Google is facing more illegal heat this time from Canada.

Good morning. This is the Marketplace Morning Report and we're live from the BBC World Service.

I'm Leanna Byrne. Big Tech is back in the spotlight. Canada's competition watchdog has filed a lawsuit against Google, accusing it of unfairly dominating the online advertising market.

They're even asking Google to break up parts of its ad business.

It's a battle.

That's actually pretty similar to the antitrust fights in the US.

The BBC's Mariko Oi is looking at this one for us.

Hello.

Hello.

So what specific practices by Google triggered this investigation?

So this is specifically we're talking about online advertising.

And basically Canada's Competition Bureau has sued Google.

In a statement, the watchdog basically said that Google had allegedly illegally linked to advertising tools to maintain market supremacy and use its dominant position to distort

ad auctions by preferring its own tools. Now, Google has fought back saying that they will

fight this in court. It also said that the complaint out of Canada, and I'm quoting their statement,

ignores the intense competition

where ad buyers and sellers have plenty of choice, and they say we look forward to making

our case in court. So it's yet another legal battle that the US tech giant is facing, but

they're definitely fighting back this one as well. The Competition Bureau is asking Google to sell off

the major assets like Double Click

and AdEx.

How realistic is that those sales will happen?
