This question is marked on the quality of the reasoning rather than on the choice of issues, and the instruction that carries the marks is “for and against.” The candidate is being tested on whether they can argue the side they disagree with well enough that a reader could not tell which side that is. The two issues below are live in most Canadian communities of any size, and each is set out with its context, the case for, the case against, and a planner’s resolution.

Issue 1 — Permitting secondary suites and small multiplexes as of right in established single-detached neighbourhoods. The municipality is considering amending the Zoning By-law so that a secondary suite, a garden suite, and a duplex, triplex or fourplex would be permitted as of right on any lot presently zoned for a single detached dwelling, subject only to the existing height, setback and coverage regulations — removing the rezoning, and therefore the public hearing, from each individual proposal.

The case for. It adds housing supply where the servicing, roads, transit, schools and parks already exist, at a fraction of the municipal capital cost of the equivalent greenfield subdivision, and it does so without extending the urban boundary onto farmland. It is the form of density that is least visually disruptive, because a fourplex can be built to the same height and footprint as a large single-detached house. It broadens the range of housing available in neighbourhoods that currently offer only one product, which serves the aging resident who wants to remain in the neighbourhood in a smaller unit, the young family priced out of it, and the household that needs a rental unit’s income to afford the mortgage; measured against the conventional affordability threshold of 30 per cent of before-tax household income, these are the units that most nearly reach it without subsidy. And the as-of-right mechanism matters as much as the permission: a project that requires a rezoning and a public hearing for every small building is exposed to a process cost and a delay risk that only large developers can carry, which is precisely why gentle density stopped being built.

The case against. Existing owners bought into a settled regulatory expectation and are entitled to say that a unilateral change to it is unfair. The local effects are real and are borne unevenly: on-street parking pressure where the additional units come without additional spaces, shadow and overlook onto immediate neighbours, tree canopy and permeable surface lost to additional building footprint and driveway, construction disruption, and sanitary and storm laterals in older areas that may be at or beyond capacity even though the mains exist. Removing the site-by-site hearing removes the neighbours’ only formal voice, which is a genuine democratic objection and not merely an inconvenience. There is also a fair question about whether the units produced will be affordable in fact: infill in a desirable neighbourhood may deliver expensive units and, in some cases, replace older lower-cost rental buildings with new ones at higher rents.

Resolution. The planner’s answer is not to choose a side but to separate the two arguments that are being conflated. The objections to effects — parking, servicing, shadow, trees, drainage — are legitimate and are answerable with regulation: unit-count and floor-area limits scaled to lot size, coverage and permeability standards, tree retention requirements, a servicing capacity review by area rather than by application, and reduced parking requirements only where frequent transit genuinely exists. The objection to process is answerable by being explicit that the trade-off is deliberate: the hearing is moved from the individual building, where it decides nothing of principle at great cost, to the bylaw amendment itself, where the principle is actually decided and where everyone in the municipality — including those who do not yet live there — has a stake.

Issue 2 — Reallocating a general traffic lane on a busy arterial to a protected bicycle lane and transit priority. The municipality proposes to convert one of two travel lanes in each direction on a four-lane urban arterial into a separated cycle track on one side and a bus priority lane on the other, retaining turn lanes at the signalized intersections.

The case for. The corridor already carries near its capacity in vehicles and cannot be widened without demolition, so the only remaining way to increase the number of people it moves is to change what occupies the space: a general traffic lane moves roughly 1 900 vehicles an hour at about 1.2 persons each, while the same width run as transit priority or as a protected cycle track moves substantially more people. A protected facility is what converts latent cycling demand into actual trips, because the barrier to cycling on an arterial is perceived safety rather than distance. Collision severity falls when lanes are separated and crossing distances are shortened, which matters most for the pedestrians who are currently crossing four lanes. Transit reliability improves immediately, and a reliable bus is the cheapest ridership investment available. The corridor also serves the municipality’s own adopted plan objectives on mode share and emissions, which cannot be met while every arterial is allocated entirely to one mode.

The case against. Removing a lane on a corridor already at capacity will, at least initially, increase delay and divert traffic onto parallel residential streets, which imposes the cost on a different set of residents who were not part of the decision. Businesses fronting the corridor depend on the passing traffic and on the curbside parking and loading that the reallocation typically consumes, and their concern about access is concrete and immediate while the cycling benefit is prospective. Emergency response times on the corridor may be affected. Goods movement is a legitimate competing claim if the arterial is a designated truck route. And in a cold climate the utilization of a cycle track is seasonal unless the municipality funds winter clearing, so the comparison of persons moved must be made honestly across the year rather than in July.

Resolution. The disagreement is largely about evidence and sequence rather than about values, so the planner’s contribution is to structure both. Model and monitor the diversion, and pair the reallocation with traffic calming on the parallel residential streets so that the diversion does not simply move the problem. Redesign the curb rather than deleting it, providing loading zones and short-stay parking in the places the businesses actually need them, and commit to a before-and-after count of business activity rather than arguing about predictions. Commit to the winter maintenance standard in the same decision that builds the facility. And implement as a monitored pilot with published criteria and a defined review date, which converts an argument about what will happen into an agreement about how it will be measured.
