– “Leave to Construct” (Section 92) approval

– Recovery of project costs through transmission rates

• Provincial Policy Statement, 2005

• Design & construction according to industry standards and best practices

• Other municipal, provincial or conservation authority permits, as required

Existing transmission corridor• 115 kilovolt (kV)

transmission line built in the 1950s

• Easement rights, not ownership on this section of the right-of-way

• Right-of-way is 34 m (110’) wide along Deerpath Drive, with structures located 9 m (30’) east of centre

• Twin pole structures approx. 18-24 m (60’-80’) tall and spaced about 100 m (330’) apart

• Six twin pole structures between the railway and Hanlon Pkwy crossing; the latter is an angle structure

View along Deerpath Drive

Proposed transmission corridor• Upgrade transmission line to

230 kilovolt (kV) on existing corridor under existing easement

• Replace existing structures with steel poles, conventional or narrow base steel lattice towers, approx. 37-40 m (120’-130’) tall

• Spans between poles can be longer; e.g. three poles could replace five existing structures

• New structures adjacent to Deerpath Drive will be closer to the curb
