Suspect in Ottawa hotel threat could have chemicals: RCMP

A man suspected of making a threat at an Ottawa hotel could have travelled from Nova Scotia with chemicals like those found in a Cole Harbour, N.S., home, RCMP say.

Twenty homes in Cole Harbour were evacuated after a suspicious package containing hazardous chemicals was found in the garage . Later, an evacuation order was issued in Grand Desert, and it remains in effect.

Ottawa police evacuated the Chimo Hotel in Ottawa on Tuesday night and closed off the surrounding area after receiving a threat by a man they believe had checked into the hotel.

Police said they were called to the hotel at 1199 Joseph Cyr St. at about 10:15 p.m. ET.

Both the police hazardous materials team, and the chemical, biological, radiological, nuclear and explosive team were called to the scene.

The hotel was evacuated as a safety precaution, police said.

Police believe the man suspected of making the threat is in the hotel and are searching for him, but say they have not yet made contact with him.

Ottawa police would not confirm whether the possible threat was linked to any other police investigation. But Nova Scotia RCMP told CBC News the investigation was linked to the two evacuation orders issued in Nova Scotia on Tuesday.

Police in Ottawa have closed the following roads while they investigate:

- The Highway 174 St-Laurent off ramp is closed.

- Joseph Cyr Street is closed from Cyrville Road to Lemieux Street.

- Lemieux Street is closed at St-Laurent Blvd.

- Labelle Street is closed from Lemieux Street to Michael Street.

- Michael Street is closed from Cyrville Road to Labelle Street.
