I am not really expert in the area, Mr. Bachand, but I can tell you that CP-140 radars have the ability of detecting submarines. Your question is directly related to the identification of the type of submarine. I am not an expert in this area, and there may be Canadian capabilities I'm not aware of.
At MDA we do provide sonar capability to detect and draw the nature of the bottom of the sea. We have this technology, but I'm sorry, I'm not familiar with identification of submarines.
