ARTICLE 10
INDEMNIFICATION

10.1 ATS covenants and agrees to protect, indemnify and hold harmless each of the Standby Purchasers for and on behalf of itself and for and on behalf of and in trust for each of its directors, officers, employees, agents and shareholders from and against any and all losses, claims, damages, liabilities, costs or expenses caused or incurred:

(a)

by reason of or in any way arising, directly or indirectly, out of any Misrepresentation or alleged Misrepresentation in the Prospectus;

by reason of or in any way arising, directly or indirectly, out of any order made or inquiry, investigation or proceeding commenced or threatened by any Securities Commission, or other competent authority in Canada or the United States or before or by any Governmental Entity, based upon or relating to any Misrepresentation or alleged Misrepresentation in the Prospectus, or any other document filed with the Securities Commissions in connection with the Rights Offering or the Prospectus, or relating to the Rights Offering or other transactions contemplated in this Agreement including, without limitation, any actions taken or statements made by or on behalf of ATS in connection with the Rights Offering or the other transactions contemplated in this Agreement (excluding, for greater certainty, any statements made by or on behalf of ATS exclusively to one or more Indemnified Parties);

-29-

(c)	the non-compliance or alleged non-compliance by ATS with any requirement of the Securities Laws or any other applicable Laws in connection with the Rights Offering or the other transactions contemplated in this Agreement, including ATS’ non-compliance with any statutory requirement to make any document available for inspection;
(d)	by reason of, or in any way arising, directly or indirectly, out of any breach or default of or under any representation, warranty, covenant or agreement of ATS contained herein.

10.2	Each of the Standby Purchasers severally and not jointly covenants and agrees to protect, indemnify and hold harmless ATS for and on behalf of itself and for and on behalf of and in trust for each of its directors, officers, employees and agents from and against any and all losses, claims, damages, liabilities, costs or expenses caused or incurred by reason of, or in any way arising, directly or indirectly, out of any breach or default of or under any representation, warranty, covenant or agreement of the Standby Purchaser contained herein.

(b)	the named parties to any such claim, action, suit or proceeding (including any added, third or impleaded parties) include both the Indemnifying Party and the Indemnified Party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them (such as the availability of different defenses).

-30-

10.6

Subject to Section 10.5, it is understood and agreed that the Indemnifying Party shall not, in connection with any claim, action, suit or proceeding referred to in Section 10.5 commenced in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate legal firm for all Persons in respect of which indemnification is or might reasonably be considered to be provided for herein and such firm shall be designated in writing by the Indemnified Party (on behalf of itself and its directors, officers, employees and agents).

10.7

Notwithstanding anything herein contained, no Indemnified Party shall agree to any settlement of any claim, action, suit, proceeding, inquiry or investigation in respect of which indemnification is or might reasonably be considered to be provided for herein, unless the Indemnifying Party has consented in writing thereto, and the Indemnifying Party shall not be liable for any settlement of any such claim, action, suit, proceeding, inquiry or investigation unless it has consented in writing thereto.

RE:     ATS Automation Tooling Systems Inc.
Re:      Rights Offering          

Dear Sirs/Mesdames:

     We have acted as counsel to ATS Automation Tooling Systems Inc. (the “Company”) in connection with the distribution of • rights (“Rights”) of the Company (the “Rights Offering”) pursuant to a short form prospectus dated • , 2007 (the “Prospectus”). Each • Rights entitle the holder to acquire one common share of the Company (the “Offered Shares”) on payment of a subscription price equal to $ • .

     This opinion is provided to you pursuant to Section 7.2(f) of the standby purchase agreement (the “Standby Purchase Agreement”) dated • , 2007 among the Company and Goldman Sachs Canada Inc., Goodwood Inc. and Mason Capital • (the “Standby Purchasers”) as a condition to completing the closing of the purchase by the Standby Purchasers of certain common shares of the Company (the “Standby Shares” and, together with the Rights Offering Shares, the “Offered Shares”) from the Company. All capitalized terms used in this opinion shall, unless otherwise defined herein, have the meanings ascribed to them in the Standby Purchase Agreement. “Applicable Securities Laws” means the applicable securities legislation, rules and regulations of each of the provinces of Canada.

