There is an old adage derived from the theory of wealth condensation that money begets more money. However, throw this out the window in the world of academia. Awards such as SSHRC and OGS may help you're chances but they by no means guarantee you additional funding in later years. OGS and SSHRC are fucken popularity contests, it all depends on if the committees have a hard-on for your study. If your proposal does not fall under the category of flavour of the month then any previous grants will not help your chances. As I have said to many people in the past, don't let OGS or SSHRC grants go to your head, they are not indicative of your overall abilities or of your potential to secure prospective grants. I received SSHRC two years again and have been since twice rejected for OGS and SSHRC respectively. So don't rest on your laurels, work on your proposals and get publications out there, those are your best chances of getting funding. OGS don't mean shit!
