If travelling from, say, the CBD to Civic Hospital, consider two hypothetical bus systems:
System A: A 5-minute frequency bus down Bank, then at Catherine transfer to a 5-minute frequency bus down Catherine/Carling
System B: A direct single-seat ride on a 15 minute frequency bus
System A has an average wait of 2.5 minutes at your origin in the CBD; followed by an average wait of 2.5 minutes at the transfer point, for a total of 5 minutes of waiting.
System B has an average wait of 7.5 minutes at your origin in the CBD. So System A is actually 2.5 minutes faster despite requiring a transfer.
A high frequency grid of non-overlapping routes is the best form of transit.

What bus route has 5 minute frequency?
That kind of example is not likely to happen in Ottawa.
What is more likely to happen is that direct route actually will save you time because of the routing alone. In other words, the direct route is actually a straighter line from Point A to B than going through Point C.
You example also assumes that you are not going to look at a schedule before embarking on your trip.
I will give you another example. Route A is direct and runs every 30 minutes. Your average wait time is 15 minutes if you ignore the schedule.
By paying attention to the schedule, you may be able to reduce this to 5 minutes.
Route B runs every 5 minutes and takes you half way home. You wait 2.5 minutes. You have to transfer to Route C that takes you the rest of the way. Because it serves the same neighbourhood as Route A originally did, it still operates on a 30 minute frequency. Average wait time is 15 minutes. So, total wait time is 17.5 minutes. You can also pay attention to the schedule here too, but because of the transfer, you have allow yourself more time in case of delays.
No matter what, your trip (on average) is longer. The only way to make the transfer trip faster is run more buses than you do now.
This is a more likely scenario than the one presented.
