I get most peoples from Kijiji. That seems to be the best locally for strangers to come. Word of mouth takes a lot of my spaces lucky for me.

When things are quiet or if I have more than one place open up in Septembers, then I use different things to target locals.

I tape flyer to local mail boxes. Have a route that loops about 2km and go every week and check still there.
I do business card under car wiper in local grocery store.
I do flyer at doctor, library, anywhere young parent might be, Play Cafe, Church
I do lawn sign - not really allowed around here but I do it when need to
And I do car magnets on my car door with business name and telephone number.
Lots of different things to figure out what is good locally.

I tried newspaper flyers and local publication but not very much interest from that, for me.
