Check kijiji.ca and try finding an apartment and contact the landlord and reserve it.
Since you're alone, 2 1/2 or 3 1/2 apartment is enough for you.
Once you land, take your copr and go to the nearest service Canada office and apply for social insurance number, you will be given the SIN right away and your card will delivered within 10 days.
Then take an appointment to take your driving license tests ( theory & driving )
Internet providers: Bell, videotron, distributel, acanac, bravo telecom ( check the prices online and chose what suits you best).
Cars 10 years old or older are tax free to register but you will have to pay the plate number every year arround 280$.
I hope this might help a bit, good luck.
