Calgary to London is about eight and a half to nine hours in the air with seven hours of difference. It is an energy route, and it behaves like one: weekday business travel, early starts and very little slack.
Seven hours, worked from home
Late morning in Calgary is early evening in London. You can settle the whole thing the day before without being awake at an odd hour at either end.
Winter and the thaw
Calgary winters freeze, thaw and freeze again, and de-icing delays are routine between November and March. A late departure turns a morning arrival into the afternoon, so keep the first day loose.
Differences from home
The legal position in the United Kingdom is not the same as in Canada, and the differences are not intuitive. It is worth understanding properly rather than assuming. Tipping is also not expected on top of an agreed fee.
The flight home
Going home takes longer than coming over. Heading west you are flying into the jet stream rather than along it, and on this route that is worth roughly an extra hour in the air. London back to Calgary is scheduled accordingly, so read the arrival time rather than assuming it mirrors the flight out. It matters most if you have a connection waiting at the other end.
Before you book
Visitors from Canada who do not need a visa still need an electronic travel authorisation, or ETA, before they fly. It is a short online application, and it should be made through the official GOV.UK ETA service, not a site that charges extra to do it for you. The rules change, so check them before you book.
Worth reading first
The visitor guide and the UK law guide cover both properly.

Areas near where you land at Heathrow
The big figure is the straight line distance from the airport in miles, and nothing about travel time, which in London is always longer. Each page has the stations, the route from Heathrow and the measured rates.
Also close to where you land, with no profiles of their own but a guide to getting there and how outcall works: Feltham, Hayes, Hounslow, Southall.

Common questions
How long is the flight from Calgary to London?
The flight from Calgary International takes about 8.5 to 9 hours eastbound. Add the connection time if your fare has a stop, and allow for getting to and through the airport at both ends.
What is the time difference between Calgary and London?
London is 7 hours ahead. The United Kingdom and most other countries change their clocks on different dates, so for a few weeks each spring and autumn the gap shifts by an hour.
What time should I message from Calgary?
London runs 7 hours ahead of you. Messages sent between about 4am and 4pm your time land during London working hours, which is when replies actually come.
Which London airport do flights from Calgary land at?
Most land at Heathrow, about fifteen miles west of central London and on the Piccadilly line and the Elizabeth line. Some services use Gatwick, to the south, so check the airport on your ticket before you book a hotel.
Do I need an ETA to fly from Calgary to London?
Most visitors from Canada who do not need a visa need an electronic travel authorisation, or ETA, before they fly. Apply through the official GOV.UK service only, and check the current rules before you book, because they change.
Do I need to arrange things before I fly?
It helps. Good diaries fill days ahead, and arranging from home means you are doing it awake and unhurried instead of jet lagged in an unfamiliar city.
Is escorting legal in the UK?
Yes, in England and Wales it is legal for two consenting adults to exchange sex or company for money. What is illegal is the activity around it, such as soliciting in the street, running a brothel or controlling someone else's work. The Crown Prosecution Service sets this out in its published guidance.
Is prostitution legal in the UK?
Selling and buying sex between consenting adults is not itself a crime in England, Wales or Scotland. Northern Ireland is the exception, where paying for sex has been an offence since 1 June 2015. Public soliciting, brothel keeping and exploiting another person's work are offences in different forms across the UK.
