OTTAWA -- Canada is bringing in strict measures and fines for recreational users of drones.

Transport Minister Marc Garneau on Thursday announced restrictions to curb the number of incidents in which recreational drones have come too close to planes, which has more than tripled since 2014.

Recreational drone operators must now mark their drone with their contact information and are forbidden to fly them at night or in cloudy conditions.

Drones will no longer be allowed to fly higher than 90 metres (295 feet), within 75 metres (245 feet) of any buildings, vehicles or people, or within 9 kilometres (5.6 miles) of airports.

Violators are subject to a fine of up to $3,000 , and up to $15,000 for corporations.

Commercial, academic and research drones are exempted.
