I am curious, as I'd like to ask the following question: "Where to find GIS related RFPs online for Canada?"
My reaction is no, for two reasons:
(1) Localization in space and time.
(2) Such questions aren't really about GIS, but about the business of GIS.
I'm sympathetic about the overlap with GIS per se in #2, and have been glad to see some good threads here that are related to GIS business development, but I think that the appearance of transient threads solely seeking to develop business would cross the line into material that would, overall, be detrimental to the site.
An alternative question that might find a home here--but would still be pretty marginal, IMHO, could be something like "what methods do people use to identify/develop GIS consultancies/professional contacts/business opportunities?" In this form, at least, the question would not immediately be closed for reason #1.