     As counsel to the Company we have participated in the preparation of, among other things:

(a) the Prospectus; and

-37-

(b) the Standby Purchase Agreement.

     We have considered such questions of law, examined such statutes and regulations and made such investigations and examined originals or copies certified, authenticated or otherwise identified to our satisfaction, of records and corporate proceedings, certificates and other documents as we have considered to be necessary or relevant for the purposes of the opinions hereinafter expressed, including the following:

(a)	the currently effective articles and by-laws of the Company;
(b)	a certified copy of the resolutions of the Board of Directors of the Company, authorizing, inter alia, the Prospectus, the Standby Purchase Agreement, the creation and issuance of the Rights and the issuance of the Offered Shares;
(c)	a certificate of even date herewith of the [Secretary] of the Company as to certain factual matters (the “General Certificate”);
(d)	a certificate of status in respect of the Company issued by Ontario Ministry of Government Services and dated • , 2007 (the “Certificate of Status”);
(e)	a letter from the Toronto Stock Exchange (the “TSX”) dated • , 2007 relating to the approval for listing of the Rights and the Offered Shares on the TSX (the “Listing Letter”); and
(f)	a copy of the decision document for the Prospectus dated • , 2007 issued by the Ontario Securities Commission under the mutual reliance review system, evidencing that receipts of the regulators in each Canadian province have been issued for the Prospectus (the “MRRS Decision Document”), and copies of local receipts for the Prospectus where issued.

     In our examinations, we have assumed: (i) the genuineness of all signatures; (ii) the authenticity of all documents submitted to us as originals; (iii) the conformity to authentic original documents of all documents submitted to us as certified, conformed or photostatic copies or facsimiles thereof; (iv) the legal capacity of all individuals; and (v) that the statements made by governmental officials in certificates provided by them are true and correct as at the time they were made and continue to be true and correct from such time to the time of delivery of this opinion.

     With respect to the opinion in paragraph 1, we have relied exclusively on the Certificate of Status.

     With respect to the opinions in paragraphs 2, 3, 4, 6 and 7, we have relied as to certain matters of fact on the General Certificate.

     In expressing the opinion in paragraph 7, we have assumed that the Standby Purchase Agreement has been duly authorized, executed and delivered by all parties thereto other than the

-38-

Company and that such document constitutes a legal, valid and binding obligation of each of the parties thereto other than the Company and is enforceable in accordance with its terms against all parties thereto other than the Company, subject to the qualifications on enforceability referred to below.

     With respect to the opinion in paragraph 9, we have relied on the MRRS Decision Document.

     In expressing the opinion set forth in paragraph 9, we have assumed that the Prospectus (including the documents incorporated by reference therein) (i) constitutes full, true and plain disclosure of all material facts relating to the Company, the Rights and the Offered Shares as required by Applicable Securities Laws; (ii) does not contain any misrepresentation likely to affect the value or market price of the Rights or the Offered Shares; (iii) does not contain any untrue statement of a material fact, (iv) does not omit to state a material fact that is required to be stated or that is necessary to make a statement not misleading in light of the circumstances in which it was made, and (v) ATS is not a “connected issuer” or “related issuer” of any of the Standby Purchasers or dealer managers for the Rights Offering.

