Typically, all of us in the recruitment business (including our competitors) are not usually able to help articling students or new calls. It isn’t because we don’t care, but rather it is because our clients generally aren’t willing to engage our services in recruiting brand new lawyers. Most firms and companies will do their own advertising, usually on their websites and in the Ontario Reports, so your best bet is to check their websites & the ORs frequently and apply to them directly. You may also want to check with the career development officer at your law school, as some employers will post opportunities with the law schools.
