That's a very broad question, and I wouldn't be able to do it complete justice.
At the tactical level, there is an enterprise that exists on the ground. It's called Combined Joint Task Force-Operation Inherent Resolve. The nations that form that coalition share intelligence. Intelligence is created and shared at the tactical level. That's all governed by how we are allowed to share Canadian intelligence, information sharing agreements, etc., which we follow rigorously and to the letter. Intelligence is also shared within more bespoke groups, like the Five Eyes coalition.
