The purpose of this Standard is to document acceptable Canadian landscape construction practices as agreed upon by the CSLA, the CNLA, government authorities and other industry associations.
Updated Version (June 2024) of the CLS is now available!
The Canadian Landscape Standard (CLS) Steering Committee is proud to release a revised edition (June 2024) of the Canadian Landscape Standard, a value of $100, free to CNLA members. This edition contains a new and revised Section 5—Growing Medium and several other updates.
The science of soils is a continually evolving subject, and the CLS is a living document that will endeavour to reflect this evolution. The CLS Committee commissioned Vineland Laboratories to develop a revised Section 5, and a national consultation followed. This is the result of Vineland Laboratories' work, your feedback, and the discussions of the CLS Committee.
