One way ticket to England, and then taking the train to visit other countries?

Your best bet is to buy a return flight ticket. The immigration people take a very dim view of individuals that arrive with only a one way ticket. - When do you plan to return, and how? Also, a return ticket is always cheaper than two one way tickets. You can buy an "open jaw" ticket to - from different cities for the same price as going to - from the same place. www.expedia.ca For two weeks in Europe, nothing beats the cost of a Eurail ticket. You chose which countries and which period you want to travel. That gives you total freedom to move around. There is very little need to pre-purchase the individual tickets but you MUST make sure that you have seats on the trains you want to go. Note - VERY IMPORTANT - you must purchase your Eurail tickets BEFORE you leave Canada.

As long as you can show the immigration officerf a return ticket to Canada, it doesn't matter if the return is from a different European country

I suggest you get return ticket Canada-London, and get your Europe tour ride from London then back. It's cheaper and more organised. I traveled to Brussels-Berlin-Amsterdam-Brussels before, booked one way but my ticket was return London-Brussels. Hope you get ideas from these sites below for your Europe trip...
