This paper synthesizes Canada's environmental valuation literature over the last six decades. Focusing on primary valuation benefit estimates, we link multiple research outputs from the same data collection effort to obtain an accurate measure of unique studies. We identify a total of 269 unique valuation studies conducted in Canada between 1964 and 2019. The number of valuation studies conducted per year has not increased since 1975 and the median data collection year is 1996. Stated preference (SP) methods are the most popular valuation approaches being used in more than 50% of studies and this share has increased to over 80% within the last decade. We discuss numerous gaps in our knowledge for certain environmental resources and regions, in particular Canada's three Northern territories. The paper provides information on the state of environmental valuation research in Canada and identifies future research needs.

加拿大环境资源评估的六个十年：文献综述

本文综合了加拿大过去 6 年的环境评估文献。专注于主要估值收益估计，我们将来自同一数据收集工作的多个研究成果联系起来，以获得对独特研究的准确衡量。我们确定了 1964 年至 2019 年间在加拿大进行的总共 269 项独特的估值研究。自 1975 年以来每年进行的估值研究数量没有增加，数据收集年的中位数是 1996 年。陈述偏好 (SP) 方法是最受欢迎的估值超过 50% 的研究使用了这些方法，并且在过去十年中，这一比例已增加到 80% 以上。我们讨论了我们对某些环境资源和地区（尤其是加拿大的三个北部地区）的知识上的许多差距。
