The Colorado Avalanche locker room has seen several players tie the knot over recent offseasons. Whenever players like Gabriel Landeskog or Cale Makar share team party moments, MacKinnon appears in sharp suits alongside Walker. Unverified social media accounts periodically screenshot these reception pictures, cropping out the actual bride and groom, which spawns rumors that MacKinnon held a secret ceremony.
Close friends in Nova Scotia confirm that MacKinnon enjoys celebrating peers without turning the spotlight onto himself. When he returns home to Atlantic Canada during July and August, his days revolve around morning training, afternoon golf rounds, and quiet time with family. Neither county registry archives in Halifax nor municipal records in Colorado contain a marriage certificate for the couple.
