Contract A and Contract B
The terms Contract A and Contract B in Canadian contract law refer to a concept applied by the Canadian courts regarding the fair and equal treatment of bidders in a contract tendering process, for example to award a construction contract. Essentially this concept formalizes previously applied precedents and strengthens the protection afforded to those who submit bids in the tendering process.
