Nuclear-weapon endorser

Did not participate in TPNW negotiations

Has not yet joined TPNW

Canada supports the retention and potential use of nuclear weapons on its behalf, as indicated by its endorsement of various alliance statements of the North Atlantic Treaty Organisation (NATO), of which it is a member.

Canada has not yet signed or ratified the Treaty on the Prohibition of Nuclear Weapons. It did not participate in the negotiation of the treaty at the United Nations in New York in 2017 and thus did not vote on its adoption. 

In a statement in Geneva in February 2018, the then-minister for foreign affairs of Canada, Chrystia Freeland, said that the “popularity” of the treaty “speaks to the desire of countries, activists, and communities to accelerate the work toward disarmament” and “reflects frustration and disappointment at the pace of global efforts so far”.

Canada’s New Democratic Party and Green Party have criticised the Liberal government for its failure to sign the treaty. The government voted against a parliamentary motion in 2017 urging it to sign the treaty.

Several Canadian cities, including Toronto and Vancouver, have urged the Canadian government to sign and ratify the treaty.

Setsuko Thurlow, a renowned disarmament campaigner and survivor of the atomic bombing of Hiroshima, who jointly accepted the Nobel Peace Prize awarded to the International Campaign to Abolish Nuclear Weapons in 2017, has repeatedly called on the Canadian government to change its stance.

Seven former Canadian prime ministers, foreign ministers and defence ministers – namely, Lloyd Axworthy, Jean-Jacques Blais, Jean Chrétien, Bill Graham, John Mccallum, John Manley and John Turner – were among the signatories to an open letter in September 2020 calling on current leaders to “show courage and boldness – and join the treaty”.

Canada voted against a UN General Assembly resolution in 2019 that welcomed the adoption of the treaty and called upon “all states that have not yet done so to sign, ratify, accept, approve, or accede to the treaty at the earliest possible date”.

In 2016, Canada voted against the UN General Assembly resolution that established the formal mandate for states to commence the negotiations in 2017 on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.

In a “non-paper” sent to NATO members ahead of the vote, the United States “strongly encourage[d]” members, including Canada, to vote against the resolution, “not to merely abstain”. In addition, it said that, if the treaty negotiations do commence, allies and partners should "refrain from joining them”.
