Once again, we are talking about Ottawa's light rail system, as the service's long-term concerns are nagging within the big brain of Beacon Hill-Cyrville councillor Tim Tierney.

He says there are a combination of issues plaguing OC Transpo, and we highlighted some of them in the previous hour as well.

Plus, CFRA's Chris Holski addresses a handful of logistical issues with the 'bubble bylaw' proposal.
