Asbestos was used in many forms over the years. In fact Canada still exports asbestos to other countries. The majority of the asbestos in your home is likely either in your attic insulation or your flooring. In order for asbestos to be dangerous it must be friable or floating around the air where it can be breather in. Asbestos only affects the lungs so you must do your best to not breathe in high concentrations of asbestos fibers. If you suspect you have asbestos you can have it tested. I can send samples away to a lab in Ontario where the quantity and type of asbestos can be identified. I usually suggest the customer simply stay away from the asbestos containing material but if this is not possible you need to take precautions. Visit my website for more on this topic.
