Cycling Network Gaps and Last-Mile Connectivity Challenges

A cycling lane that ends abruptly at an arterial intersection, or that connects two residential streets without reaching a transit station, is nearly as frustrating as having no infrastructure at all. Across Canada, network gaps — places where cycling infrastructure stops or deteriorates — remain a central obstacle to commuter cycling. This article examines where those gaps are most concentrated, why they persist, and what closing them requires.

Defining network gaps

A network gap is any segment where a cyclist travelling between two points must leave dedicated cycling infrastructure and merge with general traffic. Gap analysis in municipal planning documents typically classifies gaps by severity: missing links (no cycling facility of any kind), facility downgrades (where a protected lane transitions to a painted lane or sharrow), and terminus gaps (where infrastructure ends before reaching a destination such as a transit station, school, or employment node).

The City of Toronto's cycling network plan uses a gap analysis framework that scores candidate links based on directness, the severity of existing conflict (traffic volume and speed), and proximity to high-demand destinations. Similar frameworks exist in Calgary, Ottawa, and Montreal, though the specific scoring criteria differ.

Transit-adjacent gaps

The most consequential gaps, in terms of cycling uptake, are those immediately adjacent to transit stations. Research consistently shows that the final 800 metres — often described as the last mile — before a transit connection has an outsized influence on whether someone chooses to cycle to transit at all. A protected lane that terminates two blocks short of a subway entrance, with no safe crossing across a high-speed arterial, effectively breaks the trip chain.

Toronto's Eglinton Crosstown LRT opened a discussion about cycling access that illustrated this problem directly. Several planned station locations are located on arterials where no cycling infrastructure exists within 500 metres, and where the posted speed limit is 60 km/h. Without coordinated cycling infrastructure, the stations' walk-up catchment area becomes the practical limit of access for non-driving commuters without transit transfers.

Across 15 Canadian cities studied in the 2022 National Active Transportation Summit report, an average of 34% of transit stations had no cycling-friendly access route within 400 metres in any direction.

Jurisdictional barriers

Many of the most persistent network gaps occur at jurisdictional boundaries — where a municipal road ends and a provincial highway begins, or where two municipalities share a boundary. Responsibility for cycling infrastructure on provincial highways in urban areas is often ambiguous; provincial ministries of transportation generally do not build cycling infrastructure as part of standard highway management, while municipalities lack authority to modify provincial road rights-of-way.

The section of Highway 7 running through the Vaughan-Markham corridor north of Toronto is a documented example. It carries significant commuter traffic and is surrounded by residential and employment development, but because it is a provincial highway, the municipalities on either side cannot unilaterally build cycling infrastructure along it. Agreements between the province and municipalities are required, and these have been slow to materialise in corridors where provincial highway widening plans are also under discussion.

Inter-municipal coordination

Even where roads are entirely municipal, coordination between adjacent cities is complicated. Cycling infrastructure built to the boundary of one municipality may not continue in the adjacent jurisdiction, either because the neighbouring municipality has different design standards, different capital budget timelines, or different political appetite for lane conversions that remove on-street parking. The absence of regional cycling network authorities — bodies with funding power over cross-boundary routes — is frequently cited in planning literature as a structural cause of these gaps.

Neighbourhood-level dead ends

Beyond transit access, gaps within residential networks create dead-end cycling environments. In lower-density suburban areas, cycling routes on collector streets often terminate where a collector meets a high-speed arterial, with no safe crossing or continuation. Cyclists in these areas who want to continue must either use the sidewalk illegally, cross at a pedestrian signal with no cycling provision, or make a significant detour.

This pattern is particularly prevalent in cities built primarily after 1970, where the street network was designed around arterial-collector hierarchies without active transportation overlays. Edmonton's suburban cycling network faces this challenge extensively in communities built between 1980 and 2000, where the residential collector network has been retrofitted with painted lanes but the arterial crossings remain unresolved.

The last-kilometre problem at employment nodes

Cycling access to employment areas raises a different set of connectivity problems. Major office parks, industrial employment zones, and institutional campuses are frequently located on the interior of large blocks, accessible only from high-speed access roads that lack cycling infrastructure. The cyclist who successfully navigates an urban cycling network may find that the final 600 metres to their workplace requires merging onto a four-lane road with no shoulder.

The National Capital Region in Ottawa has documented this issue in its cycling master plan. Several large federal government employment nodes — including the Tunney's Pasture campus — are bounded by arterials where cycling infrastructure is incomplete or absent, creating a last-kilometre gap that affects thousands of potential cycling commuters daily.

Gap closure: what it costs and who pays

Closing network gaps varies enormously in cost depending on the type of gap. A missing painted lane on a low-volume street might cost $30,000 per kilometre. A missing link that requires a protected crossing of an arterial — with signal modifications, raised intersection geometry, and possible lane reallocations — can exceed $500,000 for a single intersection. Gaps on provincial highways require additional approval layers and are typically funded through cost-sharing agreements if they proceed at all.

Federal funding under Canada's Investing in Canada Infrastructure Program has flowed to active transportation infrastructure, but the criteria have favoured larger projects over the small-scale gap closures that would most directly improve network continuity. Municipal advocates have called for a dedicated gap-closure funding stream that can support smaller, high-priority links without requiring the administrative overhead of a major capital project application.
