Mackenzie Financial Corp. said Friday it plans to merge several funds and change the management of its Keystone Altamira Fund line.

The changes would effectively merge seven Keystone funds into existing Mackenzie mutual funds currently managed by Mackenzie senior vice president Ian Ainsworth. Investors will be asked to approve the changes at a unitholder meeting.

Mackenzie’s proposals, outlined below, effectively terminate its sub-advisory relationship with Altamira Management Ltd., the advisor on the Keystone Altamira Funds.

The Keystone Altamira Funds, which were launched in December 2000, represent about $23 million in assets. The mergers are intended to occur on Oct.3, conditional on regulatory and investor approval.