     In expressing the opinion in paragraph 9, we have assumed that no material change (as defined in the Securities Act (Ontario) (the “Securities Act”) or other Applicable Securities Laws has occurred since the date of the Prospectus, which would require the Company to file an amendment to the Prospectus (including by way of filing a document which would be incorporated by reference therein) pursuant to the Securities Act or other Applicable Securities Laws. We have also assumed that the dealer managers for the Rights Offering are duly registered under Applicable Securities Laws to trade the Rights and Offered Shares in such jurisdictions where such Rights and Offered Shares have been or will be distributed and have complied with all Applicable Securities Laws in the course of the Rights Offering. We have also assumed that at all material times, no order of any court or competent regulatory authority has been or will have been issued to cease, restrict or suspend the trade or distribution of any securities of the Company, or that affects any person who engages in such a trade, and no court judgment, order, decree, injunction, decision or ruling will be in effect which prevents the trade or distribution of securities of the Company, or that affects any person who engages in such trade.

     We are members of the Bar in the provinces of British Columbia, Alberta, Ontario and Québec, and are qualified to express opinions only in respect of the laws of those provinces and the federal laws of Canada applicable therein. We do not express or imply any opinion in respect of the laws of any jurisdiction other than the Province of Ontario and the laws of Canada applicable therein, except with respect to the opinion in paragraph 9, in which we also express an opinion in respect of the laws of the provinces of British Columbia, Alberta and Québec. Insofar as our opinion pertains to matters governed by or related to the laws of any jurisdiction other than the Province of Ontario and the laws of Canada applicable therein and, as stated previously, the laws of the provinces of British Columbia, Alberta and Québec, we have relied on the opinions described below.

     We have relied exclusively upon the following opinions of local counsel (collectively, the “Local Counsel Opinions”) dated the date hereof in giving the opinion in paragraph 9 relating to

-39-

the application of the laws in the jurisdiction of each of the counsel listed below, copies of which opinions are being delivered to you with this opinion, all of which are in form and scope satisfactory to us:

(a)	[MacPherson Leslie & Tyerman LLP] (with respect to the laws of the Province of Saskatchewan);
(b)	[Taylor McCaffrey LLP] (with respect to the laws of the Province of Manitoba); and
(c)	[Stewart McKelvey Stirling Scales] (with respect to the laws of the provinces of New Brunswick, Prince Edward Island, Nova Scotia and Newfoundland and Labrador).

     To the extent that any Local Counsel Opinion is stated to be based on any assumption, to be given in reliance on any certificate or other document or to be subject to any limitation, qualification or exception, the opinion expressed herein in reliance on such Local Counsel Opinion is based upon the same assumption, is given in reliance on the same certificate or documents, and is subject to the same limitation, qualification or exception.

     Nothing has come to the attention of the members of this firm who have been actively involved in advising the Company in connection with the transaction described herein to suggest that you and we are not justified in relying on the Local Counsel Opinions; however, we have not independently considered the matters covered by such opinions.

     In expressing the opinion in paragraph 10, we have relied exclusively on the Listing Letter.

     The opinions herein with respect to enforceability are subject to all applicable bankruptcy, insolvency, reorganization, moratorium and other laws affecting the enforcement of the rights of creditors generally and to the discretion of the courts in granting equitable remedies, including the remedies of specific performance and injunction. The opinions herein with respect to the enforceability of the Standby Purchase Agreement are further subject to the qualifications that: (a) the validity and enforceability of the provisions in any documentation which purports to sever from such document any provision which is prohibited or unenforceable under applicable law without affecting the enforceability or validity of the remainder of the said document would be determined in the discretion of the court; (b) the enforceability of any provision of any documentation exempting a person from a liability or duty otherwise owed by it, waiving legal and equitable defences, agreeing not to challenge the validity or enforceability of remedies or that provides that a determination or calculation made by a person is conclusive and binding on any other person may be limited under applicable law; (c) the costs of and incidental to proceedings taken in court are in the discretion of the court and the court has full power to determine by whom and to what extent such costs shall be paid; (d) we express no opinion with respect to the validity and enforceability of any provision in the Standby Purchase Agreement that suggests that modifications, amendments or waivers of or with respect to such Transaction Document that are not in writing will be ineffective; (e) pursuant to the Currency Act (Canada), a

