According to forum posts, one recommended itinerary for traveling across Canada includes starting in Toronto, then moving to Ottawa, Montreal, and Quebec City. Travelers have suggested spending about 2-3 days in each city to explore the main attractions. From Quebec, you can travel westward, stopping at major cities and attractions along the way, like the Canadian Rockies, Vancouver, and possibly Calgary.

Some travelers said that focusing on specific regions can enhance the travel experience due to Canada's vast size. For example, you could explore Eastern Canada, covering Montreal, Quebec City, and Ottawa, or opt for Western Canada, which includes destinations like Vancouver, the Canadian Rockies, and Calgary. Each region offers unique landscapes and cultural experiences.

For those interested in wildlife and history, forum users recommend including destinations like the Canadian Rockies for nature and wildlife, and cities like Ottawa and Quebec City for historical sites. Churchill, Manitoba, is also a notable mention for its unique polar bear and beluga whale sightings.

Travelers have called out the importance of scenic routes such as the Icefields Parkway, which is highly recommended for its breathtaking views. Planning a drive across provinces like Alberta and British Columbia can provide opportunities to visit national parks and engage in outdoor activities.

According to forum posts, Toronto, Montreal, and Vancouver are must-visit cities in Canada. Toronto is known for its vibrant multicultural environment and extensive urban activities. Montreal offers a blend of North American and European cultures with a predominant French influence, making it unique in terms of language and cultural offerings.

Travelers have called out Quebec City for its European charm and historical significance, making it a favorite for those interested in history and architecture. Ottawa, as the capital, is also highlighted for its national museums and cultural institutions.

For nature lovers, posts suggest cities like Calgary as gateways to natural wonders like the Canadian Rockies and Banff National Park. Vancouver is praised for its proximity to both mountains and the ocean, offering diverse outdoor activities year-round.

According to forum posts, the Canadian eTA (Electronic Travel Authorization) is required for visa-exempt foreign nationals flying to Canada. It's essential to apply through the official Government of Canada website (Canada.ca/eTA), and the cost is $7 Canadian. Applications should be made as early as possible since approval times can vary.

Some travelers mentioned that an eTA is valid for five years or until the passport expires, whichever comes first. It's important to note that while an eTA allows you to board a flight to Canada, it does not guarantee entry into the country, which is determined by Canadian Customs and Immigration at the point of entry.

Travelers have called out that those who have ever held Canadian citizenship should not apply for an eTA but must use a Canadian passport. Additionally, an eTA is not required for entry into Canada by land or sea, only by air.

According to forum posts, travelers entering Canada must be fully vaccinated and have completed the ArriveCAN app submission within 72 hours before arrival. Additionally, a valid passport is required for entry.

Some travelers noted that there are no pre-entry testing requirements for fully vaccinated individuals, but a random selection for a PCR test upon arrival is possible. Travelers should also have a quarantine plan ready, even if not required to use it, in case they are symptomatic or do not meet the fully vaccinated criteria upon arrival.

For minors, especially when traveling by land, it has been mentioned that American children can enter Canada with just a birth certificate, without a passport. This information is confirmed on the U.S. State Department's website, but travelers are advised to verify on Canadian sites or directly with Canadian authorities.

According to forum posts, VIA Rail is the primary provider for cross-country train travel in Canada, offering routes such as The Canadian, which travels from Toronto to Vancouver. This service allows travelers to experience multiple time zones and diverse landscapes.

Some travelers have highlighted the Rocky Mountaineer as a luxury option, offering routes like First Passage to the West and Journey Through the Clouds between Vancouver and the Canadian Rockies. This service is known for its scenic views and high-end amenities but comes at a higher cost compared to VIA Rail.

Travelers have called out that while VIA Rail offers a more budget-friendly option with sleeper and seating accommodations, it does not prioritize its trains on tracks, leading to potential delays. The Rocky Mountaineer is praised for its exclusive focus on daylight travel, ensuring passengers do not miss the scenic views.

For planning and booking, users have recommended resources like the VIA Rail website and the Man in Seat 61 website for detailed information on routes and accommodations. These resources can assist travelers in making informed decisions based on their budget and travel preferences.

According to forum posts, the Canadian Rockies are renowned for their stunning national parks such as Banff, Jasper, and Yoho. These areas are highlighted for their accessibility and the breathtaking wilderness they offer. Lake Louise is particularly famous for its iconic views and is a must-visit for travelers.

For travelers seeking less crowded spots, forum users suggest exploring places like Monkman Provincial Park, the Chilcotins, and the Yukon for a more secluded experience. These areas are noted for their remote beauty and fewer tourist footprints.

Travelers have called out the importance of timing your visit for optimal experiences. Mid to late June is recommended for thawing of the iconic glacial lakes and better hiking conditions on higher elevation trails. Early June might still see some trails snowbound.

According to forum posts, travelers looking to explore between Vancouver and Calgary have a few scenic options. One common recommendation is the Sea to Sky Highway, which provides stunning views along Howe Sound and through the Coast Mountains. This route is distinct from the Rockies and offers a combination of ocean and rainforest landscapes that are unique to the area.

For those preferring a more traditional mountain experience, routes such as the Trans-Canada Hwy BC-1 and the Crowsnest Hwy BC-3 are popular. These highways offer opportunities to explore various mountain ranges and parks, including stops in towns like Revelstoke, known for its access to Glacier National Park. These routes provide a mix of wilderness and urban areas, catering to different preferences for scenery and activities.

Some travelers have suggested using Hwy 3, the Crowsnest Highway, for those who prefer a quieter journey with less traffic and rich scenic views. Each route offers unique landscapes and attractions, making them suitable for diverse travel interests and allowing for customizable road trip experiences.

According to forum posts, a criminal record can significantly impact eTA eligibility for Canada. Several travelers have shared their experiences of delays and additional documentation requests after disclosing past convictions. For example, one user noted a lengthy eTA processing time after declaring a DUI conviction from over 10 years ago, indicating that even older offenses could trigger a review process.

Travelers have called out that when applying for an eTA with a criminal record, Immigration, Refugees and Citizenship Canada (IRCC) often requires supplementary documentation, such as police certificates. Some users reported that after submitting the required documents, it took weeks or even months to receive eTA approval, suggesting a thorough review by Canadian immigration authorities.

For many users, the general advice is to apply for an eTA well in advance if they have a criminal record. This allows ample time for potential additional reviews or document requests. Additionally, being truthful and providing all requested documentation upfront can facilitate the process, as seen in cases where users eventually received their eTA after complying with all IRCC requirements.
