If the rest of the report is like these 2 paragraphs, no need to read the rest . we already know.
Am I correct in assuming that the report is not going into details as to why communications failed between the Civil ATC part and the Air defense unit responsible for the coordination ?

Does the report say anything about how there had been a whole string of departures in the previous hour on the same track, but this was the one shot at..

Here is a link to the full report (made available by the CTSB, Canada). English version begins on page 140:

I believe you're looking for pp. 75-76. Presumably, after a round of scanning for threats, the mobile SAM scooted about 100m at 4:54 AM, and went into Standby mode. They changed their direction, but did not reset north, resulting in a 105-degree error. They switched the radar on again at 6:07, and acquired a target at 6:14, apparently bearing 250 and heading 56, but actually bearing 143 and heading 309. At 6:14:19, they reported the contact to the Coordination Center and twenty seconds later fired. According to the Iranian military, which provided this information, the Coordination Center did not receive the call, nor could it be heard on their recordings.

The Iranian government is committed to a safe, effective and efficient civil air transport system......said no one, ever

Uncertain if any abbreviation might exist for the SLF-equivalent of an individual who lacks real, operational knowledge of SAM units or their radars, but ....
If a unit had decided to create facts that possibly would be seen as credible as an explanation for a supposed "error" - as a cover story - would a 105-degree error resulting from failure to "reset north" be a plausible way to set up the cover story?

While this is a tragedy I think it is quite remarkable, that they are finally open about what happened. This is a very good sign after all those lives lost.

I don't think so.....

From the head of Canada's Transportation Safety Board

Reading #660 they clearly blame the military and its risk management. What else could they do realistically? I understand the frustration about that political blame game intro but it's a cvivil government body that finally openly criticizes their own military.

Well he can disagree of course but this is a fact and correct.
I have not finished to read the Iranian report but so far I read the confirmation that the Civil ATC did coordinate the departure with the military sector , so the communication failure(s) were inside the military apparatus.
Procedure to avoid misaligning a missile battery and improving communications between them and their command center fall well outside of ICAO Annex 13.

That said, that the Canadians, seen the number of their nationals on board, feel unhappy with the report one can understand them.
There they have a point, and in fact there lies the main issue. The Sates are responsible to declare a conflict area and airlines decide to fly or not in that area,. Often listening to CNN gives better info that waiting for a NOTAM of the State involved.
Similar situation at the moment with Saudi Arabia . IFALPA just issued a Safety bulletin , urging extreme caution. But if your airline schedule you to go , or, like in this case , to fly back home, what do you do ?

One mystery though , I cannot see why the Canadians were not allowed to have access to FDR and CVR recordings . What can there be in there that is subject to secrecy or that would alter the conclusions. ?

ATC Watcher:

Re your last point. Canada's participation was restricted to only those areas listed under 5.27 of Annex 13, which lists the things that an observer / expert from a State that does not qualify (in that given accident) to particpate directly via the "Accredtied Representative" rules of Annex 13. The relevant section of Annex 13:

PARTICIPATION OF STATES HAVING SUFFERED FATALITIES OR SERIOUS INJURIES TO ITS CITIZENS Rights and entitlement
5.27 A State which has a special interest in an accident by virtue of fatalities or serious injuries to its citizens shall, upon making a request to do so, be permitted by the State conducting the investigation to appoint an expert who shall be entitled to:
a) visit the scene of the accident;
b) have access to the relevant factual information;
c) participate in the identification of the victims;
d) assist in questioning surviving passengers who are citizens of the expert’s State; and
e) receive a copy of the Final Report.

That section omits some of the entitlements for State's "Accredited Representatives" listed separately in the Annex, including the specifc right to be present for the decoding / playing of the various recorders.

Thank you for that explanation , forgot that bit. you are right. , I can guess the relations between the Iranians and the Canadians might have been strained that the Iranians decided tp play by the book.
They are correct but it is rather unusual I would say.

ATC Watcher: I think your comment is right on the money re Iran played this "by the book" meaning doing only what Annex 13 requires and nothing more. As you suggest, that is somewhat unusual as, in my experience, most States allow those additional experts more latitude. And yes, the relations between Canada and Iran have been very strained since 2012 (Canada currently has no diplomatic representation in Iran and vice versa.)

I wonder why for a flight under 1,300 nm and duration about 2hr 45min, departing before dawn, elevation 3,600ft on a recent 737-800, they needed to leave 85 pieces of luggage behind due to weight issues. Aircraft seems more capable than that.

Indictments in Iran re: shootdown of Ukrainian 752
 

Reporting in The Canadian Press today states that in Iran, ten officials have been indicted in connection with this incident. The indicated officials have not been named. The news article refers to other reporting about statements made by an Iranian "military prosecutor" - specifically referring to the "semiofficial ISNA news agency" and the "Iranian judiciary's Mizan news agency."

Article in The Canadian Press also reports statement by Canada Prime Minister Justin Trudeau demanding further accountability, compensation, and justice. Additional statements by others as well.

Iran intentionally shot down Flight PS752 in 'an act of terrorism,' Ontario court rules

Ontario's Superior Court of Justice has ruled that the shooting down of Flight PS752 by Iran was an intentional act of terrorism.

The Islamic Revolutionary Guard Corps (IRGC) shot down the Ukraine International Airlines flight with two surface-to-air missiles shortly after takeoff in Tehran on Jan. 8, 2020, killing all 176 passengers onboard. There were 138 passengers onboard with ties to Canada, including 55 Canadian citizens and 30 permanent residents.

"The plaintiffs have established that the shooting down of Flight 752 by the defendants was an act of terrorism and constitutes 'terrorist activity'..."Justice Edward Belobaba wrote in his decision issued Thursday. "I find on a balance of probabilities that the missile attacks on Flight 752 were intentional and directly caused the deaths of all onboard.”

Iran did not defend itself in court to refute the plaintiff's evidence, making this a default judgment.….The court decision is a way for victims' families in Canada to seek damages from Iran for the death of their loved ones.

Iran was served the claim in the fall of 2020 and was noted in default last December. The justice said the plaintiffs are entitled to default judgment on liability. Another court hearing will take place to determine compensation…..

Arnold told David Common, host of CBC News Network's Power & Politics, that there are Iranian assets in Canada and internationally that he would try to seize, including oil tankers.

"We will be looking internationally to seize whatever it is we can seize once we have a determination of what the level of compensation is," he said…….

"Default judgement" since the defendant didn't meet in court.

I'm not sure about the idea of seizing Iranian property abroad to cover compensation..... that'll bring up a lot of questions about what is possible to do in the future.

Drag the US, or any other country, into court, they do not show, "default judgement" and we start seizing property......

I understand that this is mostly a money grab but quite frankly this judgement is ridiculous in so many ways.

Judgment for Damages
 

The Ontario Superior Court of Justice has issued a second ruling (dated Dec. 31, 2021) awarding damages, based on its prior ruling on issues of liability. The total damages award is $107 million, with almost $95,000 in costs. The estates of passengers killed in the accident were awarded a total of $1 million in compensatory damages for loss of care and companionship, $1 million to each of six estates for pain and suffering, and $100 million in punitive damages to be divided among the estates.

Here is the link to the Court's opinion - without any comment on whether the judgment will be collected or otherwise enforced. And also without prediction or forecast about whether or not it will have any benefit for the diplomatic efforts Canada has initiated and supported since the January 8, 2020 shootdown of Ukraine International Airline PS 752.
