How much do the post office charge to exchange currencies?

[BigBugBites]

I want to change £500 into Canadian Dollars

Does anyone know what the charge is?

I can't find it online

Do you mean in branch or online ordering?

The website seems to suggest 0% commission

watch their rates though, .I had an appalling exchange rate from them last year.

Nowhere charges as such these days but all have different exchange rates. Post office is usually reasonable. Best is usually travelex though, you pay by card and it'll come by signed for post. However if you want to change cash (most debit cards inexplicably charge for foreign currency transactions) then suggest post office or
Marks and spencer.
