My first post so please be gentle with me!
I think the lady’s name is Helen Harrison. She was indeed Canadian and has an extensive entry in the dreaded Wikipedia.
Really a remarkable career; b 1909 : d1995.
She got her A licence in 1935 here in Britain, took further instruction in South Africa and, back in Britain, became one of the first women to become a qualified instructor.
She gets an honourable mention in Giles Whitwell’s book Spitfire Women which I found both informative and occasionally moving. Apparently Helen had a real reputation as a party animal and an remarkable capacity for alcoholic beverages! Some of those ladies were quite amazing.
Helen had flown more than 14000 hours by the time she retired.
