This document has official status.
chapter A-25, r. 2
Regulation respecting permanent impairments
Automobile Insurance Act
(chapter A-25, s. 195, par. 12).
This Regulation remains in force and continues to apply to accidents and deaths having occured between 1 January 1990 and 31 December 1999. (1999, chapter 22, s. 44)
DIVISION I
SCHEDULE OF PERMANENT IMPAIRMENTS
1. The schedule of permanent impairments and the percentages assigned for each impairment appear in Schedule I.
O.C. 1921-89, s. 1.
DIVISION II
ENHANCEMENT FOR SYMMETRICAL ORGANS
1.1. Where permanent anatomicophysiological deficits affect internal organs or organs controlling vision, balance and hearing, an enhancement factor taking bilaterality into account is already included in the percentages set forth in Schedule I.
O.C. 766-96, s. 1.
1.2. Where permanent impairment of organs or symmetrical limbs is the result of damage to the central nervous system, an enhancement factor taking inherent bilaterality into account is already included in the percentages set forth in Schedule I.
O.C. 766-96, s. 1.
2. Where permanent anatomicophysiological deficits affect symmetrical limbs or a limb symmetrical to one that is already impaired, the average of the percentages of the anatomicophysiological deficits for both limbs is multiplied by an enhancement factor of one-quarter, up to the sum of percentages of the lesser damaged limb.
The average is obtained by adding together the percentage of anatomicophysiological deficit of each of the two symmetrical limbs and dividing the sum by 2.
The percentage so obtained is added to the percentages of anatomicophysiological deficits resulting from the accident.
Symmetrical deficits are established on a limb-to-limb basis: the upper right limb with the upper left limb and the lower right limb with the lower left limb. The upper limb includes the scapula and clavicle. The lower limb includes the pelvis.
O.C. 1921-89, s. 2; O.C. 766-96, s. 2.
3. (Revoked).
O.C. 1921-89, s. 3; O.C. 766-96, s. 3.
4. The percentage of a deficit prior to the accident is fixed, for purposes of applying section 2, according to the schedule appearing in Schedule I, or, if this deficit is not mentioned in the schedule, according to deficits of the same type mentioned therein.
O.C. 1921-89, s. 4.
DIVISION III
COMPUTATION ON SUCCESSIVE REMAINDERS
5. Where a victim has several permanent impairments, the percentage of the most important impairment is computed on the basis of 100% and the percentages of the other impairments, starting with the highest, are computed on the successive remainders, in accordance with Schedule II.
O.C. 1921-89, s. 5.
6. The method for computing provided in section 5 does not apply to a percentage of 5% or less attributed to a permanent impairment, as such percentage must be added in full to the other percentages.
It does not apply either to the percentage obtained by applying the enhancement factor referred to in section 2.
O.C. 1921-89, s. 6.
DIVISION IV
COMBINATION OF THE COMPUTATION ON SUCCESSIVE REMAINDERS AND THE ENHANCEMENT FOR SYMMETRICAL ORGANS
7. Where Divisions II and III both apply to a victim, the percentage resulting from the enhancement factor is first computed, but is only added to the other percentages of deficits once the computation on successive remainders has been made.
O.C. 1921-89, s. 7.
8. (Omitted).
O.C. 1921-89, s. 8.

PROCESS FOR EVALUATING VISION
(1) Criteria for evaluating vision
A deficit of the visual system occurs where there is a deviation from normal in one or more functions of the eye. Visual integrity requires:
(a) Integrity of corrected visual acuity for distance and close-up,
(b) integrity of the field of vision, and
(c) ocular motility without diplopia.
The evaluation of these 3 functions is necessary in determining the visual deficit. Although not of equal importance, their coordinated action is essential to optimal sight.
Other ocular functions or problems that affect the coordinated functions of the eye are awarded percentages of deficit in accordance with the scale prescribed for those functions.
(2) Methods for evaluating vision
(a) Determination of central visual acuity
Central vision is measured with the best corrected vision possible for distance and close-up, based on Tables 5 and 6.
(b) Determination of the extent of visual fields
The extent of the visual field is determined by use of the usual perimetric methods with a white target which subtends a 0.5° angle, i.e., a 3 mm white disk at a distance of 330 mm under illumination of not less than 7 f-c. A 6/330 white disk should be used for aphakia. The target is brought from the periphery to the field of vision, or from the unseen to the seen.
At least 2 peripheral fields should be obtained agreeing within 15° in each meridian.
The result is plotted on an ordinary visual field chart on each of the eight principal meridians separated from one another by 45°, as shown in Table 7.
The minimum normal extent of the visual field from the point of fixation is indicated in Table 7.
The percentage of retained visual field in one eye is obtained by adding the number of degrees of the eight principal meridians shown in Table 7 for the 3/330 isopter - which for the normal 500 degrees - and by dividing the total by 5; conversely, the percentage of deficit of visual field is obtained by adding the degrees lost, as measured according to the norms in Table 7, in each of the eight principal meridians and dividing the total by 5.
Where there is a deficit of a quadrant or a half field, the total of the deficit in each meridian must be added to half the sum of the tow adjacent meridians. The deficit of visual field can be calculated for other defects in the same way.
Table 8 shows percentages of deficit of visual field, calculated on the basis of degrees lost, expressed in increments of 5 degrees.
(c) Determination of ocular motility
Unless diplopia is present within 30 degrees of the centre of fixation, it rarely causes a visual deficit except on looking downward. The extend of the diplopia when the patient looks in various directions is determined on the perimeter at 330 mm or on any campimeter at a distance of 1 m from the patient in each of the eight principal meridians, using a small test light and without coloured lenses or correcting prisms.
The Hess Lancaster diplopia screen may also be used with the patient 1 m distance and using lenses coloured red, green, etc.
To determine loss of ocular motility:
· plot the results of the separation of 2 images on an ordinary visual field chart;
· add the corresponding percentages of loss of ocular motility caused by diplopia when the patient looks in various directions as given in Table 9.
(d) Determination of the visual efficiency of an eye
The methods described in a, b, and c above were used to evaluate:
· visual acuity,
· the field of vision, and
· ocular motility.
The percentage of visual efficiency of an eye is obtained by multiplying the percentage of visual acuity retained by the percentage of the visual field retained and by the percentage of ocular motility retained.

