Your embassy might be able to tell you the exact requirements?

I spent 4 weeks in Togo and Benin in a 4x4 and never got asked once for my license - Togo wasn't the friendliest as it was a few days away from its first 'democratic election', but the cops in Benin were pretty good, inviting me to get a residents permit and live there.

On a scooter, I doubt it's much of an issue - I doubt most of the locals have a license to drive the bikes there? Else buy a local license ;-p

If asked, show your Canadian license with confidence, insist it is valid with a smile etc. If pushed just say its at the Canadian embassy being extended, you will have it next time, how is their family, is this the road to blah blah and smile a lot and be really nice.

Or - Photoshop is your friend in Africa - scan somebody else's, photoshop and print it out.... And print out something from Togo/Benin tourism office web sites and modify the text a little so it says your Canadian license is valid etc.

I had new ones sent out each year with my new Carnet.... best to get a few copies (there are two different formats by the way, some countries accept differing formats, but only an issue if you have a crash etc)

I only crossed at small borders which probably helps...

PS: Your probably supposed to have one in all of the other African countries you have been to so far including Ghana ;-)
