Rogers moved to Toronto, Ontario, in 1961 to work on a new series based on The Children's Corner, called Misterogers, a 15-minute program on CBC Television. Misterogers aired on CBC for about four years and a number of the set pieces that he would take with him back to the United States, such as the trolley and castle, were created for the Canadian program by CBC designers and in collaboration with producer Bruce Attridge. Most importantly, Rogers appeared on camera in the new show rather than only appearing through puppets or characters. Fred Rainsberry, head of Children's Programming at CBC, persuaded Rogers to appear on camera in the new show (which he named after Rogers) after seeing him interact with children. Ernie Coombs, one of the Americans whom Rogers brought with him to help develop the CBC show, would remain with CBC after Rogers returned to the United States. Coombs first appeared as Mr. Dressup in the CBC program Butternut Square, conceived and produced by Attridge. Coombs then helped to develop what became Mr. Dressup which ran for nearly 30 years, ending in 1996.