% of visual % of visual % of ocular % of efficiency
acuity retained field retained motility retained of eye

Right

Left
eye ________________ × _____________ × _________________ = ______________
(e) Determination of efficiency of entire visual system
Multiply the percentage of efficiency of the better eye by 3, add the percentage of efficiency of the other eye and divide the sum obtained by 4 to obtain the percentage of function of the entire visual system or efficiency of binocular vision. Subtract the percentage of efficiency of binocular vision from 100% (normal vision) to obtain the percentage of deficit for the entire visual system.

TABLE 10
ASSESSEMENT OF PLEURAL IMPAIRMENT
Pleural impairment is assessed in accordance with the 1980 ILO classification as follows:
(A) PLEURAL THICKENING:
Thickness
For pleural thickening visible along the thoracic wall, maximum thickness is measured from the osseous line of the thorax to the internal limit of the pleural opacity, as most clearly delimited:
(a) maximum thickness of under 5 mm: 1%
(b) maximum thickness of between 5 mm and 10 mm: 2%
(c) maximum thickness of over 10 mm: 3%
Front view
The presence of pleural thickening observed by a font view is notable even if it can also be seen from a side view. In the event that it is only visible by a front view, usually the thickening cannot be measured.
Extent
The extent of pleural thickening is defined in terms of maximum length of the surface observed from a front or side view:
(a) total length up to a quarter of the distance on the projection of the lateral thoracic wall: 1%
(b) total length exceeding a quarter of the distance on the projection of the lateral thoracic wall up to a half of this distance: 2%
(c) total length exceeding a half of the distance on the projection of the lateral thoracic wall: 3%
Assessment of deficit
The percentage obtained for the width is multiplied by the figure obtained for the extent, which determines the percentage of deficit assigned to the pleural thickening.
In the case of bilateral pleural thickening, the percentages are added for each side, to a total maximum allowed of 18%.
(B) FILLING OF A CAVITY
From the TT 1/1 image to the horizontal line touching the crest of the diaphram: 1 to 5%
Note: Total pleural impairment cannot exceed a maximum deficit of 20%.

DISFIGUREMENT
DIVISION I
DEFINITIONS
(1) Cicatricial impairment (scarring) means any qualitative or quantitative change in the skin; the idea includes flat and faulty scars.
(2) A flat scar is a scar that is almost linear, at the same level as the adjoining tissue and almost the same colour, causing no contraction or distortion of neighbouring structures.
(3) A faulty scar is a scar that is misaligned, irregular, depressed, deeply adhering, pigmented, scaly, retractile, keloidal or hypertrophic.
DIVISION II
DISFIGUREMENT OF THE FACE
(4) For purposes of assessing disfigurement of the face, reference is made to each of the following anatomical elements:
(1) the forehead;
(2) the orbits;
(3) the eyelids;
(4) the visible part of the ocular globes;
(5) the cheeks;
(6) the nose;
(7) the lips;
(8) the ears;
(9) the chin.
(5) The extent of disfigurement affecting the face must first be assessed overall in terms of the physiognomy, in order to determine the class of impairment.
(6) For classes 1 to 4, within the class of impairment of the physiognomy determined, the percentage of disfigurement is fixed in relation to the changes in the form and symmetry of the scarring, without exceeding the maximum percentage of disfigurement prescribed for that class, according to Table 15.
Where there are both scarring and changes in the form and symmetry, the percentages of the 2 are totalled up to the maximum percentage prescribed for the class.
(7) For classes 5 and 6, the changes in the form and symmetry and the scarring are considered as a whole and the percentage awarded is the maximum prescribed for the class, according to Table 16.
DIVISION III
DISFIGUREMENT OF OTHER PARTS OF THE BODY
(8) Where there is impairment only by changes in form and symmetry, the degree of impairment is calculated and the percentage of disfigurement prescribed for that part of the body is awarded, according to Table 17.
(9) Where there is impairment only by scarring, the surface area of the scar is measured and the percentage prescribed per cm2 is awarded, without exceeding the maximum percentage prescribed for that part of the body, according to Table 17.
(10) Where there are both changes in the form and symmetry and scarring, the higher percentage obtained under either heading is awarded, without exceeding the maximum percentage prescribed for that part of the body, according to Table 17.
