I love Blizzard, namely Frank & Bob and Kimia who seem to run this place. I work as the Receptionist for business that heavily uses Blizzard for our local & GTA courier needs and I couldn't be happier as I'm the first person contact for anything courier related. Bob and Frank are communicative, accommodating and sweet as pie. They are quick to fix problems and are amazing at following up when clients are not home to sign for packages.
They also have a very user friendly online courier request service (done through a web url through your internetz).
Things to watch out for:
If you send 2 different packages to the same address under 2 separate courier requests, their billing service will charge you twice.
The online courier request service has the option to get a signature from the recipient, OR "leave in mailbox" - Blizzard calls every single time to notify me when a client is not home and ALWAYS waits for clearance to leave packages unattended when I check mark "signature required"
In general, great courier company for mid-big sized businesses! Happy to have been working with them through my firm for 4 years
