It might seem that because the property tax is rooted in physical land use, it would be insulated from technology-led disruption. There is no single, big, obvious technological force we can point to as a disruptor, as we can for hotel taxes and Airbnb or sales taxes and online retailing, but many less obvious 21st-century technological forces are conspiring to reduce the relevance of property taxes, which have been in use in North America since at least the mid- to late 1600s. The Region of Peel, Ontario, recognized this disruption and decided to do something about it.