-40-

judgment by a court in any province in Canada may be awarded in Canadian currency only and such judgment may be based on a rate of exchange in existence on a day other than the day of payment of such judgment; and (f) the enforceability of such document will be subject to the limitations contained in the Limitations Act, 2002 (Ontario) and we express no opinion as to whether a court may find any provision in such document to be unenforceable on the basis that such provision is an attempt to vary or exclude a limitation period under such Act. In addition, we express no opinion as to the enforceability of the indemnity and contribution provisions of the Standby Purchase Agreement or any other agreement relating to the Rights Offering nor do we express any opinion as to whether such provisions do not contravene any laws of the provinces of British Columbia, Alberta, Ontario or Québec or the federal laws of Canada applicable therein.

     The opinions hereinafter expressed are based on legislation and regulations in effect on the date hereof.

     Based upon and subject to the foregoing, we are of the opinion that on the date hereof:

1.	The Company is a corporation existing under the laws of the Province of Ontario and has not been dissolved.
2.	The Company has the requisite power and capacity to carry on its business as described in the Prospectus, to enter into and carry out its obligations under the Standby Purchase Agreement and to issue the Rights and Offered Shares as contemplated by the Prospectus and the Standby Purchase Agreement.
3.	The execution and delivery of the Prospectus and the filing of the Prospectus pursuant to Applicable Securities Laws have been duly approved and authorized by all necessary action on the part of the Company.
4.	All necessary action has been taken by and on behalf of the Company to authorize the creation, issuance and distribution of the Rights and the Offered Shares.
5.	The Rights have been duly authorized and validly issued, and upon payment of the subscription price and the valid exercise of the Rights as contemplated in the Prospectus, the Offered Shares will be duly authorized and validly issued as fully-paid and non-assessable common shares in the capital of the Company.
6.	Neither the execution and delivery by the Company of the Standby Purchase Agreement nor the consummation of the transactions contemplated by the Standby Purchase Agreement resulted, or will result, in a breach (whether after notice or lapse of time or both) of: (a) any of the terms, conditions or provisions of the articles or by-laws of the Company; or (b) any applicable laws of the Province of Ontario or the federal laws of Canada applicable therein.
7.	The Standby Purchase Agreement and the performance by the Company of its obligations thereunder have been duly authorized and the Standby Purchase

-41-

Agreement has been duly executed and delivered by the Company and constitutes a legal, valid and binding obligation of the Company enforceable against it in accordance with its terms.

8.	Based on the provisions of the Income Tax Act (Canada) (the “Tax Act”), the Regulations thereunder, and the proposals to amend the Tax Act and the Regulations publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof, the Offered Shares, when issued will be qualified investments under the Tax Act and the regulations thereunder for trusts governed by registered retirement savings plans, registered retirement income funds, deferred profit sharing plans and registered education savings plans, provided that the common shares of the Company are listed at that time on a prescribed stock exchange in Canada (which currently includes the TSX) or, if the amendments to the Tax Act proposed in the federal budget released on March 19, 2007 are enacted, a “designated” stock exchange in Canada (which it is expected would also include the TSX).
9.	All necessary documents have been filed, all requisite proceedings have been taken and all legal requirements have been fulfilled by the Company under Applicable Securities Laws to qualify the Offered Shares for distribution in each Canadian province through registrants registered under the applicable legislation in the respective province who comply with the relevant provisions of such applicable legislation.
10.	The Offered Shares have been approved for listing on the TSX, subject only to such usual conditions and to the filing of usual documents in accordance with the requirements of the TSX.

* * * * * *

     This opinion is rendered solely to the addressees in connection with the Rights Offering and the Standby Purchase Agreement and may not be used or relied upon by you for any other purpose or used or relied upon by any other person, nor quoted from or referred to in any documents without our prior written consent. This opinion is given as of the date hereof and we disclaim any obligation or undertaking to advise you of any change in law or fact affecting or bearing upon this opinion occurring after the date hereof which come, or are brought, to our attention.

Yours very truly,
