In a non perfect Canadian world if there is no published departure - fly the missed approach profile of the runway departing ( departing 09 fly the miss of the approach to 09 ) or fly the approach of the opposite runway backwards.
Departing 09 fly the approach to 27 backwards.
Climb at best angle / rate until you get to sector alt.
Crude but it works.
If a/c performance doesn't allow this and a vfr departure not possible it is time to stop and think about it.
Always carry the Topo charts for the operational area.
Look at them before departure.
