The canister of undeveloped film was found on a roadside near Victoria, British Columbia, this month by Helen Maslyk, who had stopped her car to deal with a tire problem. She had the film developed and posted the photos on Facebook to find the owner, the Canadian Broadcasting Corp. reported Tuesday.
The photos, lost during a vehicle break-in, were discovered by their owner Ann Perry-Smith.
"My jaw just dropped. There's a picture of my husband, my baby who's only weeks old at the time, and my dog,' she said.
Perry-Smith said her daughter, now 9, was happy but not surprised that social media brought the family and the photos together.
