Mr. Webster was a science teacher at Degrassi High School during the 1989-1991 school years. He had a noticeable Scottish brogue to his voice. Joey Jeremiah disliked Webster and often referred to him as "Webfoot."
Mr. Webster used the same science test repeatedly over several years, but after the answers were passed around to all of his students from one with an older sibling, he noticed the peculiarity and updated his test... at least for that bunch of students. He was portrayed by John Weir.
