The merger between a growing American exchange-traded funds giant and a huge international mutual funds manager apparently is about to bring a global twist to the evolution of the PowerShares family.

London-based Invesco has announced this week a rebranding in Canada to integrate its purchase of Trimark Financial and existing product lines. That has analysts speculating about a possible move to offer Invesco PowerShares ETFs on the Toronto Stock Exchange. 

The Globe and Mail newspaper talked to an Invesco Trimark official, who wouldn't confirm that PowerShares ETFs might be listed on the exchange, possibly sometime this fall. 

But Peter Intraligi did tell reporter Shirley Won: "Because we talk about bringing the best of Invesco to our clients, we will look at things like launching PowerShares and look at all of our investment capabilities around the globe."

Won also reported that the company has been "testing the waters" since June by including some PowerShares ETFs with new retirement portfolios in Canada.

That is no doubt bound to fuel more rumors of PowerShares' expansion plans across the globe ... stay tuned. (Invesco bought PowerShares in 2006).
