Paul Martin will attend an interfaith ceremony in Ottawa along with other officials and religious leaders, the Canadian Broadcasting Corp. reported.
"I believe this interfaith event will highlight the common spirit among people," said Abdul Rashid, a Muslim leader scheduled to speak at the ceremony.
"It's the living we have to pray for. They need to be strong enough emotionally and physically to stand up to their losses."
Representatives from the Buddhist, Catholic, Hindu, Sikh and Baha'i communities are also doing readings and prayers.
