The majority of the drafting offices surveyed are attached to the Department of Justice or the Ministry of the Attorney General, as the case may be. [...] At the federal level, there are three drafting offices : the Legislative Services Branch of the Department of Justice — which includes the Drafting Services Group, the Bijuralism and Drafting Support Services Group, the Advisory and Development Services Group, and the Publishing Services Group — ; the Office of the Law Clerk and Parliamentary Counsel of the Senate ; and the Legislative Counsel Off [...] As a result, while the initial version of a bill is prepared by drafters in the Headquarters Legislation Section or the Finance Tax Drafting Services Section of the Department of Justice's Legislative Services Branch, subsequent versions are drafted by the Office of the Law Clerk and Parliamentary Counsel of the Senate or by the Legislative Counsel Office of the House of Commons. [...] In Ottawa, private members' bills to be introduced in the Senate and motions to amend such bills are drafted by the Office of the Law Clerk and Parliamentary Counsel of the Senate, while private members' bills to be introduced in the House of Commons and motions to amend such bills are drafted in the Legislative Counsel Office of the House of Commons. [...] In addition to providing formal training on legislative drafting to officials of the Department of Justice and, occasionally, to provincial or territorial officials, the Group gives advice on the legislative and regulatory processes, the choice of legislative instruments, the interpretation of legislation and the legal framework of regulation making.
