Good news indeed Brian!
However, I'm unsure about the "additional oral exam". Both unrestricted and restricted Certificates require an Oral exam. The difference is that the Oral for restricted is done aboard the vessel for which the Certificate is issued and is specific to that vessel, the Unrestricted Oral is more general and covers a greater scope. There's a huge Exemption given for qualifying service required for the Restricted CoC in subsection 2 (a) and (b) of MPR 151 so the "Restricted" really is "Restricted" to a specific vessel and is not valid on any other vessel which is not named on the Certificate.
From the Marine Personnel Regulations:
Small Vessel Machinery Operator
151. (1) An applicant for a Small Vessel Machinery Operator certificate shall meet the requirements set out in column 1 of the table to this subsection and the corresponding specifications set out in column 2.
Column 1 Column 2
Item Requirements Specifications
1. Experience Acquire at least two months of qualifying service as follows:
(a) at least 1 month of sea service as an engineer or a rating performing engine-room duties on one or more motor vessels; and
(b) any remaining time any combination of the types of service set out in item 2 of the table to subsection 147(1).
2. Certificates to be provided to the examiner
(a) MED with respect to small passenger vessel safety; and
(b) marine basic first aid.
3. Pass examinations
(a) Written examination on general engineering knowledge of small vessels, after meeting the requirements of items 1 and 2; and
(b) after passing the examination referred to in paragraph (a),
(i) oral examination on general engineering knowledge of small vessels if applying for an unrestricted certificate, and
(ii) practical examination on board the vessel in respect of which the certificate is sought if applying for the restricted certificate referred to in subsection (2). [/b]
(referring to table item 3 (b)(i), the "and" at the end of the line should be "or". If a candidate passes the oral exam in 3(b)(i), there would be no need for a Restricted CoC, he'd have an Unrestricted one. The "and" is just a typo. You can verify this with AMSPE In Ottawa)
(2) Despite item 1 of the table to subsection (1), an applicant for a Small Vessel Machinery Operator certificate restricted for use on board a specified passenger-carrying vessel that has a propulsive power of less than 750 kW and is engaged on a limited near coastal voyage, Class 2 or a sheltered waters voyage may, instead of meeting the requirements of that item,
(a) successfully complete training related to the propulsion system and safety systems fitted on the vessel; or
(b) acquire at least 10 days of sea service performing engine-room duties on the vessel or a vessel of the same class.
