Vancouver does have significant conferences, for example the GROW conference in August had a pretty high-profile list of speakers and attendees. There have been at least a dozen or so companies in Vancouver who've raised VC rounds this year.
Almost all successful startups and tech companies will have connections to VCs (regardless if they were venture funded or not), so one good route would be to network with the founders of the successful startups in Vancouver and get introductions to VCs from them.
