That statement is incorrect.
The Crown has expropriated land for centuries. The concept of property ownership has everyone turning a blind eye to the unpalatable, but true fact, that the Crown always has and always will take what it wants.
You do not really OWN land, at best you are granted a right of exclusive use with governmental limits on that use, and the government's rights to that land that supersede yours. The word "ownership" is a term favoured by those not wanting you to think about the limits that exist on your rights of possession.
The Expropriations Act in Ontario gives that power to local school boards. The bottom rung of politicians, a step below city counsellors, and they can take your home.
{Unless of course you are a native who has set up a blockade to the casino and the smoke shack, since no politician in Canada possesses a pair of balls you are quite safe and will be left alone}
{Which brings up another aside, if Canadian politicians have no balls do they ever see SP's? }
If you screw up your last will and testament, and have no one in line to get your stuff, it all reverts to the Crown.
Here is an 1886 Supreme Court of Canada case dealing with expropriation of land {another aside is that the Supreme Court was not the highest court at that time}.

This is not a recent thing.
There has been media attention in the last few years as the concept and use of the doctrine of eminent domain has expanded by local governments in the U.S. There are case of homes being expropriated so that a business such as Walmart can set up shop. But it is not new, its just getting a little more attention these days.
Ultimately very few people will change their vote based on this issue so it will continue regardless of what addle minded twerps we elect.
