Donna Guillemin says her mother's bus was running late on Saturday but instead of waiting inside the station at Castlegar, she was asked to wait outside because the station was closing.
"She was just left outside in the cold without a chair or a bench," Guillemin said.
"It's just not that safe. It's not what we would want for young people waiting for parents or old people."
Guillemin says her mother was told she could wait at a coffee shop up the street.
Greyhound spokeswoman Alexandra Pedrini says the company was in the wrong.
"Unfortunately the situation wasn't handled the way it should have been," she said. "And for that we sincerely apologize"
