I'm wondering if anyone has the logs for HMCS Niagara (for 1942 and 1943) and for HMCS Prince Rupert for January 1944 until May 1945.

I am trying to determine how many Atlantic crossings each of them made during those periods as well as the times and dates that they may have dropped depth charges on suspected U-boats (not counting Prince Rupert's well known attack on U-575 on 13 March 1944).
I am interested because a friend, now dead, served on the two ships during those time periods and I am researching his naval career.
