LegisInfo provides committee information (e.g. the Standing Committee on Industry, Science and Technology) back to the 35th Parliament, 1st Session (1994).
However if you need to research parliamentary committees prior to this date, you can use the Library of Parliament’s Canadian Parliamentary Historical Resources. These cover the 6th Parliament (1887-1888) to the 34th Parliament (1988-1993).
Unfortunately, while you can view the committee proceedings online, they cannot be downloaded as PDFs at this time.
