In the US it's not really legal to ask about a job applicant's car or whether they have one, unless the job involves driving. Not that it always stops them from asking. I don't know about Canada.

But in my current job it did come up in the interview, whether biking that distance might be a problem getting to work. It may have been just curiosity because we honestly don't care here, as long as you show up, but I'm pretty sure that it worked in my favor.
