The Liberal government has said it wants to restore diplomatic relations, even after Iran arrested retired Canadian-Iranian professor Homa Hoodfar, who was after months in Evin prison.
Until then, Sadri said he will continue to mourn Seyed-Emami's death and remember his passion and love for the outdoors and hiking.
On Instagram, Raam said Iranian authorities said Emami had committed suicide in jail.
"A group of those who gathered strategic intelligence and handed it over to foreigners have been identified. The case is at its initial stage and details can not be disclosed", Gholamhossein Esmailie, the head of Tehran's judiciary department, told ILNA on Sunday.
A friend of an Iranian-Canadian academic who died in an Iranian prison disputes Tehran's claim that he took his own life.
Mr Seyed-Emami ran the Persian Wildlife Heritage Foundation and was a sociology professor.
Mr Emami's friend and former sociology colleague at the University of Lethbridge said his death was a "profound tragedy".
'The information published about him is not believable, and we expect officials to respond and to provide the public with information concerning his death, ' it said.

"The incomplete and vague information of the Tehran prosecutor added more questions".
There is now no Canadian embassy in the country and there are no official diplomatic relations between the two nations.
Ghaemi said Seyed-Emami was a founder of the group, which he called "the leading environmental NGO in Iran", and he was detained along with almost a dozen other members.
