A sports-betting bill that sailed through the House of Commons is not getting a good reception from the Senate.

Conservative and Liberal senators  say they think they have the numbers to stop Bill C-290.

And if enough of them stand their ground, it would mark the first time the Upper Chamber has rejected legislation unanimously passed by members of Parliament.

If passed into law, each province would get to decide whether to allow single-game betting.

Currently, the provinces only allow multiple betting.
