To be exempt from these requirements, you must have studied full time in an English-language school system for the 4 most recent years preceding the beginning of your studies at the University of Waterloo.
The requirements are separate from, and in addition to, the requirement to present Ontario 4U English (or equivalent), if it is listed as a specific requirement for a program. A 4U English is required for most programs.
If you do not meet the requirements, you will be considered for entry into an English language pathway program.
You can improve your English before, or while, attending Waterloo.
See Waterloo's English Language Requirements.
