The card read: "In lieu of a favor, a donation has been made to Hockey Fights Cancer in loving memory of Deme Anas. We feel the greatest gift is one which helps others living with and moving past cancer. We truly appreciate your being part of our special day."
Anas tweeted that it was an "incredible gesture" and that Toews is "always thinking of others even on his big day."
Each November is Hockey Fights Cancer month across the NHL. Through a partnership with the American Cancer Society, Canadian Cancer Society and Movember Foundation, donations to Hockey Fights Cancer support people affected by cancer, their families and caregivers.
