摘要：This article provides an analysis of various aspects regarding the situation of brownfields in the territorial system of Ottawa – Gatineau, in Canada, which developed considerably from an economic point of view over the last 60 years. The brownfields located in the National Capital Region share a historical / patrimonial significance, but also contain a possible economic value that cannot be neglected. Thus, balance between the economic imperatives of the 21st Century and the heritage elements of these sites must be found in order to achieve the requirements of a sustainable development of the city. Nine brownfields have been identified and analysed, most of them being reintroduced in the economic flow, which led to a considerable amount of positive outputs to the community, eventually contributing to the reduction of urban expansion and to the improvement of the quality of life within this ever-growing urban environment. Reusing these sites for various purposes aims at achieving social, cultural and economic goals set by the administration of the city since the introduction of the Gréber Plan in the 1950’s. Brownfield rehabilitation can thus be considered as possible antidote to the erosion of the urban fabric, but not without some ever increasing challenges.
