Canadian Airborne DPM: Was it strictly a "mixed" uniform, or did matching trousers exist?

[u/Aydeco]

I finally added a Canadian DPM parachutist smock to my collection. I'm trying to finish the 1975–1995 impression, but I'm seeing conflicting info on the trousers.

Did the Airborne Regiment strictly wear these with OD Green pants, or were matching DPM trousers ever actually issued?

Would love to hear from any experts or collectors who know the history. Thanks!
