Durham Regional Police have called an 11 a.m. ET news conference, but a release announcing it says police have no significant updates in the case.
The 52-year-old Boucher is an avid runner and his family believed he had gone out for a morning run, but he didn't return.
Extensive searches of wooden areas around the Boucher home have failed to turn up any sign of the married father of two.
Police aren't ruling out the possibility the Bowmanville High School teacher met with foul play or walked away from his life. There has been no activity on his bank account and he doesn't have his passport.
Durham police Insp. Nick Lisi says investigators will "take stock" of their efforts to locate Boucher and
review where the investigation goes from here.
Lisi said it's possible a decision could be made to end the search, but adds there is still "so much ground to cover."
Teams of police officers and volunteers have checked and rechecked several kilometres of rough terrain around his home 55 kilometres east of Toronto, with a wider radius searched by air.
These efforts, however, have produced no solid leads.
