On Canada Post Delivery Time
 

If I have something shipped by Canada Post, at what time of day can I expect it to arrive?

It really isn't specific, in my experience. I've had a delivery note on my door at 8:30am once, and 4:30pm another time.
All i know is that sometimes, even though the delivery notice says 'tomorrow after x:xx', it shows up at your serving post office late evening the same day.

Depends on the method of shipping and the type of class.

Use this page to determine about how long it will take to arrive

Any time of day.

all depends on the person that is delivering it and the route they have.

Personally I know if I am waiting for a package it will come between 7:30am and 8am, anything after that time and its not coming

If your boss is okay with it, get them to send it to your work address.
That way you can be fairly sure that it won't go out on a route serving private addresses, and is *generally* more likely to show up around noon. Hopefully.
