YUL is much improved from just a couple of years ago. Security is less congested and many domestic flights leave from the higher numbered gates to the left of security. Better food service choices but still no Amex lounge. The entrance is still congested so there is sometimes a wait to get from your cab to the entrance. Wait time for taxis is still long. Try the 747 bus so at least if you have to sit in traffic it's not costing much.
