Questions about schools in Canada

<p>So I am going to Canada for a year for my 10th grade and I have never been to a Canadian school.
Are there any major differences between American and Canadian schools?
Which one is harder?
Do they offer AP/Honors?
Would it be hard to transfer to a prep school in America if i go to Canada for a year?
Is there anything I should be worried about? </p>

<p>Thanks in advance ^.^</p>
