Written by Acorn Sales Company, manufacturing stamps and seals since 1964 · Reviewed by Holly R, VP of Sales and Marketing at Acorn Sales, against not a single body: land surveying in Canada is regulated provincially by each province’s association of land surveyors, and separately on Canada Lands by the Association of Canada Lands Surveyors and Ontario: Surveyors Act, R.S.O. 1990, c. S.29 on 21 September 2026 · Updated 21 September 2026
There is no Canadian land surveyor seal, because there is no Canadian land surveying regulator. Jurisdiction is split twice over: each province regulates surveying within its own boundaries through its own association of land surveyors, and the Association of Canada Lands Surveyors separately governs its members’ cadastral surveying on Canada Lands, licensing practitioners and issuing permits to companies to work there. A Canadian surveyor may need two credentials for two bodies of land, and neither is national in the sense of covering the other. The regulator verified in full for this page is Ontario, and nothing here should be applied outside it.
In Ontario the seal comes from the Association rather than from a supplier. R.R.O. 1990, Reg. 1026 under the Surveyors Act, s. 29(1): “Every member shall obtain from the Association the appropriate seal for his or her class of membership.” Section 29(2) takes it back: “A member of the Association shall return his or her seal upon the suspension or cancellation of his or her licence, limited licence, temporary licence or certificate of registration.” Suspension counts, not only cancellation.
The sharpest device rule sits in s. 29(3), and it is narrow. A print of a plan of survey other than one deposited or registered in the Ontario land registration system is not a valid copy unless it bears an embossed seal. That is a validity condition on a class of prints, not a general statement that every Ontario surveying device must be an embosser.

Is a seal required in Canada?
Do not read this as a national answer. Surveying jurisdiction in Canada is split twice over: each province regulates surveying within its own boundaries, and the Association of Canada Lands Surveyors governs the activities of its members in cadastral surveying on Canada Lands, licensing practitioners and issuing permits to companies to work on those lands. The regulator we verified in full is Ontario. There, R.R.O. 1990, Reg. 1026 under the Surveyors Act, s. 29(1), provides that “Every member shall obtain from the Association the appropriate seal for his or her class of membership,” and s. 29(3) makes the seal the thing that validates a copy of a plan of survey.
What must appear on the seal
- Ontario: whatever appears on the seal the Association supplies for your class of membership, since the member obtains the seal from the Association rather than specifying one
Ontario publishes no element list because the Association supplies the device, and it supplies a different one per class of membership. The titles those classes carry are set out at s. 28: a license or certificate of registration holder may use “Ontario Land Surveyor” or the initials O.L.S., and “Ontario Land Information Professional” or O.L.I.P.; a limited license holder uses “Ontario Land Surveyor (Limited Licence)” or O.L.S. (LL); a temporary license holder uses “Ontario Land Surveyor (Temporary)” or O.L.S. (T). A partnership or corporation holding a valid certificate of authorization may use the same titles as an occupational designation.
Size and shape
Not applicable in the usual sense for Ontario, because the Association supplies the seal. Regulation 1026 prescribes no diameter and no layout. Not verified for any other Canadian regulator. The provincial associations and the Association of Canada Lands Surveyors each set their own requirements and were not read at the time of writing.
Embosser, rubber stamp or digital
Ontario requires an embossed seal for a print of a plan of survey, and the point is narrow. Section 29(3): “A print of a plan of survey other than a plan deposited or registered in the Ontario land registration system is not a valid copy unless it bears the embossed seal of the licensed member who signed the plan or the embossed seal of a licensed member employed by the corporation or public agency responsible for the plan’s preparation or the corporate seal of the corporation holding a certificate of authorization that was responsible for the plan’s preparation.” Read the subject: this is a validity rule for prints of plans outside the land registration system, not a general statement that every Ontario surveying device must be an embosser.
Signing and dating
Ontario ties the embossed seal on a print to the member who signed the plan, so a signature is presupposed by s. 29(3). Not addressed in the provisions we read: the placement of the signature relative to the impression, and any date requirement. Note the separate device at s. 30: “Every licensed member shall obtain approval from the Registrar of the survey monument identification stamp to be used by that member,” and s. 30(2) requires the member to identify every survey monument planted with the approved identification stamp. That is a field marking tool, not a paper seal, and it needs its own Registrar approval.
Two layers of jurisdiction, and in Ontario an embossed seal decides whether a print is a valid copy
Canada splits surveying twice. Each province regulates surveying within its boundaries through its own association of land surveyors, and the Association of Canada Lands Surveyors separately governs its members’ cadastral surveying on Canada Lands, licensing practitioners and issuing permits to companies authorized to work there. A Canadian surveyor may therefore need two credentials for two bodies of land, and neither is national in the sense of covering the other.
Which documents must be sealed
Ontario: prints of plans of survey other than plans deposited or registered in the Ontario land registration system are not valid copies without the embossed seal. Survey monuments planted by a licensed member must be identified with the monument identification stamp approved for that member by the Registrar. Not verified for the other provincial associations or for the Association of Canada Lands Surveyors, whose cadastral work on Canada Lands is governed by its own instruments.
Electronic and digital seals
Not verified. The seal provisions of R.R.O. 1990, Reg. 1026 that we read set no electronic or digital sealing standard. Given that s. 29(3) conditions the validity of a print on an embossed seal, the electronic question in Ontario is one to put to the Association of Ontario Land Surveyors directly rather than to assume. Nothing here is verified for any other Canadian regulator.
Renewal, lapse and retirement
Ontario requires the seal back. Section 29(2): “A member of the Association shall return his or her seal upon the suspension or cancellation of his or her licence, limited licence, temporary licence or certificate of registration.” Suspension counts, not only cancellation. That matches the Ontario architectural pattern and is the opposite of the US norm, where a lapsed licensee simply stops using a device that remains in their possession.
