how long does it take to get train from london to runcorn
The train from Gatwick Airport to East Croydon Station would take about 20 minutes.
By train, take any northbound train from the station (don't take from the Gatwick Express, or any train destined for Reading) and get off at East Croydon.
Coulsdon is at the southern edge of London. I doubt if you could get a cab to go from central London all the way to Coulsdon. To go by road from say central London to Coulsdon could take 90 min to a couple of hours in the day
Best bet is to get into London Victoria from East Croydon, take the Victoria Line to Oxford Circus, the Central Line to Liverpool Street, and then the Stanstead Express from Liverpool Street.
Around 1 1/2 hours
Presumably you mean London, Ontario.

You can't take a train directly from the Shetland Islands to London. You can't even fly directly between Shetland and London. You could travel by boat from Shetland to Aberdeen and then take a train or fly from there to London or you could fly from Shetland to Edinburgh and either fly or take a train from Edinburgh to London.
30 minutes if there are no issues in the London station
