A “anti-hail cannon” could be a Canadian first, as a Quebec apple orchard says the device could protect its crops from icy weather.

The cannon has been deployed at Verger des Bois-Francs southeast of Montreal by Maxime Brie. Hail has long been an agriculture producer nightmare as it can bring significant crop damage.

Anti-hail cannons aren’t a new invention for farming, having originated in Europe but are now manufactured in various countries such as New Zealand and Germany.

The Spanish-made one used by Brie is one that he claims has never been used in Canada before. The device cost them $160,000.

They work by causing controlled explosions near the base that then blast shockwaves into the air, which turn hail into harmless water.

By being connected to a weather station run by SPAG, with meteorologists monitoring conditions at all times from a facility in Brazil, it allows the device to better respond to storms.