Firm requirements
Ontario recognizes a corporate seal. Section 29(3) accepts, as an alternative to the embossed seal of the licensed member who signed the plan, “the corporate seal of the corporation holding a certificate of authorization that was responsible for the plan’s preparation,” and s. 22 of the Regulation governs certificates of authorization. Section 28(2) allows a partnership or corporation holding a valid certificate of authorization to use Ontario Land Surveyor or Ontario Land Information Professional as an occupational designation. So in Ontario a firm device is a real thing on a print of a plan.
What to check before you order
There is no Canadian land surveyor seal to order, because surveying is regulated province by province and separately on Canada Lands by the Association of Canada Lands Surveyors. In Ontario the member obtains the seal from the Association of Ontario Land Surveyors for the member’s class of membership and returns it on suspension or cancellation, so there is nothing for a supplier to make. Note the one device rule worth knowing there: a print of a plan of survey outside the land registration system is not a valid copy unless it bears an embossed seal, either the signing member’s or the corporate seal of the certificate of authorization holder responsible for the plan. Ontario members also need a survey monument identification stamp approved by the Registrar. For any other province, or for Canada Lands, ask that regulator first.
The regulator supplies the official device itself, so that part does not come from a stamp supplier. Go to the regulator named above for it.
What we can still make for you. The rule governs the official seal, not everything else that goes on a drawing or across a desk. Licensees on regulator-issued credentials regularly order supplemental devices from us: a raised embosser for the client copy or title sheet, a name and license block stamp, a "reviewed" or "as built" marker, a firm address stamp, or a duplicate of the official artwork for internal drafts where the official device would be inappropriate. None of those stands in for the seal, and none is what the rule restricts. Tell us what the regulator issued you and we will make the rest around it. Browse land surveyor stamps and seals.
Frequently asked questions
Is there a single Canadian land surveyor seal standard?
No. Each province regulates surveying within its boundaries through its own association of land surveyors, and the Association of Canada Lands Surveyors governs the activities of its members in cadastral surveying on Canada Lands, licensing practitioners and issuing permits to companies authorized to work on those lands. The two layers do not substitute for one another.
Who supplies the seal in Ontario?
The Association. R.R.O. 1990, Reg. 1026, s. 29(1) provides that “Every member shall obtain from the Association the appropriate seal for his or her class of membership,” and a different device goes with each class. There is nothing for a stamp supplier to make, so the request goes to the Association of Ontario Land Surveyors.
What appears on an Ontario land surveyor seal?
Whatever the Association puts on the seal it supplies for your class of membership. Ontario publishes no element list, because the member obtains the device rather than specifying one, and Regulation 1026 prescribes no diameter and no layout.
What titles go with the Ontario classes of membership?
Section 28 sets them out. A license or certificate of registration holder may use “Ontario Land Surveyor” or the initials O.L.S., and “Ontario Land Information Professional” or O.L.I.P. A limited license holder uses “Ontario Land Surveyor (Limited Licence)” or O.L.S. (LL). A temporary license holder uses “Ontario Land Surveyor (Temporary)” or O.L.S. (T). A partnership or corporation holding a valid certificate of authorization may use the same titles as an occupational designation.
When does an Ontario print of a plan need an embossed seal?
When it is not in the land registration system. Section 29(3): “A print of a plan of survey other than a plan deposited or registered in the Ontario land registration system is not a valid copy unless it bears the embossed seal of the licensed member who signed the plan or the embossed seal of a licensed member employed by the corporation or public agency responsible for the plan’s preparation or the corporate seal of the corporation holding a certificate of authorization that was responsible for the plan’s preparation.” Read the subject: it is a validity rule for a class of prints, not a ban on inked devices generally.
What is the Ontario survey monument identification stamp?
A second, separate device with its own approval. Section 30: “Every licensed member shall obtain approval from the Registrar of the survey monument identification stamp to be used by that member,” and s. 30(2) requires the member to identify every survey monument planted with the approved identification stamp. It is a field marking tool rather than a paper seal.
Can an Ontario corporation seal a plan?
Yes, in the s. 29(3) list. The corporate seal of the corporation holding a certificate of authorization that was responsible for the plan’s preparation is accepted as an alternative to the embossed seal of the licensed member who signed the plan. Section 22 of the Regulation governs certificates of authorization, and s. 28(2) allows a partnership or corporation holding a valid certificate to use Ontario Land Surveyor or Ontario Land Information Professional as an occupational designation. So in Ontario a firm device is a real thing on a print of a plan.
Does Ontario allow electronic sealing?
Not verified. The seal provisions of Reg. 1026 that were read, ss. 28 to 30, set no electronic or digital sealing standard. Given that s. 29(3) conditions the validity of a print on an embossed seal, the electronic question in Ontario is one to put to the Association of Ontario Land Surveyors directly rather than to assume, and nothing here is verified for any other Canadian regulator.
What happens to my Ontario seal if my license is suspended?
It goes back. Section 29(2) requires a member to return the seal on the suspension or cancellation of a license, limited license, temporary license or certificate of registration. Suspension is enough, which is the opposite of the US norm where a lapsed licensee simply stops using a device that stays in their possession.
Does Ontario say where the signature goes?
Not in the provisions read here. Section 29(3) ties the embossed seal on a print to the member who signed the plan, so a signature is presupposed, but the placement of the signature relative to the impression and any date requirement are not addressed in ss. 28 to 30.
What about the other provinces and Canada Lands?
Ask that regulator. The provincial associations other than Ontario and the Association of Canada Lands Surveyors each set their own requirements, and none of them was read for this page, so no dimension, device type, signature rule or date rule is reported for them. The Canada Lands Surveyors Act text was likewise not reached.
