BCSA through internal transfer

Bachelor of Computer Science and Arts (BCSA) Degree Program

“Over half of the students enter the programs as internal transfer candidates.”

It is known that the internal transfer to CS is almost impossible due to lack of capacity and stringent requirement.

How feasible to do BCSA trough internal transfer? Do they reserve some space and relax some requirements for students that major in arts?

Is the BCSA degree on par with BC in computer science?

Or just one way, students in CS to Arts, and do BCSA.
