Police have found a shoe they believe may belong to Jeffrey Boucher, the Whitby, Ont., teacher missing since January.
Durham Regional Police said the shoe was found along the shore of Lake Ontario in Whitby, which is located 55 kilometres east of Toronto.

Police said a woman walking near Heydenshore Pavilion on Tuesday found the shoe and contacted police.
Further investigation led police to believe the shoe belongs to the 52-year-old father of two teenage daughters, who left for his usual early morning jog on Jan. 13 and has not been seen since.
In the days after Boucher's disappearance, police conducted an extensive ground search of wooded areas near his home. Boucher, a teacher at Bowmanville High School, is a fitness enthusiast and usually took long runs most days, often varying his running route.
In February, police used an underwater camera to check out a section of Lake Ontario in Whitby, but had to call off the search due to high winds and cold temperatures. On Feb. 2, Boucher's wife Kristen told CBC News she believed her husband was dead.
Police are assessing ground and water conditions in preparation for a search they say will start next week. Police also plan to carry out an aerial search Friday at 6 p.m.
Boucher is described as white, six feet tall and 180 pounds with grey and white short hair.
