Canada Trust has decided on Boston-area agency Mullen Advertising to handle a special corporate advertising assignment expected to launch mid-1995.

Hill Holliday Connors Cosmopulos was also under consideration.

Media buying for its $7-million account is with Media Buying Services, Toronto.

Dianne Smith-Sanderson, vice-president of advertising and corporate communications, says Canada Trust plans to work with a number of creative agencies and review for each project.

The company’s relationship with Doner Schur Peppler, Toronto expires at the end of the year.
