There may be some strange laws in your province, but we’re pretty sure it’s illegal to do a project that destroys your neighbour’s property. “From a DIY cement wall collapsing on a neighbour’s driveway to repairing an above ground pool that collapses and floods a neighbour’s basement, I’ve seen it all,” says Robert R.
