All three women claim they were drugged and sexually assaulted by Cosby, at various times in the '80s and '90s.
Allred expressed her support for upcoming protests in Kitchener, Ont., where Cosby is scheduled to appear Wednesday night.
A scandal-plagued Cosby is set to return to the stage for the first time since November, with some ticket-holders vowing not to show up and others saying they will heckle the comedian.

The 77-year-old comedian is scheduled to appear at the Centre in the Square in Kitchener, Ont., on Wednesday, at the Budweiser Gardens in London, Ont., on Thursday and at the Hamilton Place Theatre in Hamilton on Friday.
"I don't know how people in good conscience can go and enjoy the show," said Maureen Dragasevich.
Dragasevich, 59, said she and her family bought tickets and were once huge fans, but they're not going now.

Since November, at least 15 women have come forward with claims Cosby sexually assaulted them decades ago. Most of the women say he drugged them before he assaulted them.
Cosby, who starred as Dr. Cliff Huxtable on The Cosby Show from 1984 to 1992, earning a reputation as "America's Dad," has never been charged in connection with any of the allegations, and through his representatives he has denied them. A 2005 lawsuit by a Pennsylvania woman was settled before it went to trial.
Cosby's career unravelled after his accusers came forward, with a TV project halted and at least 10 standup comedy tour performances cancelled or indefinitely postponed. The show in Kitchener will be his first show since Nov. 21 in Melbourne, Fla., where Cosby was greeted by an adoring audience that laughed so hard they slapped their knees, shouted love at the stage and rose to their feet as he came and went. Protesters didn't show and there were no hecklers.
Ontario mayors and premier speak out
Not so in Canada, where protests are planned. Megan Walker, executive director of the London Abused Women's Centre, said there will be a demonstration outside the London venue, and was told some ticket holders who couldn't get a refund will heckle Cosby instead.
Kitchener Mayor Berry Vrbanovic said he will attend an alternative event that was organized to raise awareness of sexual assault at the same time as Cosby's show.

"Until those are sorted out I certainly would not go to a performance," Wynne said.
Cosby's promoter, Adam Epstein of Chicago-based Innovation Arts & Entertainment, said he is legally obligated to move ahead with the shows in Canada, and said it would send the wrong message to other artists if he cancelled.
"If the allegations are true, of course I find them abhorrent, but at the same time at this point I find it presumptuous for anyone to expect me to take action and break an agreement with another business client at this stage," Epstein said. "What if it is not true? If there's an indictment and conviction that's one thing."

Scott Warren, the general manager of the Hamilton Place Theatre, said the theatre is bound by a contract with the promoter and would risk being sued if the show were cancelled.
Don Jones, who has promoted Cosby shows in London previously, estimated the promoter is on the hook for half a million dollars for the three shows.
"That's a lot of money to lose if you decide to cancel. He's caught between a rock and a hard place," Jones said. "To be honest I'm amazed Cosby hasn't cancelled just for the embarrassment part of it."
But Jones said Cosby probably has his reasons.
"He's 77 years old. I've heard that there's about 17 shows left in the schedule. I'm sure he realizes that it's over. I can't imagine any venue buying a Cosby show in the future," Jones said.
