There is a procedure for those that cannot find a guarantor. BUT: it will require extra work and issues and possibly delays.
If you can find a guarantor in Vancouver, that would be better - use the post. Again, it really only needs to be an adult who holds a valid Canadian passport and has known you for two years.
Here's the procedure if you literally cannot find a guarantor:

Note, a notary in this procedure is not 'acting as a guarantor' - they're just having you swear an oath before them; any notary should be willing to have you swear such an oath. (Not an expert, I think this is an accurate summary.)
