It used to be done here in Toronto a lot, particularly at subway stations. When I pioneered I got about half my time doing street work. For several years I didn't see it done at all, but since July I see half a dozen JWs every day walking along Bloor St, usually in pairs. The magazines are usually rolled up in their hands and they're talking to each other. Only once did I see them actually talking to someone other than another JW.
