Canada's foreign affairs minister issued a strongly-worded condemnation of what he called North Korea's "provocative ballistic missile test" on Wednesday.
"Canada unequivocally condemns North Korea's provocative ballistic missile test," Minister John Baird said in a statement.
"North Korea's reckless actions clearly demonstrate its wilful defiance of its international obligations, outlined in numerous United Nations Security Council resolutions.
"The regime in Pyongyang is a grave threat to the security and stability of the region and beyond.
"With this latest launch, the rogue regime has once again shown total disregard for its people by choosing to fund military and nuclear programs while the basic needs of the North Korean people go unmet."
Baird urged North Korea to stop its "reckless behaviour" and to live up to its international commitments. "Canada stands with the international community in condemning this reprehensible act," he added.
North Korea confirmed the launch of a long-range rocket earlier and said it had succeeded in its mission of placing a satellite into orbit.
A previous launch of the same Unha-3 rocket in April had ended in failure, with the carrier exploding shortly after take-off.
Washington and its allies have long insisted such launches are disguised tests for an intercontinental ballistic missile capable of carrying a nuclear warhead.
