In Ontario, just because the assessed value of your property goes up doesn't mean your taxes also go up. It is whether your property has increased more than the average increase for the city. I presume Vancouver must have the same sort of system. 

If you want to argue for a different way to calculate property taxes (square footage of the property, for instance) you can, or abolishing property taxes altogether, you can. 

But the money to pay for municipal services has to come from somewhere.
