That report doesn't even mention chloride, and all of the stated levels have a really wide range when it comes to brewing. However, if you take the average values, the "average" Calgary water would be most suited for malty and fairly dark (18-23 srm) beers... which means nothing if there is indeed 3 different water sources.
I would definitely contact the City to get more detailed info about the water coming out of your tap. The City of Regina was very helpful when I contacted them, they gave me month by month averages (most water chemistry changes throughout the year).
