U.S. Student Going To University Abroad For Undergraduate

Hello! I have some questions regarding going to university abroad for my undergraduate and maybe even graduate degree. I have some concerns mainly over tuition and room and board. I´m looking into two universities in Canada (University of Toronto and McGill University) and several universities in London (Kings College London, University College London, Imperial College, and Queen Mary University of London). On their websites they do have tuition posted for each different degree however there isn’t a posted room and board fee.
I was just wondering what the average room and board fee would be at some of the universities I listed above or just in general?
Also, suggestions for other good European universities that I could possibly consider would be great as well. Thanks!

I found the cost of residence for McGill in three clicks on their website:

In the UK you won’t generally find the all-inclusive room and board fees you get in the US. College accommodation is often only available for part of your time, and you may need to find private (usually shared) accommodation, whic will generally be pricier than college halls of residence. London will be much more expensive than other UK locations, so you might like to look a bit more widely.

In addition, you need to pay for food, and sometimes separately for utilities depending on the rental contract.

UCL suggests this as an average budget:
