What is the maximum backlog limit for applying in Canadian universities?

There is no official consent over the number of backlogs. But, you should have least number of backlogs. Many colleges give admission with 7-8 backlogs but remember those students fail to get visas. Visa officers do not grant visa to students with more than one or two backlogs.

The quantity of backlogs is not the subject of a formal agreement or rule. However, you should have the fewest possible backlogs. Many institutions admit students who have 5-8 backlogs, but those students often struggle to obtain visas. Students having more than one or two backlogs are not permitted
