Well done.
I mentioned it there. I have an email into the city's electrical department requesting info on the service size from the street to the meter on the house. They should have an answer to me this week.

Well done.
MB, be sure to read the OP's original question. It was about finding a way to get power to his garage using some existing wiring and without upgrading his service. It was not about how to wire the garage panel.

Yes, I must apologize to Mr Johnstone, I kind of hijacked the thread.

This information is actually irrelevant. It's the service entrance size that matters.
The drop from the street is owned by the POCO and it's their call whether to replace it or not.

Can you clarify, when you say the drop you mean from the poles to the meter? The service entrance, is that from the meter into the house?

If the drop is not sized for 200 amps, doesn't it still pose some restrictions on whether I could have 100 amps in the house, and 100 in the garage?

Thanks,
Jim

Speedy refers to the wires that come from your meter up the service drop and out the head. At this point there is a connection to the utility, usually with compression connectors about 1-2' from the head itself. Very often these wires are sized for the main breaker, in your case 100 amp. These would have to be increased in size for a 200 amp system.

Is the power to house provided by your city or by an independent power company?

I'm pretty sure it's the city (Brantford Hydro, Brantford Ontario).
