After a thorough internal investigation at an Ottawa Ikea store, the Swedish furniture chain says it cannot find evidence of an alleged breastfeeding incident in which a mother says she was called "disgusting" by a staff member.

Ikea spokesperson Madeleine Lowenborg-Frick said Saturday that the store's security footage was "carefully" reviewed and employees working at the time of the alleged incident were all interviewed.

She said the in-depth investigation into the allegations made by Ottawa mother Brea Rehder has turned up no evidence of an altercation. For her part, Rehder is standing by her account of the interaction.

"Even when we did find her on our security footage, there's no evidence of the interaction she's described. In fact, at no time can we see her breastfeeding her baby," Lowenborg-Frick told CTV Ottawa on Saturday.

The internal investigation was launched after Rehder said she was called "disgusting" by a store manager for nursing her nine-month old daughter while she waited in line.

Rehder took her complaint to Ikea's Facebook page, where she wrote that she had "never been more insulted" in her life. Her post garnered a lot of attention, with some nursing mothers saying they would take their business elsewhere.

However, Lowenborg-Frick said the security footage shows that when Rehder was going through the checkout at Ikea, her nine-month-old was not with her. She said the baby was sitting in a highchair in the store's bistro with a person accompanying Rehder.

Lowenborg-Frick added that Ikea is "absolutely positive" of its position. "We would not publicly go forward if there was any doubt."

She said the investigation was difficult on the staff at the Ottawa store.

"At the end of the day, finding out that this incident actually didn't occur, it's not great for our co-workers to have their employers question their integrity."

Ikea said it tried to contact Rehder but hasn't been able to reach her.

On Saturday, Rehder stood by her original account in response to Ikea's investigation, saying in a statement she has "nothing to gain from falsifying anything."

In response to Rehder’s complaint, a "flash feed-in" of nursing mothers has been scheduled at the Ottawa Ikea store for Sunday at noon in the living-room section.

According to the event's Facebook page, the "flash feed-in" was organized to "thank" Ikea for supporting nursing mothers.

"While the story surrounding the incident last weekend in which a woman was publicly shamed for nursing horrified many, it was encouraging to hear of Ikea's speedy response," a message on the group's Facebook page said."This isn't a protest, but rather a thank you."
