Informed by over two decades of a unique combination of senior level in-house, law firm and private business experience, Paul brings a unique perspective to his public and private sector clients. He combines strong analytical skills with practical business acumen to resolve challenging problems. Prior to joining Aird & Berlis, Paul worked at Metrolinx, where he managed the agency’s largest infrastructure projects, claims and contracts. As Senior Legal Counsel, he identified and managed risk; drafted and negotiated complex infrastructure, consulting and large product/service agreements; and structured and drafted the associated procurement models and documents.  On these projects, Paul developed strong skills in project management and organizing the input of stakeholders, including Project Managers, Technical and Engineering Consultants, and Utilities, Environmental, Finance and Procurement Advisors.

Paul has led negotiations with a wide range of sophisticated parties, including international infrastructure and construction companies and government representatives at the municipal, provincial and federal levels. He played a key role on 11 projects identified within Canada’s top 100 infrastructure projects, including Eglinton Crosstown Light Rail Transit, Finch West Light Rail Transit, Hurontario Light Rail Transit, Union Station Revitalization Project, Regional Express Rail Operator Procurement, Electrification, East Rail Maintenance Facility, Crosstown Tunnels (East and West) and the procurement, drafting and negotiation of vehicles (light rail vehicles for Eglinton, Finch and Hurontario LRTs, Diesel Multiple Units for Union Pearson Express, and heavy rail locomotives, bi-levels, boring machines and double decker buses).

Paul has negotiated a wide range of infrastructure, procurement, consulting and construction agreements, including Design-Build, Design-Bid-Build, Alternative Financing and Procurement, program management, consulting interface and the CCDC and CMGC variations of construction contracts. Paul has also advised on the development of new models for infrastructure delivery, such as Qualification-Based Selection, Alliance, Integrated Project Delivery, FIDIC and New Engineering Contract. 

Paul has provided claims and dispute support on all types of infrastructure contracts and related matters. He has attended mediations, arbitrations and dispute review boards on some of the largest construction claims in Canada and has supported judicial reviews and court actions, including at the Court of Appeal. As a result of this expertise, the Attorney General’s task force invited Paul to participate in committee meetings to revise the Construction Act.     

Paul has further experience advising various stakeholders in M&A, real estate, project finance and commercial transactions. Prior to his legal career, Paul completed an MBA and worked as a business consultant implementing project management, contract management, supply chain management, turn-around and cost savings strategies for businesses in various industries, including aerospace, hi-tech, manufacturing, food processing, hospitality and shipping.
