Scott Johnson, 33, was killed and three other stage workers injured last Saturday when a roof collapsed over the stage before the band's concert was to begin in Toronto.
The show, which was the final concert of an 11-date North American tour, was canceled.
"Whilst we all are dealing with the grief and shock ensuing from this terrible accident there are also many practical considerations to deal with," E! News reported the band said in a statement Thursday, explaining how elements for the band's elaborate light show were also damaged in the deadly mishap.
The musicians said they are rescheduling several upcoming concerts in Italy, Germany and Switzerland while they regroup.
"We aim to announce the new dates for these shows on Wednesday, June 27 and will also supply information on how to obtain refunds if you cannot come to the show on the new date," the band's statement said. "We will make every effort to offer the fans the very best show possible under the circumstances -- thanks for your understanding and support."
