Welcome to WW, ElmiraGuy.
Here's a page with ward maps that shows their boundaries:
Ward Information. I can understand your confusion, if not your embarrassment. The latter belongs to the City of Waterloo and/or your local councilor for not automatically sending you and all new residents a "welcome package" that answers these sorts of questions.
As for pro-LRT and pro-pedestrian/cycling candidates I too am waiting with bated breath to hear the sales pitches. I'd imagine that as in the past, there will be all-candidates meetings in each ward.
