A Canadian Senator known for being tough on terror and working to end the gun registry announced his resignation Thursday.

Senator Daniel Lang, a Conservative who represents Yukon, announced he plans to retire on Aug. 15.

“It seems like yesterday when I arrived and one of my first orders of business was to sponsor in the Senate, the repeal of the long gun registry which was so detested in rural and Northern Canada,” Lang said in the Senate Thursday morning.

Lang was appointed by Stephen Harper in 2009 and did not face mandatory retirement until 2023.

Prior to entering the Senate, he served five terms in the Yukon Legislative Assembly from 1974 to 1992.

Recently, Lang was a strong critic of Liberal Bill C-6, proposing amendments to toughen the bill that was widely seen as soft on terror. Writing in a Sun guest column, Lang commented: “I am most concerned about the radical liberal view that once a dual national is granted citizenship, Canada should not revoke it, especially if the individual is convicted of a serious terrorist offence.”

During his time as Chair of the Standing Senate Committee on National Security and Defence, Lang helped bring to light the number of Canadian jihadists that the RCMP and CSIS knew about as well as the shocking news that they weren’t being charged.
