Not sure how bad your water is in Canada, but in California more so Southern California the water can be almost horrible due to the high demand. That's why most people either buy bottled water or have some type of water filter in their home. I drink bottled water and have an R/O filter that I hooked up in the kitchen in case I need water for cooking.
Chlorine is typically no longer used to treat water because it breaks down quickly and can combine with certain organics (that may or may not be present in your water) forming trihalomethanes, a family of carcinogens. The new chemical used is called Chloramines, a compound containing both chlorine and ammonia, is much more stable than chlorine. If your water company has switched over to using Chloramines the chlorine portion will break down in 24 hours or less, but you will still have ammonia in your water that is toxic to root hairs and will stunt growth of a seedling.
In addition to Chloramines your water company may have added chemicals to make the water more acidic because lead dissolves less readily in alkaline water. In addition the water could contain nitrates, phosphates, iron and can even be reclaimed water that contains large TDS levels that cause calcium and salt build ups.
If you must use tap water pick up a bottle of Amquel from your local pet store. This will instantly detoxify all ammonia, chlorine, and chloramines in a matter of minutes and only requires a few drops per gallon so you no longer have to sit and wait to use your water.
