The all-Canadian consortium that launched a hostile C$3.7 billion ($3.8 billion) takeover bid for TMX Group has no plans to sweeten its C$48-a-share offer or change any other terms, a source with knowledge of Maple's strategy said on Wednesday.

The source said, there was no intention right now of changing the terms for TMX, the operator of the Toronto Stock Exchange, TSX Venture Exchange and the Montreal Exchange for derivatives.

Maple Group Acquisition Corp, a group of 13 leading financial institutions, also aims to acquire Alpha Group, operator of Canada's biggest alternative trading system, and the CDS equities clearing hub, moves that are critical to the group's plan, the source said.

The group is confident the proposed acquisition of Alpha will win the Competition Bureau's approval, which Maple expects in September or October.

With less than two weeks before TMX shareholders vote on the London Stock Exchange's friendly $3.5 billion takeover, all sides were on the road in full force promoting their respective offers.

The heads of TMX and LSE, Thomas Kloet and Xavier Rolet, pitched their deal to Quebec business leaders in Montreal on Wednesday. Luc Bertrand, the public face of Maple, was in Calgary, Alberta, selling the group's bid to oil producers.

Meanwhile, a Reuters poll of TMX investors found that investors are warming up to Maple following the consortium's official bid, launched on Monday.
