Canada, like Australia, had only NDB approaches at most airports until very recently.
Thankfully Transport Canada (CAA equivalent) has finally started getting serious about commissioning GPS approaches at all instrument airports.
I started carrying a handheld GPS in the early 1990's and now all the aircraft I fly have proper IFR GPS units fitted. As near as I can figure the last time I flew a for real IMC NDB approach without some sort of GPS track guidance, even if it was only the handheld, was 1994
Now of course if I was using a handheld the primary nav instrument was the ADF but amazingly after 1994 the aircraft track was always very closely aligned with the centerline of the runway when I broke out on the "NDB" approach
Before that the runway was anywhere from 10 to 2 O'Clock when I got visual. I guess I must have suddenly got a lot better at NDB approaches in 1994
