Standing Order 116 clearly speaks to this issue. It says:
In a standing, special or legislative committee, the Standing Orders shall apply so far as may be applicable, except the standing orders as to the election of a Speaker, seconding of motions, limiting the number of times of speaking and the length of speeches.
End of debate.
(2)(a) Unless a time limit has been adopted by the committee or by the House, the Chair of a standing, special or legislative committee may not bring a debate to an end while there are members present who still wish to participate. A decision of the Chair in this regard may not be subject to an appeal to the committee.
(b) A violation of paragraph (a) of this section may be brought to the attention of the Speaker by any member and the Speaker shall have the power to rule on the matter. If, in the opinion of the Speaker, such violation has occurred, the Speaker may order that all subsequent proceedings in relation to the said violation be nullified.
Not only does it not speak to a limit of time for the member to speak, it specifically says that, once I move the motion, until I'm done and then until everyone who has indicated that they subsequently want to speak are done, the matter is the one that the committee is seized with.
