I use a 6 stage BRS RO/DI chloramines unit for Edmonton water. Output is now 0 ppm TDS.

My costco RO only system unit measured 3-7ppm TDS after a filter change. Sounds bad but that's about right for a 97-98% rejection rate. I'm guessing the same Costco unit used in the lower mainland would give you readings of 0 ppm and filters/membranes would last a good deal longer.
