Interested in MCounselling Program - using Postgrad Diploma as entry point?

Hello, I've recently have had interested in pursuing a Master in Counselling Psychology in Canada, but have come into a slight problem that I do not have good academic referee for me; and unfortunately, the public universities that I've contacted requires at least 1 academic reference.

I am just wondering if I've decided to opt for a Postgraduate Diploma or Certificate in Mental Health/Behavioral Science field, will that be a good idea and entry point to boost my possibility of eventually get into a Master program, in terms of both getting exposure of the field in Canada, and socializing for a reference as well?

For context, I'm a Malaysian Bachelor in Psychology (Hons) graduate, graduated 6 years ago.
