An update to this story: On Sunday, March 20, Toronto police said via Twitter that Ashley and Nakita Johnson had been located. 

A Toronto woman and her three-year-old daughter have been missing for about a month, Toronto police say.

Ashley Johnson, 27, and Nakita Johnson, 3, were last seen near Eglinton Avenue East and Birchmount Road in February. 

The 27-year-old stands at about five feet, 10 inches tall, weighs approximately 86 kilograms (190 pounds) and has long, curly dark hair.

Police have checked the residence where the mother and daughter live together and say it appears the pair haven't been home for quite some time.

Family members had been planning a birthday party Saturday for Nakita, who turned three on March 17. Police say relatives have grown especially concerned since the girl and her mother didn't return home in time to celebrate. 

Johnson's close friends and family don't know their whereabouts, according to authorities, who add the situation is uncommon.

"Police wish to locate Ashley to ensure that she and her daughter are well," police said in a statement issued Saturday. 

Anyone with information is asked to call police at 416-808-4100 or Crime Stoppers anonymously at 1-800-222-8477.
