The manufacturing industry in the Montréal region has not much developed over the past ten years and is severely affected by the present economic crisis. A great number of jobs have been lost in the slow sectors. Despite efficiency in transportation equipment manufacturing, many key activities such as steel industry, petrochemistry, electronics and the pharmaceutical industry seem to be in a precarious situation. From a spatial point of view, the weakening of industry in the central city and its net migration to the suburbs continue to profit those locations which have developed their infrastructures during the preceding period. This tendency has confirmed local functional specializations. In order to prevent a further and costly decline, the City of Montréal has been developing since 1979 a comprehensive revitalization program in the manufacturing industry.
