Better coordination would certainly improve the situation and wait times. It's like taxation. In Quebec, we have the privilege of having dual filing. The same is true of immigration. In Quebec, we have the privilege of having a dual system, with acceptance certificates and then federally issued permits. That can cause additional delays in the process, so some people are choosing to settle outside Quebec because of the delays happening in Quebec.
That said, I think we need better co-operation. There's a more political dimension at play here, so it's important to look at how the two governments can work together better. Quebec is very cautious when it comes to its jurisdiction over immigration, which it wants to hold on to. Better co-operation is needed in order to reduce the delays. I completely agree with your observation.
