The RCMP has set up a dedicated witness phone line and email after concluding a fire at Burnaby Hospital last month was set on purpose.
Fraser Health has said the November 15th fire contributed to COVID-19 outbreak declared at the hospital one week earlier.
It says patients had to be moved for their immediate safety and at least 10 people died from COVID-19 during the outbreak.
The hospital's emergency department was temporarily closed and some medical appointments and surgeries were rescheduled.
Fraser Health said the fire started in one wing and affected several other parts of the building.
More than 100 patients and staff were associated with the outbreak and at least 10 people died.
