About four months and I got one year from the date of approval. I would highly suggest you make a decision on whether to apply via the student pathway as soon as you can, because IRCC has raised the proof of funds requirement for a student from $10,000/person to $20,635 starting January 2024. That's just for living expenses and excludes tuition and travel.

Groceries are expensive here but we get by because I don't shop at the pricey stores. There are also lots of reduced prices everywhere--for produce, prepared foods, non-food items, etc.--and people take advantage of that to save money. I also walk to and from work, which saves me a ton that I would have otherwise used for transportation. My workplace is a manageable distance at 1.5 km away from my apartment. It's a good daily workout that helps me stay fit as I have a physically demanding job.
Looking to stay in this company for a year to gain full-time Canadian experience and then will apply again for positions in marketing and advertising. It's been difficult to get a job in my field after graduating. And it wasn't just me, but a lot of my other classmates as well. Be prepared for the highly competitive job market here. You might need to take a survival job for now like we have. It's not the best but it puts food on the table.
Sounds bleak; however, I don't mean to discourage you but to inform and arm you. Good luck to all!
