Professional Background

Mollie Deyong is an Associate in the Construction and Infrastructure Practice Group at Singleton Urquhart Reynolds Vogel LLP. Mollie has a steadfast interest in infrastructure projects and has specialized in construction and infrastructure since the outset of her legal career.

She has honed her skills in respect of drafting and negotiating standard form and bespoke contracts of varying degrees of complexity, including design-build contracts, construction (design-bid-build) contracts, construction management contracts, supply contracts, and professional services contracts. She understands the importance of both high level risk considerations and technical details, and has facility with all manner of contract documents including technical specifications, commercial contract schedules, contractual amendments and change documentation.

In addition to providing front-end services, Mollie works with clients both large and small representing their interests in respect of a myriad of construction-related issues. She is a construction industry lawyer with experience in large-scale infrastructure disputes, negotiation, mediation, multi-party litigation, arbitration, procurement matters and resolving legal issues that arise on construction projects in both Ontario and British Columbia. She has experience working with large infrastructure owners, mid-size project owners and developers, contractors, suppliers, consultants and design professionals.

As her practice includes both front-end transactional work and dispute resolution for construction industry clients, Mollie is uniquely positioned to assess her clients’ needs, craft legal solutions that avoid costly disputes, and deliver cradle-to-grave construction project advice with a focus on service excellence.
