Ritz recently announced his retirement from federal politics. His last day in Parliament is Oct. 2.
He was one of the most enduring members of Stephen Harper's cabinet, serving as agriculture minister for eight years until the Conservative government was ousted in 2015.
In 2008, during a listeriosis outbreak tied to Maple Leaf meat products that killed 22 people, he famously joked: "This is like a death by a thousand cuts. Or should I say cold cuts."
When informed of a recent death in Prince Edward Island, he said he hoped it was Liberal MP Wayne Easter.
