Does University of Guelph give transfer credit for IB Computer Science HL?

This one comes with a significant caveat. CIS*9110 is a generic subject-area credit, not a specified exact equivalent. The "9" in the course number signals that Guelph recognizes the credit as belonging to Computing and Information Science but has not matched it to any specific CIS course in the catalogue. In practical terms, CIS*9110 counts toward your total credit count but will not be recognized as a prerequisite for any course. Whether it counts toward your degree's graduation requirements depends on your specific program; in some programs it may serve as an elective, in others it may not satisfy any particular requirement.

Official Award: IB Computer Science HL with a score of 5 or higher → CIS*9110 Generic CIS Credit (0.50 credits)

If you are entering a Bachelor of Computing or any program that requires CIS*1300 (Programming) or CIS*1500 (Introduction to Programming), you will still need to take those courses. CIS*9110 does not replace them and does not unlock second-year courses like CIS*2500 (Intermediate Programming) or CIS*2520 (Data Structures). For students in programs outside of Computer Science where CIS courses are not required, the value is more straightforward: it is a half-credit toward your total that you did not have to take a university course for.

If you believe your IB Computer Science HL work aligns closely with a specific Guelph CIS course, the university does allow students with generic credits to request a re-evaluation by the relevant department. In practice, because the university has already assessed IB Computer Science and assigned it a generic code in their published equivalency table, a different outcome is not guaranteed, but the process exists if you want to pursue it.

IB Computer Science SL does not earn any transfer credit at the University of Guelph. Only Higher Level courses with a final grade of 5 or above qualify, and the maximum across all IB HL subjects is 2.0 credits.

Since CIS*9110 is already a generic credit, the university's option to change specified transfer credit to unspecified credit within the first 30 days is less relevant here. That policy applies to students who received a specified equivalent (such as CHEM*1040 or ECON*1050) and want to convert it.
