The Engineering Seismology Toolbox (http://www.seismotoolbox.ca) is a virtual laboratory that provides processed seismographic data, including time series and spectral information. A variety of programs and tools for signal processing and various applications are also provided. The products of the toolbox are updated continuously and are freely available to all researchers. A key resource provided by the Toolbox is a database of processed time series and Fourier and response spectra for moderate earthquakes recorded on seismographic stations across Canada. We describe herein the data available in this online database, and provide an example application of the database to study of the ground motions from the 2005 MN (Nuttli magnitude) 5.4 Riviere du Loup, Quebec, earthquake.
