That won’t work either. Pretty sure Pakistani nationals require a transit visa for the UK as well. It highly unlikely that the OP will be able to get on a plane in Dubai to go to the UK, never mind Canada.
So TRV if not approve then? or Transit visa not approve then? because too much fed up.
Because if they will say me that your destination is CUBA go there or go back to your country?
But now if i alive then can come there or get asylum other wise thanks.
Do I need a visa if I’m just travelling through Canada on my way to another country?
Most people who travel through Canada need a visitor visa, a transit visa, or an Electronic Travel Authorization (eTA).
