Canada uses Leopard 1, not Leopard 2, so they don't even have a modern battletank.
In the Balkans, a potential opponent for CF Leopards was the M-84 (a Russian T-72 license-built for the Yugoslav Army). At least as fast and well protected as a Leopard C1, the M-84’s main armament (a smooth-bore 125mm semi-automatic cannon) seriously out-gunned the Canadian tank. One trial conversion replaced the C1’s standard L7A3 with a Royal Ordnance IWS 105mm main armament. But plans to convert all C1s were eventually abandoned. Another promising candidate is Rheinmetall’s new smooth-bore 105mm gun. Rheinmetall now proposes up-gunning the MGS with the new design since CF Leopards are to be mothballed and Canada will be out of the tank business
The only modern armor they have
