In September, 2008 the Canadian government, to the surprise of parliament, decided to buy two types of drones from Israel Aircraft Industries. They will buy the Heron 2 and the Heron TP drones for delivery and deployment in Afghanistan in February, 2008.

The Canadian DND has announced it will lease several Herons at a cost of $95 million, to be delivered in February, 2009, and in the interim will lease several small Scan Eagle drones, at a cost of $14 million.

This was a change from the previous French drones that Canada used. It was also a rejection of the earlier proposal to purchase Predator drones armed with Hellfire missiles from the US.
“We generally insist on a degree of oversight, legitimacy, adherence to the laws of war that require a man in the loop pretty definitively. So it would be a bit of a stretch for us.” Lt. General Angus Watt, as quoted in: Canada in Market for Unmanned Drone Aircraft, CTV.ca, 6/10/2007
Watt was discussing the uncomfortableness that the Canadian military would have operating an attack drone armed with Hellfire missiles from a remote setting in Nevada or elsewhere. See also
One blogger claimed a rumour, without any substantiation, that a Canadian cabinet minister with a habit of boosting Israeli interests, had managed to nix the Predator purchase, and get the Herons substituted. The Torch, 26 May, 2008
