Adam will answer part of that, but I would say that it is not fair to say that costs have increased on roads, etc., at around inflation rate and property tax has increased by inflation. The demand on the property tax has increased more than inflation, because more things have been downloaded onto municipalities as their responsibility. So the property tax is now serving a lot more services and expectations of the citizen than was the case when it was originally conceived or was the case in 1985.
For example, if you take a look at a report we did a year or so ago about the social safety net in Canada, you'll see there are a lot of issues in that report that are about municipalities delivering services that are now part of the social safety net, which were never conceived of to be part of the property tax base. So there is an expanding demand on the property tax base.
