Seeking help with Royal Canadian Air Force WW2 Missions

Could someone please help? I am looking for information regarding a Royal Canadian Air Force Mission that might have taken place on July 29, 1942.

The specific information I am interested in finding out is -

1.) who were the members of the crew? (I know at least one, Horace Russell Kedwell)

2.) What regiment did they belong to?

3.) What type of place were they flying?

Thank you to anyone who can help!
