I am a student in Canada with a multiple entry visa. Am I able to do the following journey without the need for a transit visa?:
Istanbul - Munich - London - Toronto
The two European airports are:
London - Heathrow (LHR)
Munich - Franz Josef Strauss (MUC)
Please note the layover planned in both Munich and London is short.
London should be fine as you are travelling to Canada with a valid visa. See also Is there a way to find out if I need a transit visa for a layover in the UK?
Munich should be fine too. Turkish citizens do need a visa to transit there but there is an exemption for Canadian visa holders, see Do I need a visa to transit (or layover) in the Schengen area? for all the details.
