationally recognized standard.
Good planning, building and maintenance of gardens and spaces is critical to protecting your investment in green infrastructure from the roots up.
The Canadian Landscape Standard is a resource which defines good landscape construction practices. It should be used by land developers, parks staff, landscape architects, landscape contractors and the building industry.

About the Canadian Landscape Standard
Nastaran Moradinejad, BCSLA, AALA, CSLA, Appointed Chair of the Canadian Landscape Standard Steering Committee
It is with great pleasure that the CSLA announces Nastaran Moradinejad's appointment as Chair of the CSLA and CNLA Joint Canadian Landscape Standard (CLS) Steering Committee. Ms. Moradinejad has served on the CLS Steering Committee since 2017 and has contributed to the development and launch of the second edition.
According to Christene LeVatte, past chair of the CLS Steering Committee:
"Nastaran's contribution to the CLS has been truly exceptional. Her appointment will ensure the CLS's continued integrity and development of new content."
The Canadian Nursery Landscape Association and the Canadian Society of Landscape Architects, who jointly administer the CLS, would like to express their gratitude to Christene Levatte, who has, since 2014, participated as a member of, and then led the CLS Steering Committee through the first and second editions. Her vision for the CLS and commitment to the project were instrumental in realizing this important guideline for the landscape architecture and landscape construction industries.
The Canadian Nursery Landscape Association and the Canadian Society of Landscape Architects (CSLA) joined forces to create a new tool that sets guidelines for landscape construction projects across Canada. The Canadian Landscape Standard is intended for use by anyone who specifies, designs, builds or maintains landscape work. Using the highly successful BC Landscape Standard as a basis for the Canadian version, the standard is a national document, with regional supplements.
The Canadian Landscape Standard shows your clients that your work meets a nationally recognized standard. Industry will be able to refer to the standard during the bid process. It is intended to be user-friendly, available in both hard copy and digital formats. The Canadian Landscape Standard will be a living document that will continually be reviewed and updated to remain current. A subscription will keep users updated as new sections are available and revisions are made.
CNLA and CSLA would like to recognize the BC Landscape Standard Committee, consisting of volunteers from the BC Landscape & Nursery Association, and BC Society of Landscape Architects, who worked diligently over the last 20 years to create the BC Landscape Standard, and who allowed the BC document to be adopted nationally. A legacy page in the Canadian Landscape Standard acknowledges their immeasurable contribution to this new document. A national committee consisting of representatives of CNLA and CSLA has put in many hours to ensure that the Canadian Landscape Standard is a tool that can be used across the country. In addition, many reviewers across the country examined specific sections in depth to ensure national application.
