Re: I was told to purchase an Antennas direct DB4e antenna. Is this a good antenna for my location?

It's a fairly good antenna. There's a ton of them in Etobicoke. In your area, I can't be as sure but it may be fine.

Re: I figured a DB8e would've been better because I could aim it in different directions.

The DB8e is essentially two DB4e's horizontally ganged. Take a look at the tool on the Antennas Direct website that gives gain statistics for different orientation. You'll notice there's tradeoffs. It may be better for you than a DB4e, or maybe not, hard for me to pick one over the other without on the ground experience at your location.
