The only issue I have ever had with LRTs, aside from terrible service times due to sharing the road with car traffic, is if anything goes wrong along the LRT, it's a full stop. This past winter, Dundas Street East LRT was out of commission for two weeks (if I recall) due to damage from that huge snow storm. Then there are fender benders in the same lane as the LRT, etc. Having an alternate route will be great.
Sounds a bit off topic but it's not. My point is...
I think people living along Dundas Street, Queen Street, King Street, especially where the OL intersects with King and Queen, it clearly would be faster and easier to just take the OL instead of streetcars. I would. Traffic is horrible during rush hour on Dundas, Queen, and King Street. All routes I take, frequently. Traffic can get so bad that I often literally beat the LRT by walking instead.
Using Canary Landing as an example, if I lived there, I would never take any of those streetcars again and just take the OL to the closest station and walk the rest of the way. It would be dramatically faster.
FYI: I'm not crapping on Streetcars either, just that they share the road with traffic instead of having a dedicated lane that only they use. I think they would be competitive with the OL if they were on a dedicated lane. Ah well.
