At the Canadian War Museum they have a 155mm artillery piece. Similar to those donated by Canada to Ukraine.

The museum also holds lots of examples where Canada intervened. Eg:Kosovo.
Pity Canada, and other countries do not intervene in Ukraine. Up to 100 Ukrainian fathers, a day, will not be coming home. Targetting by Russian drones. With Russian artillery, rocket, cruise missiles, and aircraft strikes, being the main cause of death.
Closing the skies would help save fathers, brothers and sons.

Happy Father’s Day?
Maybe after Ukraine has secure skies, and serious long range weaponary. The longer range weapons could target aircraft at their bases, the launch vehicles for the cruise missiles, and the drone operators.
