Here;s what the Tariff tells us about alcohol:
49. Alcohol may qualify under tariff item No. 9807.00.00 as settler’s effects only if, the settler meets the minimum age requirements, these goods accompany the settler on arrival in Canada, and the quantity limits are not exceeded.
50. Settlers can include in their personal exemption, up to either 1.14 litres of alcohol or, 1.5 litres of wine or, a total of 1.14 litres of alcohol and wine.
51. The minimum legal ages for the importation of alcoholic beverages under the laws of the province or territory are:
(a) 18 years for Alberta, Manitoba and Quebec; and
(b) 19 years for Yukon, the Northwest Territories, Nunavut, British Columbia, Saskatchewan, Ontario, Nova Scotia, New Brunswick, Prince Edward Island and Newfoundland and Labrador.
52. Settlers intending to ship alcoholic beverages to Canada (e.g., the contents of a bar or wine cellar) are advised to contact the appropriate liquor control board, prior to shipment, so that provincial fees and assessments can be paid in advance. In order to obtain release of the shipment in Canada, the settler must produce a copy of the provincial permit and pay all of the applicable CBSA assessments.
So yes, you will have to pay duties on your collection, and at least a part of it in advance so you could cross with the bottles.
