The major event was scheduled to take place from August 6 to 23.
Festival organisers said the unprecedented move to cancel the 2020 edition was not taken lightly.
“The thought of a winter without MIFF in our city is a disorienting one; deeply disappointing to both our organisation and, I’m sure, our community,” MIFF artistic director Al Cossar said.
“It is a decision that was very hard but plainly necessary, responsible and required given what we all face together at this moment.
“Our thoughts rush to those who make MIFF what it is year after year, and what it will return to be.
“To our partners, funders, venues, staff, suppliers, filmmakers and artists, volunteers, prized collaborators of all kinds, and our own uniquely MIFF audiences, we wish you safety and support; we will continue, together.”
According to an official statement, MIFF is considering other means of maintaining its engagement with audiences in the absence of this year’s festival.
The 69th edition of MIFF will now take place in August 2021.
If you have already purchased a membership or a pass to MIFF 2020, it will now be valid for MIFF 2021, and any passes or memberships purchased from today will also be valid for MIFF 2021.
