The service for Pascal Gosselin will take place in La Prairie, just south of Montreal.
The 46-year-old is survived by his wife, their three children, his parents and a sister.
A funeral for Lapierre, his wife, his two brothers and one of his sisters will be held on Friday in Bassin, the late political commentator’s hometown in Iles-de-la-Madeleine.
They all died when the plane crashed on March 29 as it approached the airport in Havre-aux-Maisons. Friday’s funeral will also be for Lapierre’s father, who died of Parkinson’s disease a few days before the crash.
Details of the funeral for the seventh person to die in the accident, co-pilot Fabrice Labourel, are not known.
