A few points from experience there:
The kollel has or had a list of gvirim but it may well be worth getting a driver if your friend is not familiar with Toronto (even with the percentage taken he is likely to be more successful).
There are a few families that regularly host meshulachim, I can only say words of praise for the edited family in specific.
The Va’ad itself generally has all the resources one may need (including numbers, addresses, hosting, etc). He should really be in touch with them to make all the necessary connections.
