Where can I find stock prices for delisted companies?
Canadian companies are in CFMRC.
Use Datastream, available in library. Using the EXCEL add-in look for the "Find Series" button. Enter the company name. If there are many results use the filter for "Dead" companies in the left margin.
Use CRSP available in the WRDS database. WRDS is available to current Western Master's and PhD students, staff and faculty members.
