I've done the same (US employee going to Canadian office).

Interestingly enough, me and my colleagues were pulled aside for additional questioning because two of us didn't own cars (we both live in Seattle and bus everywhere). For some reason the Canadian border agent simply didn't believe that people in the US don't own cars! We were able to go through after the manager of the team we were going to meet had been called to verify our story.
