Ritchie Bros. Auctioneers is a marketplace that facilitates the buying and selling of heavy machinery used in construction, mining, forestry, and other industries.

The company held a regional auction in Ontario this week that lasted three days. While bidding took place online, interested parties were able to inspect equipment in-person at three specific sites located around Ontario ahead of the actual auction date. 

Auctions involve a mix used and unused equipment, trucks, and other construction-related consumer items, and take place both in person and online.

This heavy machinery can fetch hefty prices: Each year, the company sells billions of dollars worth of equipment and trucks, according to its website.
