Initial opportunity (7)

I believe the answer is:

opening

I believe this clue is a double definition.

'initial' is the first definition.
(I've seen this before)

'opportunity' is the second definition.
(I know that opening is a type of opportunity)

(Other definitions for opening that I've seen before include "Opportunity, start" , "Opportunity; gap" , "Orifice; opportunity" , "Rent" , "Inauguration" .)

I've seen this clue in The Globe and Mail.
