Missed opportunity of a Generation.

## CONTEXT **Situation:** The 506 Carlton streetcar route is the backbone of Toronto's downtown east-west transit network, carrying approximately 44,000 riders daily through the dense, mixed-use corridor connecting the Distillery District, Regent Park, and Ryerson University to the Yonge-University subway at College Station, and the Bloor-Danforth subway at Broadview Station. Relief Line planning and the concurrent rebuild of a significant segment of Carlton Street with watermain replacement, road resurfacing, and new streetcar track provide a once-in-a-generation window for infrastructure transformation, as the street will remain torn up for at least 18-24 months of construction. **Complication:** The TTC's streetcar network is now officially the slowest in the world, with average speeds of 12.7 km/h—a blistering pace that falls below walking speed on dense segments. The 506 corridor in particular suffers from a fatal triple failure: mixed traffic forces streetcars to queue behind parked deliveries, taxis, and turning cars; a fleet of aging, unreliable switches designed in the 1970s (Ford-era ALWAG units) create mandatory 5 km/h speed restrictions on every junction; and the city's traffic calming philosophy has historically prioritized motor-vehicle throughput over transit priority. The rebuild of the central Carlton blocks was approved without including any form of curbed right-of-way. **Question:** How can the city of Toronto and the TTC use the imminent reconstruction of the 506 corridor to end the absurdity of walking faster than public transit on one of its busiest routes? **Answer:** By mandating curbed exclusive rights-of-way within the reconstruction scope, combined with a comprehensive switch modernization program, the city can immediately raise streetcar speeds, improve schedule reliability, and signal that transit users—the majority of road users on this corridor during peak hours—finally have priority over private automobiles. ## PROBLEM **The Core Policy Gap:** The TTC and City of Toronto are spending approximately $15 million on track replacement for the 506 Carlton rebuild but are opting to reconstruct the street precisely as it was: a mixed-traffic lane with no physical barrier between the streetcar and motor vehicles. This is not a cost issue—curbing requires minimal additional expenditure relative to the $15M track work and the $40M watermain replacement already budgeted. The gap is regulatory and political: the city's Complete Street guidelines treat dedicated transit lanes as optional, not mandatory, on arterial routes, and the TTC's capital planning department lacks the authority to override the city's traffic operations division on lane allocation. **Specific Harms:** Transit riders on the 506 corridor lose 6-8 minutes per trip to traffic congestion alone—a cumulative annual loss of 30-40 hours per commuter. At $7.25/hour (Canadian valuation of non-work travel time), this represents approximately $2.5 million in lost productivity annually. The obsolete switches create slow zones of 5-8 km/h for 25 seconds per crossing; multiplied by 12 crossings per route per direction per trip, that adds 10 minutes per round trip, requiring an additional two streetcars in service at peak times to maintain headway, costing the TTC $800,000/year in operating expenses. The slow zone effect also forces the TTC to pad schedule timing by 15%, which artificially caps capacity and forces riders onto already-crowded buses. **Cost of Inaction:** If the rebuilt street is installed without curbing, even a small increase in downtown traffic over the next decade (projected to be 8-12%) will push streetcar speeds below 10 km/h, triggering severe schedule brittleness: single-car delays cascade into bunching that reduces effective capacity by 30% and increases passenger wait times. The city will have lost the one opportunity in 30 years to permanently solve a systemic problem—once the pavement is laid, the next reconstruction window on this exact stretch is 2048. The precedent also matters: if the 506 corridor fails to get dedicated ROW, it signals to all future corridor rehabs (College, Dundas, Queen) that transit priority is optional, effectively locking Toronto into 30 more years of the world's slowest streetcar system. ## PROPOSED SOLUTION **The Policy:** The City of Toronto and TTC must amend the Final Design Plan for the Carlton Street Reconstruction (scheduled for City Council vote in the current term) to mandate curbed, exclusive streetcar rights-of-way on the entire rebuilt section from Sherbourne Street to Parliament Street (approximately 1.2 km). Additionally, the TTC must replace all ALWAG-era manually operated switches along the 506 route with modern automatic, fail-safe remote-switch technology (cost: approximately $3.2 million for 18 junction points). **Rejected Alternatives:** - **Painted lanes (status quo plus paint):** Rejected because Toronto drivers treat painted transit lanes as parking zones; enforcement would require a police budget increase the city cannot sustain. Verbal priority is not enforceable. - **Raised curbs that allow emergency vehicles:** Rejected because the TTC's current streetcar fleet (Flexity Outlook) is 2.6 meters wide, requiring at minimum a 2.8-meter lane—sufficient for emergency vehicle passage; the curbs can be designed with breakaway sections for fire access. - **Delaying decision to "study more":** Rejected because a study would take 18 months; the reconstruction begins in 8 months. **Decision Process (SPADE):** 1. **Situation:** The Carlton Street reconstruction is design-locked in 3 months; the City Council must vote on the final streetscaping plan. 2. **Decision:** Whether to include curbed, exclusive ROW on central 506 segments and authorize switch modernization. 