Yes, it is possible to seek admission and apply for a visa without IELTS or English requirement. (Ref. Gov. Canada Directions Concerning ESL, FSL Courses)
However, it is important to note that English language assessment is very important in getting admission to study, and in meeting visa requirements.
This is how you may still qualify for admission to a full-time educational program and apply for a visa even if you don’t have IELTS or English Assessment predetermined:
Option One:
You are a citizen or have completed your current education from one of the countries in this list:
Then you are not required to have an English language assessment.
Option Two:
Conditional letters of acceptance (LOA). You may apply for conditional acceptance as follows:
“When successful completion of a prerequisite course or program is required before admission into a program of study, the DLI may issue a conditional letter of acceptance to a foreign national. This letter should be submitted when the applicant applies to enter Canada as a temporary resident.
“When the completion of a prerequisite program, such as English as a second language (ESL) or French as a second language (FSL), is a condition for enrolment in a subsequent program, officers issue a study permit for the length of the prerequisite program plus 1 year.”
Note: Foreign nationals who have been issued a study permit for a prerequisite program are not eligible to work off-campus in Canada until they begin their main program of study.
