Answer 1

Added this to the result_modifier of the catalog:section component

CMain::IsHTTPS() ? $s = 's' : $s = '';
$canonical = "http$s://www.".SITE_SERVER_NAME.$APPLICATION->GetCurPage();
$APPLICATION->AddHeadString('<link href="' . $canonical . '" rel="canonical" />', true);

Where $APPLICATION is a CMain object

Any component can be customized based on what you are using. And in it already set your parameters that are necessary. https://dev.1c-bitrix.ru/learning/course/?CHAPTER_...
