Hi Sabit,
Getting into law school in the UK is relatively easy and there are no entrance exams.
I have outlined below the most usual route to becoming a solicitor (as opposed to becoming a barrister or legal executive or other less usual routes - http://www.allaboutlaw.co.uk/index.php/types-of-lawyer/).
The usual process is to complete an undergraduate degree and the go to law school (one year if your undergraduate degree was an LLB, or law degree and two years if you did another subject.)
Then in addition to completing law school (Scotland and Northern Ireland have their own systems) you will need to complete a two year training contract (I think they call it articling in Canada).
The course you need to take at law school is called the Legal Practice Course or LPC http://www.allaboutlaw.co.uk/index.php/courses/lpc/ which takes one academic year to complete.
In order to be eligible for the LPC you need to have an LLB (law degree) or have successfully completed the GDL which is the law conversion course. http://www.allaboutlaw.co.uk/index.php/courses/gdl/
If you finish your law degree in Canada you might (you will have to check with individual schools) be able to skip the GDL - possibly not - it would depend on how much overlap there was between modules I suppose.
The problem with coming to the UK is that once you complete law school you need to get a training contract and there are not enough to go around. Many you have to apply for two years before you want to start. So you have to consider that you might come to the UK, finish law school and not be able to find a job.
So overall getting into law school isn’t difficult. Here are rough costs of the different courses http://www.allaboutlaw.co.uk/index.php/courses/law-school-fees/
If you speak to any of the law schools they will be able to help explain their entrance requirements and what might be the best possible route for you.
I hope that helps,
Jack
