Yes, in fact the endurance and the long range that the Royal Canadian Air Force has requested as a requirement for this aircraft would be met by the P-8.
Canada is a big country, so the RCAF wants to be in a position to be able to do the surveillance missions, intelligence missions, and command and control missions definitely within Canada. As well, the Canadian Armed Forces are often called upon to interact with allies abroad. The Indo-Pacific region is one of them. The P-8 would meet the range requested by the RCAF.
