Noise & Vibration (Lakeshore West Corridor)

• When new infrastructure is built, Metrolinx undertakes a

Noise and Vibration Modelling study to determine baseline

conditions as well as assess potential impacts once the

infrastructure has been built. Based on the results of the

study for the Lakeshore West Corridor, no noise mitigation

was recommended.

• Noise related to existing and future service is a concern that

we have heard across the region, so we are committed to

looking at any changes that can be made to reduce noise for

our neighbours.

Lakeshore West Corridor–Electrification Infrastructure

• Approximately 49 km of electrified corridor

• Two Hydro One Tap Locations:

o Burlington Tap

o Mimico Tap

• Traction Power Substations

o Burlington TPS

o Mimico TPS

o 25 kV Feeder Route

• Two Switching Stations

o Oakville SWS

o Mimico SWS

Lakeshore West Corridor–Bridge Modifications

• Along Lakeshore West Corridor there is a total of:

• 9 road bridges over rail; and,

• 2 pedestrian bridges over rail

• Bridges over the rail corridor will require bridge barriers for safety.

• Sunnyside Pedestrian Bridge and Drury Lane Pedestrian Bridge will require barriers. The addition of the barriers could make the bridge structurally unsound. Therefore these bridges will need to be structurally reinforced or replaced.

• In order for trains and the electrification wires to meet the clearance requirements under Strachan Avenue, Brown’s Line, Royal Windsor Drive, Dufferin Street, Dowling Avenue, Dunn Avenue, Jameson Avenue and Drury Lane Pedestrian Bridges, an engineering solution is required to increase the distance between the top of track and bottom of the bridge.

Drury Lane Pedestrian Bridge Sunnyside Pedestrian Bridge

• Cultural Heritage Evaluation Reports are being completed for several

bridges to identify heritage value. Bridges identified as heritage will have

Heritage Impact Assessments completed to protect heritage features.

Mimico Tap/TPS/25 kV Feeder Route

• The Mimico Tap/TPS is to be

located on a parcel of land

situated on property at the

south west corner of the Canpa

rail corridor and Milton corridor,

west of Kipling Avenue.

• The 2x25 kV Mimico feeder

route will commence at the

Mimico Tap/TPS location and

run south via aerial cables

along the Canpa Rail right-of-

way to the Mimico SWS site.

The aerial feeder will be

supported by poles similar to

typical hydro poles.

• The Canpa rail right-of-way is

owned by Metrolinx.

• The Mimico Tap/TPS site is

currently mainly open

space/vacant lot with a building

and parking lots/storage areas

and a rail corridor to the north.

• The Mimico Tap/TPS site is

currently owned by Hydro One.

Mimico Switching Station

36 Towns Road Toronto, west of the GO Transit Willowbrook Rail Maintenance Facility, north of

rail corridor

• The Mimico SWS is to be located on a

parcel of land at 36 Towns Road in

Toronto, just west of the GO Transit

Willowbrook Rail Maintenance Facility

and north of the rail corridor.

• Towns Road is an industrial cul de sac,

and the parcel is surrounded by industrial

development. The parcel is currently

being used as an industrial storage area,

with some vegetation cover adjacent to

the rail corridor.

• The proposed positioning of the SWS

within this parcel is adjacent to the rail

corridor and is currently storage area and

vegetation.

• The property is currently privately owned.

Current conditions at the proposed Mimico

Switching Station site.

Oakville Switching Station

560 Maple Grove Drive Oakville, southeast of the rail corridor

Current conditions at the proposed Oakville

Switching Station site.

• The Oakville SWS is to be located

on a parcel of land at 560 Maple

Grove Drive in Oakville. The site is

southeast of the rail corridor and is

currently an intermodal facility

(parking/storage area), with a

shopping plaza and office

buildings to the south.

• The proposed positioning of the

SWS is at the northwest side of

the parcel adjacent to the rail

corridor.

• The property is owned by

Metrolinx.

Burlington Tap/Traction Power Substation

845 Laurentian Drive Burlington north of the rail corridor, southwest of Cumberland Avenue

Current conditions at the proposed Burlington

Tap and Traction Power Substation site.

• The Burlington Tap/TPS is to be located on

a parcel of land situated east of 845

Laurentian Drive in Burlington, and

includes the existing Hydro One

Cumberland Transformer Station (TS). The

site is accessed via Cumberland Avenue.

• The parcel is currently a parking lot, short

driveway, the Cumberland TS with

associated transmission lines, and some

open space/vegetation. It is located

between a building supply operation to the

east and a manufacturer of transformers to

the west.

• The proposed positioning of the Tap/TPS is

at the southwest corner of the parcel,

adjacent to an industrial building, and is

currently open space/vegetation.

• The Tap/TPS property is owned by Hydro

One.
