It’s a free fishing weekend. You can spend the Family Day holiday, trying your hand at ice fishing from Saturday through Monday. You can fish any water-body that has an open sport fishing season without buying a licence. All other regulations remain in effect, including possession limits and reduced limits on some lakes and rivers. Free fishing weekend does not apply in national parks; and, anyone planning to take fish out of the province, must buy a licence. You need 10 cm of good ice for walking and 30 cm for light vehicle traffic.
