Sec. 1.955  Frequency coordination, Canada.

    (a) As a result of mutual agreements, the Commission has, since May 
1950 had an arrangement with the Canadian Department of Communications 
for the exchange of frequency assignment information and engineering 
comments on proposed assignments along the Canada-United States borders 
in certain bands above 30 MHz. Except as provided in paragraph (b) of 
this section, this arrangement involves assignments in the following 
frequency bands.

                                   MHz

30.56-32.00
33.00-34.00
35.00-36.00
37.00-38.00
39.00-40.00
42.00-46.00
47.00-49.60
72.00-73.00
75.40-76.00
150.80-174.00
450-470
806.00-960.00
1850.0-2200.0
2450.0-2690.0
3700.0-4200.0
5925.0-7125.0

                                   GHz

10.55-10.68
10.70-13.25

    (b) The following frequencies are not involved in this arrangement 
because of the nature of the services:

                                   MHz

156.3
156.35
156.4
156.45
156.5
156.55
156.6
156.65
156.7
156.8
156.9
156.95
157.0 and 161.6
157.05
157.1
157.15
157.20
157.25
157.30
157.35
157.40.

    (c) Assignments proposed in accordance with the railroad industry 
radio frequency allotment plan along the United States-Canada borders 
utilized by the Federal Communications Commission and the Department of 
Transport, respectively, may be excepted from this arrangement at the 
discretion of the referring agency.
    (d) Assignments proposed in any radio service in frequency bands 
below 470 MHz appropriate to this arrangement, other than those for 
stations in the Domestic Public (land mobile or fixed) category, may be 
excepted from this arrangement at the discretion of the referring agency 
if a base station assignment has been made previously under the terms of 
this arrangement or prior to its adoption in the same radio service and 
on the same frequency and in the local area, and provided the basic 
characteristics of the additional station are sufficiently similar 
technically to the original assignment to preclude harmful interference 
to existing stations across the border.
    (e) For bands below 470 MHz, the areas which are involved lie 
between Lines A and B and between Lines C and D, which are described as 
follows:


[[Page 200]]


    Line A-- Begins at Aberdeen, Wash., running by great circle arc to 
the intersection of 48 deg. N., 120 deg. W., thence along parallel 
48 deg. N., to the intersection of 95 deg. W., thence by great circle 
arc through the southernmost point of Duluth, Minn., thence by great 
circle arc to 45 deg. N., 85 deg. W., thence southward along meridian 
85 deg. W., to its intersection with parallel 41 deg. N., thence along 
parallel 41 deg. N., to its intersection with meridian 82 deg. W., 
thence by great circle arc through the southernmost point of Bangor, 
Maine, thence by great circle arc through the southern-most point of 
Searsport, Maine, at which point it terminates; and
    Line B-- Begins at Tofino, B.C., running by great circle arc to the 
intersection of 50 deg. N., 125 deg. W., thence along parallel 50 deg. 
N., to the intersection of 90 deg. W., thence by great circle arc to the 
intersection of 45 deg. N., 79 deg.30' W., thence by great circle arc 
through the northernmost point of Drummondville, Quebec (lat: 45 deg.52' 
N., long: 72 deg.30' W.), thence by great circle arc to 48 deg.30' N., 
70 deg. W., thence by great circle arc through the northernmost point of 
Campbellton, N.B., thence by great circle arc through the northernmost 
point of Liverpool, N.S., at which point it terminates.
    Line C-- Begins at the intersection of 70 deg. N., 144 deg. W., 
thence by great circle arc to the intersection of 60 deg. N., 143 deg. 
W., thence by great circle arc so as to include all of the Alaskan 
Panhandle; and
    Line D-- Begins at the intersection of 70 deg. N., 138 deg. W., 
thence by great circle arc to the intersection of 61 deg.20' N., 
139 deg. W., (Burwash Landing), thence by great circle arc to the 
intersection of 60 deg.45' N., 135 deg. W., thence by great circle arc 
to the intersection of 56 deg. N., 128 deg. W., thence south along 
128 deg. meridian to Lat. 55 deg. N., thence by great circle arc to the 
intersection of 54 deg. N., 130 deg. W., thence by great circle arc to 
Port Clements, thence to the Pacific Ocean where it ends.

    (f) For all stations using bands between 470 MHz and 1000 MHz; and 
for any station of a terrestrial service using a band above 1000 MHz, 
the areas which are involved are as follows:
    (1) For a station the antenna of which looks within the 200 deg. 
sector toward the Canada-United States borders, that area in each 
country within 35 miles of the borders;
    (2) For a station the antenna of which looks within the 160 deg. 
sector away from the Canada-United States borders, that area in each 
country within 5 miles of the borders; and
    (3) The area in either country within coordination distance as 
described in Recommendation 1A of the Final Acts of the EARC, Geneva, 
1963 of a receiving earth station in the other country which uses the 
same band.
    (g) Proposed assignments in the space radiocommunication services 
and proposed assignments to stations in frequency bands allocated 
coequally to space and terrestrial services above 1 GHz are not treated 
by these arrangements. Such proposed assignments are subject to the 
regulatory provisions of the International Radio Regulations.
    (h) Assignments proposed in the frequency band 806-890 MHz shall be 
in accordance with the Canada-United States agreement, dated April 7, 
.
