You had also applied for a two-year diploma program? Because the update from today basically says:
As of 8:30 a.m. ET on January 22, 2024, most new post-secondary international students at the college or undergraduate level must provide a provincial attestation letter (PAL) from a province or territory with their study permit application. Immigration, Refugees and Citizenship Canada (IRCC) will return any application received that does not include a PAL, unless otherwise exempt.
...
International students whose applications were received by IRCC before 8:30 a.m. on January 22, 2024, as well as those who have already been approved for a study permit and intend to travel to Canada for an upcoming program, do not need to take further action as a result of the cap."
I don't think yours would get stuck, but unless you're from the exempt list, you'll be refused.