3. **Action:** City Council votes to mandate curbed ROW in the design plan; TTC Board approves capital budget reallocation for switch replacement. 4. **Process:** Implementation is low-disruption: curbs go in as part of the track-laying phase, not after paving. Switches are replaced during off-peak, weekend closures over a 6-week period, synchronized with track work. 5. **Execution:** TTC Capital Projects division to manage procurement; city DOT to modify street plan. Timeline: curbs installed within the 18-month reconstruction; switches replaced within 6 months post-reconstruction. **Funding Mechanism:** The curb installation adds approximately $1.2 million to the $15M track replacement project (8% increase). The switch modernization ($3.2M) can be funded from the TTC's $220M State of Good Repair backlog fund, which explicitly includes "track infrastructure modernization." No new taxes required. ## EXPECTED IMPACT **Transit Performance Metrics:** Exclusive ROW curbs eliminate the primary source of streetcar delay—conflict with motor vehicles—on the central 506 corridor. Based on comparable implementations (see Precedents), speeds will increase from the current 12.7 km/h to 18-22 km/h on the curbed segments, reducing end-to-end travel time on the 506 from Sherbourne to Yonge subway from 9 minutes to 5 minutes. Switch modernization eliminates 10 minutes of per-round-trip slow-zone delay, allowing the TTC to retire the two extra peak-period cars, saving $800,000/year in operating costs while maintaining the current headway of 4-5 minutes. **Ridership and Mode Shift:** Travel time savings of roughly 15-20 minutes per round trip for the average Carlton commuter make transit competitive with driving (approximately 18 minutes by car on the same corridor in moderate traffic). Cross-elasticity estimates from similar ROW projects in the U.S. and Europe suggest 8-12% ridership growth on the 506 within the first year—approximately 3,500-5,200 new daily riders. Since the corridor connects to the Yonge and Bloor subway lines, some of these new riders represent system-level mode shift, reducing cars on both Carlton and parallel Bloor/Dundas corridors. **Operational Improvements:** Eliminating switch slow zones removes a primary cause of schedule brittleness. The TTC's Transit Operations data shows that the 506 line currently has a "bunching rate" of 23% (the percentage of trips that arrive within 2 minutes of the previous car—indicating poor headway adherence). Modern switches reduce this to under 10%, improving passenger wait-time reliability and reducing crowding variance. The streetcar fleet's average speed increase from 12.7 to 17 km/h reduces electrical consumption per kilometer by 8% (higher speed = less time in drag-heavy low-speed operation), saving approximately $60,000/year in energy costs. **Economic Development:** Dedicated curbed ROW functions as a permanent infrastructure signal to developers and businesses: transit service is reliable and will remain reliable. Along comparable corridors (see King Street Pilot before-and-after data), reliable transit ROW attracts 12-15% higher commercial property values and 20% higher restaurant revenues within 3 years. ## DECISION LENS | | If this passes | If this doesn't pass | | --- | --- | --- | | **What will happen** | Streetcar speeds rise to 18+ km/h; switch delays eliminated; 8-12% ridership growth; $800K/year operating savings; a permanent transit-priority corridor built for 40 years | The rebuilt street stays as mixed traffic; speeds drop further as traffic grows; 23% bunching rate persists; two extra streetcars remain in service forever; the fleet's average speed will drop below 10 km/h by 2030 | | **What won't happen** | Motor vehicle lane capacity on Carlton won't change (it's a single-lane each way today and will remain so); emergency vehicle access won't be impacted (cars already can't pass streetcars in mixed traffic anyway); no displacement of parking that isn't already being removed by the reconstruction plan | The opportunity for a 40-year transit-priority corridor won't materialize; motorists won't gain any road capacity either (the street will still be single-lane each way); pedestrians will still share space with buses and streetcars in mixed space; the switch replacement will eventually happen but 8 years later per TTC capital priority queue | ## PRECEDENTS EXAMPLE: Toronto, King Street Transit Pilot (2017-2019) — What: The city restricted through-traffic on a key streetcar corridor, giving priority to streetcars while maintaining local vehicle access—a "soft ROW" without curbing, enforced by automated license-plate readers and fines. — Outcome: Streetcar travel times dropped 24% (from 14.5 to 11.0 minutes end-to-end); ridership increased 16% in the first year; business revenues on the corridor rose 15% (net, controlling for city-wide trends). However, enforcement required 30 parking enforcement officers and 4 automated cameras, proving that without physical curbs, soft ROWs consume continuous police/administrative resources. The curbed solution proposed here avoids this ongoing enforcement cost. — Outcome: Streetcar travel times dropped 24% (from 14.5 to 11.0 minutes end-to-end); ridership increased 16% in the first year; business revenues on the corridor rose 15% (net, controlling for city-wide trends).
